DESCRIPTION

Extreme Flow Meets Unmatched Durability — Built for the Pros Who Work Harder

For commercial cleaning professionals who face the toughest grime, biggest messes, and tightest deadlines, the BE Power Equipment HW3524HA12V delivers unstoppable cleaning performance. Pushing out a massive 3,500 PSI at 8.5 GPM, this hot water pressure washer pairs high flow volume with the heat you need to blast away grease, oil, and buildup—fast.

At the heart of the machine is a Honda GX690 V-Twin engine with electric start, matched with a belt-driven AR triplex pump known for industrial reliability. A 12V Beckett diesel burner powers a heating coil capable of reaching up to 200°F, and the entire system is framed in a rugged powder-coated steel roll cage—ready for permanent truck or trailer mounting.

This is the pressure washer serious pros rely on when clean matters and downtime isn’t an option.

Power + Heat + Volume = Unrivaled Cleaning Performance

When you're working in heavy equipment yards, sanitation zones, or construction sites, standard washers just can’t keep up. The HW3524HA12V was engineered specifically for high-output environments, offering a rare combination of 3,500 PSI and 8.5 GPM—ideal for large surface areas, heavy debris, and high-throughput commercial workflows.

The 12V diesel-fired Beckett burner fires up a high-efficiency heating coil to produce hot water up to 200°F (93°C). The result? Cut through grease, oil, and stuck-on gunk in half the time. And with the adjustable thermostat and rocker switch burner control, you can quickly adapt to hot or cold water jobs.

Honda GX690: The Trusted Name in Industrial Engines

The powerplant of this unit is the Honda GX690 4-stroke V-Twin engine, known across industries for its smooth performance, low fuel consumption, and long operating life. It's engineered for durability with cast-iron cylinder sleeves, OHV design, and a high-output charging system—perfect for continuous-duty applications in the field.

Electric start functionality ensures hassle-free ignition at the push of a button. Included is a 55AH marine-grade AGM battery, built to withstand harsh jobsite conditions, vibration, and extended use.

Belt Drive System: Quiet, Efficient, Built to Last

This model features a belt drive system, reducing the pump’s RPM and operational stress to significantly extend its lifespan. Lower heat and vibration levels also translate to quieter, smoother operation, ideal for all-day jobs or in areas where consistent performance is critical.

Belt-driven pumps are the gold standard in high-use commercial environments—and this one is no exception.

Industrial AR Triplex Pump: Built for Real Work

The AR (Annovi Reverberi) industrial-grade triplex pump is built to withstand years of high-pressure operation and exposure to hot water. It’s engineered with premium materials and smart design to keep working long after others give out:

  • Reinforced pump body for maximum durability

  • Forged brass manifold resists corrosion and heat damage

  • Solid ceramic plungers reduce wear, even in high-temp cleaning

  • Stainless steel check valves for precision control and pressure retention

  • Thermal relief valve prevents overheating and protects internal components

Paired with an external unloader, the pump runs cooler and more efficiently, giving you the performance edge and long service life your business depends on.

Purpose-Built for Truck & Trailer Mounting

The 1.5” OD powder-coated steel roll cage is designed to be bolted directly to trucks, trailers, or custom skids. It protects critical components from the elements and rough handling, while leaving everything accessible for operation and maintenance.

This frame isn't just rugged—it's smart. With its compact footprint, centralized lifting point, and modular mounting brackets, it’s perfect for permanent installations in service rigs, utility trailers, or mobile wash trucks.

Smart Maintenance Features for Less Downtime

Routine maintenance shouldn’t slow you down. This unit includes dedicated oil drain hoses on both the engine and the pump, making oil changes easier, faster, and cleaner without crawling under the frame.

These small details save time—and in high-volume operations, that adds up fast.

Industrial-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.
