Key Benefit: Lightweight

One of the standout advantages of electric pressure washers lies in their lightweight design. In comparison to their engine-driven counterparts, electric pressure washers are typically lighter, thanks to the inherent weight difference between electrical motors and traditional engines. The lighter weight of electric pressure washers not only enhances the ease of handling but also simplifies transportation and storage.

To illustrate, consider the contrast between the NPC engine-driven portable units (P/U range), weighing in at 30KG, and the portable electric Kranzle 1050p, which tips the scales at a mere 19 kg. Or, the Kranzle HD 7/122 that weighs just 22kg. 11kg lighter than the P/U, the Kranzle 1050p falls well in the carrying weight guidelines for men. Carrying the Kranzle 1050p or Kranzle HD 7/122 is notably lighter and more manageable task when compared to its engine-driven counterpart, the NPC P/U Range.

In practical terms, the reduced weight of electric pressure washers translates to increased manoeuvrability. Whether you’re navigating tight spaces or transporting the unit between locations, the lightweight nature of electric pressure washers proves to be a practical and user-friendly feature.

Brucey Bonus Benefit: #1 Quieter

Another advantage of electric pressure washers is their relatively quiet operation. The absence of an engine contributes to a noise reduction, making electric powered units more suitable for environments where noise levels are a consideration. Electric pressure washers typically fall within the range of 60-90dB, in contrast to engine-driven counterparts that average between 70-100dB. While the decibel difference may seem minor, it becomes more significant as the volume increases. The quieter noise output makes electric models an excellent choice for applications where noise reduction is a priority.

Brucey Bonus Benefit: #2 No Fuel

In addition to their operational efficiency, electric pressure washers offer a user-friendly feature by eliminating the need for liquid fuel or oil-fuel mixing commonly associated with 2-stroke engines. The simplicity of not having to worry about fuel not only streamlines the operating process but also reduces the risk of potential mishaps related to fuel handling.

Brucey Bonus Benefit: #3 Greener

Environmentally conscious consumers will appreciate the greener footprint of using electric pressure washers. With fewer emissions during operation, these models align with eco-friendly practices. Fewer emissions and the developing potential for renewable energy supplies makes them a more environmentally sustainable choice compared to their engine-driven counterparts. As businesses and individuals increasingly prioritise sustainability, the electric pressure washer range emerges as a responsible and conscientious option for cleaning needs.

Ensuring Water Safety: Understanding Water-Supply Separation Class 4 According to DIN EN 1717

In the realm of high-pressure cleaning equipment, maintaining the highest standards of water safety is paramount. One crucial aspect that plays a pivotal role in this is Water-Supply Separation, and when it comes to safeguarding against contamination, DIN EN 1717 class 4 stands as a robust measure.

What is Water-Supply Separation?

Water-Supply Separation is a system designed to prevent the unintended mixing of water used for industrial processes, such as in high-pressure cleaning equipment, with the water intended for human consumption. The goal is to uphold the purity and safety of drinking water by minimising the risk of pollutants entering the water supply.

DIN EN 1717 Class 4: Elevated Protection

Class 4 in DIN EN 1717 signifies a high level of protection. This rating emphasises the stringent measures in place to ensure that water used for industrial purposes remains entirely separate from the water meant for human consumption. The comprehensive safeguards implemented under class 4 are geared towards minimising any potential risks and maintaining the highest standards of water quality.

Why is it Important for Your Business?

For businesses involved in the use of high-pressure cleaning equipment, adhering to Water-Supply Separation standards is not just a regulatory requirement but a commitment to water safety. By following DIN EN 1717 class 4 guidelines, you contribute to the protection of the water supply, ensuring that the water used in industrial processes does not compromise the quality of drinking water.

Conclusion

Water-Supply Separation, especially when meeting the standards of DIN EN 1717 class 4, is a crucial element in maintaining water safety. By understanding and implementing these measures, we not only meet regulatory requirements but also contribute to the collective effort of ensuring clean and safe drinking water.

What are engine driven pressure washers?

Engine-driven pressure washers are simply pressure washers that use a combustion engine to operate their pumps. Similar to the way your car (assuming it’s not a swanky new electric model!) relies on an engine to propel the wheels, a pressure washer employs an engine to drive the pump and generate pressure.

Key Benefit: Portability & Remote Use Potential

The main advantage of engine-driven pressure washers is their portability and ability to be used just about anywhere (so long as you have a water supply!). They don’t need an electric power source, so as long as there’s water (e.g. water tank/bowser or IBC), they can be used anywhere. This makes them a top choice for mobile cleaning services like driveway, gutter, roof, and patio cleaning, as well as for mobile car valeting and detailing. They’re also widely used in the public sector, including local council cleaning services as many models can create enough pressure to deal with graffiti.

Brucey Bonus Benefit: Power

Another advantage of engine-driven pressure washers is their power. Regular 230V electric pressure washers might be limited in pressure and water flow, especially if your single-phase supply isn’t at its best. Take the Kranzle K2195, for example – it hits 180 BAR operating pressure, even overclocking to 195BAR (with a reduced flow rate/nozzle change below the standard 8LPM). Its cousin, the Kranzle K2160, is similar but focuses on creating more water flow (11 LPM) instead of higher pressure (140 BAR or 160 overpressure). These machines are really pushing the limits of a single-phase electrical supply. To go beyond this pressure or flow, you would need a three-phase supply, which can be expensive to install, often reaching tens of thousands. That’s why getting an engine-driven pressure washer is a more practical choice for those needing higher pressure and water flow rates.

Types of Engine Driven Pressure Washers

There are many types and forms of Engine Driven Pressure Washers. Below we will try to explore and present some options that we offer for each form of engine driven pressure washer. Here is a breakdown of the categories that we will discuss:

• Cold Water Mobile
• Hot Water Mobile
• Petrol/Gas Driven
• Diesel/Oil Driven
• Direct Drive
• Gearbox Drive
• Belt Drive

Cold Water Mobile

Our cold water mobile range is very popular, whether it’s electric or engine-driven pressure washers. Cold water pressure washers are typically more budget-friendly and, to be honest, typically far cheaper than hot water engine-driven pressure washers and still get the job done for most tasks. In the engine-driven lineup, cold water pressure washers are not only more affordable but also much lighter and smaller than their hot water counterparts.

As mentioned, our engine-driven range is a hit with mobile cleaning services. The cold water petrol powered Honda Range, usually sporting the powerful GX390 engine, rules this category by a long shot:

• Eco HR 20-21 (200 BAR; 21 LPM; Interpump)
• Eco HR 25-15 (250 BAR; 15 LPM; Interpump)
• Eco HR 25-15GB (250 BAR; 15 LPM; Gear-box driven; Interpump)
• Eco HR 25-15U (250 BAR; 15 LPM; Udor Pump)

Hot Water Mobile Pressure Washers / Steam Cleaners

For some, a crucial solution is our engine-driven hot water pressure washers. Here, the engine powers both the pump and heat coil, cranking out not just pressure and water flow, but hot water too. Among our choices, the top pick is the Ehrle HDD1240, known for its reliability and exceptional performance.

Fueled by a robust 10HP Yanmar Diesel Engine, the HDD1240 delivers a robust 180 BAR pressure with a flow rate of 15 LPM. Plus, it can heat water anywhere from 30 to 98°C, giving you the temperature you need.

Petrol/Gas Powered Pressure Washers

Petrol-powered (sometimes called gas) pressure washers run on petroleum/gasoline, the same fuel you fill your car with at a UK petrol station (usually the green pump). They tend to be lighter because petrol engines are naturally lighter than diesel engines. This makes them a go-to for folks who need maximum portability. Take the NPC Portable Unit, for example. Fueled by a Honda GX160, it can produce 150 BAR with either 8 LPM (P/U 15-08) or 11 LPM (P/U 15-11), all while tipping the scales at just 30kg.

There is also the Honda Range, mentioned earlier in the cold water pressure washers section, and the NPT range, rocking either the Honda GX 160 (NPT E2 15-11 or NPT 15-11) or GX 200 (NPT E2 15-13).

If you’re needing even more power then we also supply the NPC Twin Range, which features a twin cylinder Honda GX630 engine that can produce either 200 BAR at 30 LPM (WF HE 20-30) or 150 BAR at 42 LPM (WF HE 15-42).

Diesel/Oil Powered Pressure Washers

Diesel (sometimes called oil-powered) pressure washers are a handy cleaning solution. Although a bit heavier, they’re usually more cost-effective to run over the long term when compared to petrol-powered pressure washers, requiring less fuel for the same power output.

In addition to the diesel-powered Ehrle Hot Water HDD1240 we talked about earlier, we’ve got various diesel-powered cold water pressure washers. Check out our short-term hire, the belt-driven WF YE BD 20-15 (200 BAR; 15LPM; 1450 RPM). It’s a diesel-powered workhorse that’s tackled everything from stable cleaning to drain jetting, graffiti removal to truck washing. The wider NPC WF range more widely is a popular range of diesel pressure washer.

Direct Drive

Direct drive pressure washers have engines directly linked to the pump without extra parts like belts or gearboxes.

The perk of direct drive? No extra parts to pay for upfront or service/repair if they act up. The downside? The pump works at a higher RPM, wearing it out faster.

That’s why direct drive is common in domestic pressure washers. They’re not used as heavily as commercial or industrial ones, so the pump wear is limited. This saves money upfront, a big selling point. However, for folks planning to use their pressure washers extensively (100+ hours a year), we recommend gearboxes and belt drives. The initial savings on a gearbox can vanish quickly with additional pump servicing.

Many of our engine-driven ranges offer both direct and geared options. Quick tip: check the RPM on the spec charts. If it’s under 2000RPM, it’s likely geared drive. Above 2000RPM, it’s likely direct drive. Typically, direct drive engine-driven pressure washers need to run at over 3000 RPM.

Gearbox Drive

Engine-driven pressure washers can have gearboxes fitted between the engine and pump, cutting the engine’s drive, usually by about half, to the pump.

The plus side of gear drive? It lessens wear on the pump, a crucial part of any pressure washer, lowering service and maintenance costs.

Downsides? Upfront cost is the main one. Extra parts mean extra money. There’s also a potential risk if the gearbox fails. More parts, more chances for issues. However, from our experience, gearboxes need less upkeep than a non-gear-driven pump. That’s why we typically suggest gearbox drive for folks using their pressure washers a lot (100+ hours a year).

In our engine-driven lineup, you’ll find models with both direct and geared options. A handy tip: glance at the RPM on the spec charts. If it’s under 2000RPM, it’s probably geared drive. Above 2000RPM, it’s more likely to be direct drive. Just remember, direct drive engine-driven pressure washers typically need to operate at speeds exceeding 3000 RPM.

Belt Drive

Belt driven pressure washer operates similarly to gearbox drive but uses a belt instead of a gearbox to lower the RPM.

Belt drives reduce wear on the pump and can be more cost-effective upfront, as belts are cheaper than gearboxes. Though belts wear out faster than gearboxes, they’re more affordable to replace.

Identifying belt-driven pressure washers is simple – just check the specifications. Like with gearboxes, look for an RPM lower than 2000 (usually 1450RPM). Sometimes, as seen with the WF YE BD 20-15, the “BD” in the name indicates it’s belt-driven.

Close

In the dynamic world of high-pressure cleaning equipment, we’ve explored a spectrum of solutions tailored to diverse needs. From the popular cold water mobile range, with the mighty Honda GX390 engine leading the charge, to the robust and reliable Ehrle HDD1240 for hot water aficionados. We’ve navigated through the agility of petrol-powered options like the NPC Portable Unit and the practicality of diesel-driven workhorses exemplified by the WF YE BD 20-15.

Direct drives offer simplicity and cost-effectiveness for domestic users, while gear-driven models shine in reducing pump wear for commercial and industrial use. Belt drives, identified by their RPM specifications, emerge as another versatile and economical choice.

Inlet Water Flow and Preventing Cavitation: Why you must not starve your pressure washer of water

In the world of high-pressure cleaning equipment, maintaining the health of your pressure washer pump is paramount. One often underestimated but critical factor in achieving this is the proper management of inlet water flow. In this article, we will delve into the significance of maintaining adequate water flow and the potential dangers associated with cavitation.

The Basics of Inlet Water Flow:

Understanding the mechanics of a pressure washer pump is essential to grasp the importance of proper inlet water flow. Pressure washers utilise positive displacement pumps, designed to pump a specific amount of water continuously. When the rated amount of water is not provided, a vacuum is created within the pump, initiating a chain of events that can lead to severe damage.

Dangers of Cavitation:

Cavitation is a phenomenon that occurs when the pump is starved of water, leading to the formation of a vacuum and subsequent suction of air from any leaks in the system. This air, when drawn into the pump, causes cavitation, a destructive process with various detrimental effects.

1. Soft Component Damage:

Cavitation can rapidly deteriorate the pump’s soft components, such as seals and o-rings. These essential parts are crucial for maintaining the integrity of the pump and preventing water leakage.

2. Hard Component Damage:

Continued cavitation extends its impact to the pump’s hard components, including valve seats, connecting rods, and plungers. In severe cases, it can even result in the cracking of pump heads, rendering the pressure washer completely inoperable.

Preventing Cavitation:

To safeguard your pressure washer from the dangers of cavitation, several preventive measures should be taken:

1. Adequate Water Supply:

Ensure that the pump receives the rated amount of water to prevent the creation of a vacuum. Inlet plumbing, such as garden hoses, should be at least 1 1/2 times the size of the water inlet on the pump.

2. Leak-Free Plumbing:

Regularly inspect and maintain all plumbing components to eliminate leaks that could contribute to air being drawn into the pump.

3. Avoiding Restrictive Factors:

Factors like bends, turns, valve restrictions, and an excessively long inlet hose can impede water flow, leading to poor pump performance.

4. Proper Inlet Water Quality:

Ensure that the water supply is free from turbulence, and avoid using hot inlet water, as these conditions can negatively impact inlet water flow.

 

Inlet water flow is a fundamental aspect of maintaining a pressure washer’s pump in optimal condition. Understanding the dangers of cavitation and taking proactive measures to ensure proper water flow is essential for preventing unnecessary damage and extending the life of your pressure washer. By prioritising these considerations, you can enhance the efficiency and longevity of your high-pressure cleaning equipment, ultimately improving the overall performance of your business operations.

Power Supply Explained: Phase, Voltage and Hertz

Electrical specifications like “1 / 230V / 50Hz” or “3 / 400-415V / 50Hz” might seem complex, but they reveal crucial details about how your equipment operates. These numbers refer to phase, voltage, and hertz—the building blocks of any power supply. 

Understanding these elements ensures your machines run efficiently and prevents costly mistakes. Whether you’re powering small appliances or large industrial equipment, choosing the right power setup is critical.

In this article, we’ll break down phase, voltage, and Hertz using a simple analogy: traffic on a road. Just as cars move at different speeds and frequencies, electricity flows in specific ways. By the end, you’ll have a clear understanding of how to match the right power supply to your equipment.

Electrical Phases

When you see electrical specifications like “1 / 230V / 50Hz” or “3 / 400-415V / 50Hz,” the first number refers to the phase of the electrical system. “1” means the equipment runs on single-phase power, while “3” means it requires a three-phase power supply. But what exactly is the difference, and why does it matter?

What is Single-Phase Power?

In a single-phase system, electrical current flows through a single alternating current (AC) path. This setup is common in residential homes and smaller commercial spaces, as it efficiently powers everyday appliances.

Single-phase as a One-Lane Road

Imagine a single-phase system as a one-lane road. All the electricity moves along this one “lane,” just like cars driving down a quiet residential street. This road can handle regular household traffic—things like lights, small kitchen appliances, or a vacuum cleaner—because the power demand is relatively low.

Limitations of Single-Phase for Heavy Equipment

While simple and sufficient for most household tasks, single-phase systems aren’t ideal for heavy-duty equipment because the power delivered fluctuates, causing occasional peaks and drops. This makes it less suitable for machinery that requires a steady, constant power supply.

How Three-Phase Power Works?

A three-phase system distributes electricity through three alternating currents, each one staggered by 120 degrees. This stagger ensures that the power delivery is more constant and continuous, as the current from one phase reaches its peak while the others are still rising or falling. This coordinated, overlapping flow makes three-phase systems perfect for industrial or large commercial applications that need more consistent and higher power levels.

Three-Phase as a Three-Lane Motorway

Now think of a three-phase system as a three-lane motorway. Each lane represents a phase of electricity, and while the cars (or the electrical current) in each lane are moving at the same speed, they are spaced slightly apart from one another. This staggered timing allows for smooth, uninterrupted traffic flow, just like the continuous power delivery in a three-phase system. By spreading the load across three paths, the system can deliver more power without interruptions, reducing strain and increasing efficiency.

The Benefits of Continuous Flow for Heavy Equipment

For high-powered equipment—like large industrial machines or heavy-duty pressure washers—this constant, staggered flow is critical. It ensures that the power supply is smooth and uninterrupted, allowing equipment to operate efficiently without the fluctuations or power dips that can occur in single-phase systems.

Why Phase Matters

Choosing the right phase is crucial for your equipment’s performance. If your setup only supports single-phase power, it will be unable to handle machines designed for three-phase power without significant modifications. Similarly, using three-phase power for lightweight tasks may be unnecessary and inefficient. 

Matching Power to Your Equipment

For example, if you have a single-phase power supply, a machine like the Kranzle K1152 would be a good fit, as it’s designed for lower power needs. However, for heavier-duty machines like the Ehrle HD Series, which requires more stable and robust power, a three-phase supply is essential to ensure proper operation.

Voltage (V)

In the specifications “1 / 230V / 50Hz” or “3 / 400-415V / 50Hz,” the number followed by “V” (such as 230V or 400V) represents the voltage. But what does voltage actually mean?

Understanding Voltage as Electrical Force

Voltage is the measure of electrical potential difference, which can be thought of as the “force” or “speed” that drives electric current through wires. The higher the voltage, the faster and more forcefully electricity moves through the system.

Voltage as Speed in the Car Analogy

Imagine voltage as the speed of cars on a road. If the cars are moving slowly (low voltage), they might struggle to reach their destination in time to meet the demand. But if the cars are moving quickly (high voltage), they can get there faster and more efficiently. However, just as cars driving too fast on a narrow road can lead to accidents, using too much voltage can overload and damage electrical equipment.

Choosing the Right Voltage

The voltage specification of your machine tells you how fast the “traffic” (electricity) needs to flow. For example, a machine designed for 400V needs a faster flow of electricity to operate efficiently, much like a fast-moving car on a motorway. On the other hand, a 230V machine requires a slower, steadier flow, much like cars moving at residential speeds.

The Risks of Using the Wrong Voltage

Using the wrong voltage is like sending fast-moving cars (high voltage) down a narrow residential street—it’s risky and can cause damage. Similarly, using low voltage for a machine that needs high voltage is like sending slow-moving cars on a motorway—it won’t get the job done efficiently.

Voltage-Specific Products

• For 230V systems: Machines like the Ehrle KD623 pressure washer are ideal for use in residential or light commercial setups.
• For 400V systems: For more industrial applications, the Ehrle HSC1240 hot water pressure washer is designed to handle the higher voltage demands of heavy-duty equipment.

Hertz (Hz)

The final number in “1 / 230V / 50Hz” or “3 / 400-415V / 50Hz” represents Hertz (Hz), which measures the frequency of electrical current. In an alternating current (AC) system, electricity constantly changes direction, and Hertz tells us how many times this happens per second. For example, a power supply marked with “50Hz” means the current alternates direction 50 times every second.

Thinking of Hertz as Delivery Frequency

Think of Hertz as how often trucks make deliveries on a road. In a system running at 50Hz, a new truck loaded with electricity arrives 50 times every second, ensuring a regular and constant supply of power. Just like trucks arriving at regular intervals, the higher the Hertz, the more frequent the deliveries of electricity to your machines.

Why Hertz Matters

Hertz is crucial for maintaining a steady flow of power to your equipment. If the frequency is too low, it’s like having fewer trucks on the road, causing delays in deliveries and potentially underpowering your machines. If the frequency is too high, it might overload the system, leading to equipment malfunctions.

Global Hertz Standards

In most regions, such as Europe, electrical systems operate at 50Hz, meaning 50 deliveries (or cycles) of electricity are made per second. In places like North America, the standard is 60Hz. Using equipment designed for one frequency in a different system without adjustment can lead to issues. For example, a machine built for a 50Hz system used in a 60Hz environment might run faster than intended, while one designed for 60Hz may underperform in a 50Hz system.

Hertz-Specific Products:

• Standard 50Hz systems: Most of our machines, such as the Kranzle K1050 range pressure washer, are designed to work within the standard 50Hz frequency found in Europe (link to product).
• Higher performance needs: For heavier industrial tasks running on a 50Hz frequency, the Ehrle KD1340 cold water pressure washer provides reliable performance for larger commercial needs (link to product).

Making the Right Power Decisions

Understanding phase, voltage, and hertz is essential for ensuring that your equipment receives the right power supply. Like traffic on a road, electricity must flow smoothly, at the right speed, and with the proper frequency to keep machines running efficiently and safely.

Making Informed Equipment Choices

By knowing how single-phase and three-phase systems differ, why voltage matters for power capacity, and how Hertz ensures steady delivery, you can make informed decisions about the equipment you choose. Matching the correct power supply to your machines not only ensures optimal performance but also extends the life of your equipment.

The Impact of the Right Setup

Whether you’re running a small 230V system or managing high-demand machines on 400V three-phase power, the right setup makes all the difference. If you need help selecting the best pressure washer or industrial machine for your needs, feel free to get in touch with our team.

4. Flammability: Petrol is more flammable than diesel, posing a higher risk of fire in the event of a leak or accident. [Source: Argonne National Laboratory;]

Diesel

Diesel is a type of fuel that is also derived from crude oil. It is heavier but has a higher energy density than petrol. Diesel fuel is commonly used in diesel engines, such as those found in our NPC WF Range of engine-driven pressure washers. Diesel engines ignite the fuel through compression, unlike petrol engines that use a spark plug for ignition.

Advantages of Diesel:

1. Better Fuel Efficiency: Diesel engines are known for their higher thermal efficiency, resulting in better fuel efficiency and longer driving ranges.[Source: Byjus; Cazoo;]
2. Higher Torque: Diesel engines produce higher torque at lower RPMs, making them well-suited for heavy-duty applications like trucks and industrial equipment. [Source: Quora; Rentar;]
3. Lower CO2 Emissions: Diesel engines typically emit less CO2 per unit of energy produced compared to petrol engines, contributing to lower greenhouse gas emissions. [Source: youmatter; RAC;]
4. High Energy Content (to volume): Diesel has a higher energy content per litre compared to petrol, contributing to better fuel efficiency in certain applications. [Source: Quora;]

Disadvantages of Diesel:

1. Slower Ignition: Diesel engines have a longer ignition time compared to petrol engines, resulting in a slightly slower start and acceleration. [Source: Quora;]
2. Noise and Vibration: Diesel engines are generally noisier and produce more vibrations than petrol engines, affecting the driving experience. [Sources: Valvoline; Car Leasing Ltd.;]
3. Particulate Emissions: Diesel engines can produce higher levels of particulate matter, contributing to air pollution, although advancements in technology have led to cleaner diesel engines. [Source: youmatter; theengineer;]

Types of Diesel:

There are various types of diesel available, and it’s essential to ensure compatibility with the equipment we offer. (Please verify the compatibility of any fuel before using it in your cleaning equipment!) For instance, regular diesel is suitable for all our diesel-powered equipment. However, some equipment performs exceptionally well, or even better, with alternative diesel forms like kerosene/heating oils and bio-diesel. While regulations are increasingly stringent regarding red diesel, it’s worth noting that certain heating equipment, like the Airrex Heater Range, can still operate using it.

Regular Diesel

Regular diesel is the type of diesel you can get from the pump at the petrol station. It is, therefore, highly accessible. Most of the equipment that runs on diesel, will run on regular diesel.

Kerosene / Heating Oil: 

Kerosene is distilled from crude oil, burns hotter and holds more heat energy than many other types of diesel. This is advantageous in heating systems that are compatible with it as heat is the aim of the game!

Beyond greater heat output, Kerosene is also a good fuel option as it produces fewer emissions. It can often be cheaper (though like many fuels, this fluctuates) than other fuel types and is easier to light, with a lower flash point. 

The drawbacks of Kerosene include a contribution to carbon footprint/greenhouse gases, and it is also difficult to recycle.

At Idro Power we use a form of heating oil for many of our heaters and pressure washers, when working on them in-house. If you’d like to know more, get in touch via phone (01652) 659759, contact form (which links to our email) or facebook messenger.

Bio/Renewable-Diesel:

Biodiesel is an alternative fuel made from sources like vegetable oil, animal fats, or waste cooking oil through a process called transesterification. It serves as a renewable and more environmentally friendly substitute for conventional or fossil diesel.

Using biodiesel has environmental benefits, primarily being ‘carbon neutral’—it absorbs as much carbon during oil crop growth as it releases when burned. While there’s some pollution in biodiesel production, it’s rapidly biodegradable and non-toxic, reducing spillage risks. Biodiesel also has a higher flash point, making it safer in accidents. Overall, it’s a more environmentally friendly alternative to conventional diesel.

Understanding Weight: A Crucial Element in Cleaning Equipment

The equipment we sell comes in a range of weights. From portable lightweight pressure washers, to weighty statics, it’s important to bear weight in mind, especially if you intend to move or transport your equipment to  different places. For all of the pressure washers and heaters we sell, we aim to give the most accurate weight description that we can. We do this in kilograms. In this article we aim to discuss weight and kilograms, providing examples to illustrate its practical implications.

The Basics of Weight

Weight is a fundamental measure of the force exerted on an object due to gravity. In the realm of cleaning equipment, weight plays a pivotal role in determining the practicality and usability of devices like pressure washers. The weight of a machine can influence its manoeuvrability, transportability, and overall ease of use.

Weight and Pressure Washers or Heaters

The weight of a pressure washer can extend beyond mobility. In fact, it can be an insight into the performance and build quality of a pressure washer too. For example, while a lightweight model might be more portable and suitable for tasks that require frequent movement, a heavier unit could indicate a sturdier build and potentially higher pressure capabilities. Finding the right balance is essential, ensuring that the equipment is manageable without compromising on power.

A similar rule of thumb can be applied to heaters. Generally, size will lead to increased heating power. Just as a more powerful pressure washer pump increases in weight, so too do the parts of heaters, such as burners, exhausts and fuel tanks etc. Therefore, while a smaller heater can be portable, such as the DC61 or XL61 (17kW but 21kg), these will not be as powerful as similar style infrared heaters such as the Wilms Val-6 (40kW but 84kg*) or the XL91 (43kW but 85kg).

*The only weight given for the Wilms Val-6 is 50kg, which is with an empty fuel tank. We estimate that with a full tank that it would be about 34kg heavier, equalling 84kg.

Kilograms as the Unit of Choice

On our website, we exclusively use kilograms (KG, kg) as the unit of choice for weight measurement. Kilograms provide a standardised and precise way to communicate the weight of our cleaning and heating equipment, offering clarity for our diverse range of customers.

Examples for Clarity

Oil Fired Heaters: Understanding Heating Power in kW, BTU, and kcal

Heating power is a critical metric when it comes to evaluating the performance of heating equipment. In this comprehensive guide, we will delve into the units used to measure heating power—kilowatts (kW), British Thermal Units (BTU), and kilocalories (kcal)—and explore how this metric is employed in the specifications of the products we sell, leveraging the energy content of diesel as a benchmark.

1. Units of Measurement:

Kilowatts (kW), British Thermal Units (BTU) and Kilocalories (kcal). The specification charts on our sites do not always contain all of these three units of measuring power, but they typically contain one (usually kilowatts or british thermal units. Below is an explanation of each.

Kilowatts (kW):

Kilowatts (kW) are a unit of power commonly used to measure the heating capacity of appliances like heaters. In the context of heating equipment, kilowatts indicate the rate at which the device produces or consumes energy. For example, a heater with a higher kilowatt rating generally has a greater heating capacity, providing more warmth within a given time frame. Understanding the kilowatt rating is crucial when assessing the efficiency and effectiveness of heating equipment.

British Thermal Units (BTU):

When discussing heating power, British Thermal Units (BTUs) are a common unit of energy measurement, especially in the context of heating and cooling systems. A British Thermal Unit is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

 

In the realm of heating equipment, the BTU rating is used to quantify the heating capacity. For example, a heater with a higher BTU rating can produce more heat per unit of time, indicating a greater heating capacity. This measurement is essential for selecting the right heating equipment based on the specific heating needs of a space.

Kilocalories (kcal):

In the context of heating systems, a kilocalorie (kcal) is a unit of energy used to measure heating capacity. One kilocalorie is the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. When expressed in kilocalories per hour (kcal/h), it becomes a measure of the heating power or capacity of a heating appliance.

For instance, a heating system with a higher kilocalories per hour rating indicates a greater capacity to generate heat within a specific time frame. This measurement is essential for assessing the efficiency and effectiveness of heating equipment, helping users choose systems that meet their heating needs.

2. Diesel Energy & Specification “Heating Power”:

Many of our product specifications utilise the energy content of diesel as a basis for determining heating power (or, there or thereabouts at least). This approach allows for a standardised and consistent method of representing the heating capabilities of the equipment we sell.

Diesel and heating fuels such as kerosene, for instance, hold approximately 10-11 kW of energy per litre. In other words, if you burn one litre of diesel the energy output is 10kW. Therefore, a heater that burns 1 litre an hour would be rated as having heating power in the region of 10kW. Or, one that burned 5 litres per hour would be rated at about 50kW heating power.

(Source: https://www.sustainabilityexchange.ac.uk/files/cambridge_regional_college_sus_how_much_energy_do_you_use_pdf.pdf)

Master BV77 Example:

The Master BV77 heater, which consumes 2 litres of fuel per hour, boasts a heating power rating of 21 kW. Calculating the ratio of heating power to fuel consumption, we find that the diesel energy output per litre is 10.5 kW (21 kW divided by 2 litres). This calculation underscores the efficient utilisation of the energy content within the diesel fuel, resulting in the generation of 21 kilowatts of heating power. It highlights the effectiveness of the heater in converting fuel into a substantial and useful output for heating applications, making it a reliable and powerful tool in the realm of high-pressure cleaning equipment.

B230 Heater Example:

The Master B230 heater, with a fuel consumption rate of 6.2 litres per hour, showcases a remarkable heating power output of 65 kW. Through the calculation of the ratio between heating power and fuel consumption, the diesel energy output per litre is found to be approximately 10.48 kW (65 kW divided by 6.2 litres). This calculation serves to underscore the correlation between fuel consumption and the ensuing heating power, reinforcing the significance of diesel’s energy content as a benchmark. It exemplifies the efficiency of the B230 heater in harnessing the energy within diesel fuel, resulting in a robust heating capability. This emphasis on the relationship between fuel usage and heating power highlights the heater’s effectiveness in delivering substantial thermal output for applications in high-pressure cleaning equipment and reinforces its position as a powerful and reliable heating solution.

3. Considerations for Your Business:

A comprehensive understanding of heating power, particularly in the context of fuel consumption, is crucial for assessing the overall efficiency and performance of the heating apparatus. This knowledge empowers our customers, enabling them to make informed decisions tailored to their specific heating requirements. By grasping the interplay between heating power and fuel efficiency, customers can select equipment that not only meets their heating needs but also operates optimally, enhancing overall efficiency and performance in their applications.

How heating power helps with gauging efficiency and performance:

Heating power serves as a crucial and rapid indicator of a heater’s maximum heating potential and effectiveness. However, it’s essential to consider the type of heater and its method of heating the space. For instance, the heating potential of an air heater may be compromised if the heated air is lost or not distributed effectively. In the case of indirect air heaters, although the exhaust gas is flued away for fresh air, there is some heat loss with the exhaust fumes. 

When you consider these factors, the Airrex range stands out in terms of heating power/heating efficiency. As their efficient fuel combustion eliminates the need for flueing exhaust fumes. This ensures complete heat transfer for infrared heat. Consequently, the AH200i, AH300i, and AH800i are expected to closely align with their respective heating capacities of 13kW, 15kW, and 22kW, in theory.

Conclusion:

In the realm of high-pressure cleaning equipment, heating power is a key factor in ensuring the effectiveness of the equipment you provide. By comprehending the units of measurement, understanding practical examples like the Master BV77 and B230 heaters, and leveraging the energy content of diesel, your business can offer valuable insights to customers, promoting informed decision-making in their heating equipment investments.
