Baldor Motor for Commercial Use

At the heart of the HW255E3CNG is a 5.0 HP Baldor motor configured for three-phase power – the industrial standard for high-performance equipment. Built for continuous run times this energy efficient motor has the power for large scale cleaning while keeping the total cost of ownership low. Robust construction protects your investment by ensuring long term durability and reliability. The Baldor motor increases productivity by allowing for faster and more efficient cleaning so you can get the job done with less effort.

Benefits of the three-phase Baldor motor:

  • Lower operating costs over time

  • Smoother, more consistent power delivery

  • Lower heat output during extended use

  • Designed for commercial electrical systems

This motor is paired with the triplex pump and natural gas burner to make a true industrial grade cleaning solution.

Natural Gas Burner – Clean, Safe and Cost Effective

Perfect for indoor use the natural gas burner system plugs into your facility’s gas line using a Robertshaw valve eliminating the need for on-site diesel or kerosene storage. Hot water power washers like the HW255E3CNG can also use fuel oil or liquid propane as alternative heating sources for different industrial cleaning needs. This makes the HW255E3CNG a cleaner, safer choice for garages, warehouses, vehicle bays or service facilities where ventilation may be limited.

Cold water pressure washers are sufficient for removing dry, caked on dirt but are less effective at cleaning deep seated grease, grime and bacteria. Hot water breaks down tough contaminants much more efficiently making the cleaning process faster and more effective on any surface.With the adjustable thermostat you can set the water temperature up to 93°C / 200°F for high-heat degreasing or sanitizing. The heavy-duty heating coil is made from 1/2” schedule 80 carbon steel with a stainless steel wrap for long term heat transfer and corrosion resistance. The heat enhances the cleaning process allowing for fast removal of buildup from surfaces.

AR Triplex Pump for Commercial Use

The AR triplex pump on the HW255E3CNG is designed for continuous-duty operation and maximum service life. Built to the same quality as top industrial systems it can handle any cleaning job from light residential to heavy-duty commercial. It includes:

  • Forged brass manifold for strength and corrosion resistance

  • Solid ceramic plungers for high temperature and extended pump life

  • Stainless steel check valves for consistent flow and pressure

  • Thermal relief valve to prevent overheating during extended use

An external unloader valve helps to dissipate heat more effectively than internal unloaders allowing for easier maintenance and better performance – a big advantage for service technicians and operators.

Auto Start/Stop for Efficiency and Longevity

The auto start/stop system enhances safety and reduces wear by turning the pump only when the trigger on the spray wand is pulled. When the trigger is released the pump shuts off after a short delay conserving energy and reducing wear on the components. This also simplifies the cleaning process for the operator by eliminating unnecessary steps and making it more intuitive.

Benefits include:

  • Reduced heat buildup in the pump and motor

  • Lower water and electrical consumption

  • Quieter operation between uses

  • Ideal for multi-operator facilities or shared workspaces

  • Users can find the optimal settings for their cleaning needs

This feature is especially useful in applications where the washer is used intermittently throughout the day.

Built to Last Daily Use

From the powder-coated steel frame to the stainless-wrapped heating coil every component of the HW255E3CNG is built to last. The compact roll cage frame protects the vital parts from impact and provides clear access for inspection and service. A built-in lift point allows for easy transport by crane or forklift – perfect for truck mounted or stationary applications.As a hot water pressure washer leader the HW255E3CNG delivers performance for tough environments. Whether you’re cleaning trucks in a fleet yard, equipment in a factory or vehicles in an indoor garage this unit is built to keep working.

Professional Grade Accessories Included

Frequently Asked Questions about Pressure Washers

How to store a pressure washer?

To ensure the durability of your heavy duty pressure washer:

  • Empty the gas tank to prevent fuel from degrading or clogging the engine.
  • Empty the pump and hoses of any remaining water.
  • Perform necessary maintenance before storage.
  • Store in a dry area.
  • Cover.

What is a pressure washer?

A power washer is a cleaning machine that uses a gasoline engine to power a high pressure water pump and nozzle. It’s used to clean driveways, decks, vehicles, outdoor furniture and more by spraying water at high PSI to remove dirt, grime, mold and other debris.Many models also come with a detergent tank for added cleaning power.

How does a power washer work?

A power washer works by drawing water from a connected hose and pumping it through a high pressure nozzle. The gas engine powers the pump which pressurizes the water and then expels it through the nozzle at high speed to clean the surface. The water pressure is measured in PSI (pounds per square inch) and the flow rate is measured in GPM (gallons per minute).Many models also feature adjustable water pressure settings to cater to different cleaning needs. BE makes pressure washing easy with models available for light jobs and heavy duty commercial cleaning projects.

Gas vs Electric power washers?

The main difference is that a gas pressure washer, known for its cleaning power, is powered by a gasoline engine, making it more powerful and portable, while an electric pressure washer is powered by electricity and is generally quieter and lighter.

Gas pressure washers are for heavy duty and large areas due to their durability, whereas electric pressure washers are for smaller jobs.

Your BE electric pressure washer is perfect for smaller jobs and built for portability, and we offer a wide range of electric models. Included with our electric models is a long extension cord for use anywhere around your house.

What to consider?

When choosing a gas pressure washer consider:

  • Pressure (PSI): More PSI means more cleaning power but also more potential for damaging delicate surfaces.
  • Flow Rate (GPM): More GPM means faster cleaning as more water is dispensed.
  • Engine Power: Bigger engines mean more durability and power.
  • Portability: Weight, handle design and wheel size for easier to move.
  • Nozzles: Multiple spray nozzles to adjust the spray pattern for different tasks.
  • Adjustable Nozzle: Allows for fine-tuning the spray intensity and pattern for various cleaning needs.

How much pressure do I need for?

The required pressure (PSI) and cleaning power depend on the surface you’re cleaning:

  • Light duty (car washing, outdoor furniture): 1,300-1,800 PSI.
  • Medium duty (patios, fences, decks): 2,000-3,000 PSI.
  • Heavy duty (driveways, brick walls, large equipment): 3,000+ PSI.

Many pressure washers come with adjustable pressure settings to handle different cleaning tasks effectively.

Can a pressure washing damage surfaces?

Yes, a power washer can damage surfaces if used incorrectly. High pressure water can strip paint, dent soft surfaces or even cause structural damage if the pressure is too high or the nozzle is held too close to the surface. Always use the right PSI for the material you’re cleaning and keep a safe distance from delicate surfaces.

To prevent damage, consider using a model with adjustable pressure settings.

How to maintain your pressure washer?

To ensure the durability and smooth operation of a pressure washer:

  • Change the oil as per manufacturer’s instructions.
  • Clean or replace the air filter to ensure good airflow.
  • Inspect and clean the nozzle regularly to prevent clogs.
  • Drain the gas tank if you’re storing the washer for a long time.
  • Check the hoses for leaks or damage and replace them if needed.
  • Follow regular maintenance requirements to keep the washer in optimal condition.

Can I use a pressure washer in cold weather and low water temperature?

You can use a pressure washer in cold weather but it’s more difficult. The water flow rate in the hoses and pump can freeze and damage the equipment. If you plan to use your pressure washer in cold temperatures make sure to winterize it and store it in a warm area when not in use. You can also use anti-freeze solutions for pressure washers.

Some models are designed to use hot water, which can be particularly effective for cleaning in cold weather.
