HP Series: Hot Water Pressure Washer - Portable Electric, Diesel Heated with Exceptional Heat Output

HP Series: Hot Water Pressure Washer - Portable Electric, Diesel Heated with Exceptional Heat Output


The portable HP Series hot water pressure washer delivers a balance of pressure, water flow and heat required for the fastest cleaning. A side-by-side demonstration will show that cleaning performance is determined more by the combination of water, heat and flow, not just pressure. The HP Series hot water pressure washer has the high capacity burner to accommodate high water flow and achieves a higher temperature rise than other washers and saves valuable time and effort. To save you even more time, it features auto on/off, remote downstream soap control and adjustable pressure, giving the operator control at the spray gun and saving pump components and wear. It even has full pressure steam setting to clean faster on heavy equipment, greasy floors, dirty walls, oily steel or any grime-ridden surface.


High Heat / High Flow System:
The balance of heat and flow increases your cleaning power providing a consistent superior performance. Auto ignition for peace of mind & ease of operation. High capacity diesel burner with higher temperature rise for faster cleaning.

SpiraLast™ Coil:
The coil is a Hydro Tek manufactured SpiraLast™ heating coil. Robotically fused ½” schedule 80 steel pipe is cold rolled to protect the steel pipe from fatigue and the spiral coil is then surrounded by ceramic insulation and stainless enclosure with double-wall end caps. Check out our lifetime coil warranty.

Auto Start and Time Delay Shutdown:
With HP Series Hot Water Pressure Washers the operator has total control over the system from the trigger gun. This added convenience not only saves time and effort, it reduces wear and overheating of the pump and produces an energy efficient system that outperforms the traditional manual on/off.

Stainless Steel Coil Housing, Frame and Panels:
Rust-proof durable panels offer corrosion resistance and protection of your valuable investment from the harshest environments. Keeps your machine looking like new for years to come. Screw connects provide easy removal for full access to all major components and the ultimate in serviceability.

Adjustable Temperature with Steam Setting:
Front mounted controls allows quick and easy adjustments of temperature and steam settings with higher heat than comparable washers for your toughest cleaning applications.

NEMA4 – Water Tight Control Panel:
ETL certified to UL1776 Class 2, for use in wash-down area, exceeding Industry standards. Special Hydro Tek control box features easy to use controls and provides instant access to electronics. Dual voltage switch on most 230v models allows you to simply flip a switch to change to 208v power supply.

CAT Direct Drive Pump:
High torque, low RPM drive – cooler, quieter, continuous duty performance. These Industrial triplex pumps outperform the competition in longevity – featuring concentrically bored & polished, graphite impregnated ceramic plungers with advanced seal design.

Diesel Fuel Tank with filtration:
Heavy Duty “roto-molded” rust free fuel tank with water separating fuel filter to protect against contaminated fuel. Extended run time (up to 5 hrs) eliminates interruptions.

Chemical Injection:
Equipped with inlet soap injection combined with precision chemical metering valve and float tank to inject soap at full pressure for optimal cleaning effectiveness. Panel mounted controls enable the operator to vary the mixture of soap or other additives with ease.

  • Advantages of a Hot Water Pressure Washer

    Simply by heating up the water, a hot water pressure washer delivers dramatically improved cleaning power compared to a cold water machine. Hot water pressure washers are especially useful for cleaning sticky, greasy, or oily surfaces, because they will loosen the dirt much faster without the large amounts of soap, detergent, or other cleaning chemicals that must be used with a cold water system.

  • Hot Water Pressure Washer Applications

    A hot water pressure washer is essential for any cleanup job involving a sticky, greasy, or oily mess, as well as for applications where a surface must be sanitized. With a variety of models available, including self-contained mobile units with gas, diesel, or electric power, Hydro Tek hot water pressure washers can go anywhere and clean anything. Some common applications include heavy equipment cleaning, vehicle cleaning, graffiti removal, restaurant hood vent cleaning, and livestock facility cleaning.

Quality & Innovation Since 1985

Hydro Tek

From simple beginnings in 1985, Hydro Tek has grown to become the most trusted name in the pressure washer manufacturing industry.

How did we do it? By continually focusing on quality and reliability as the key to customer satisfaction, and by incorporating the latest technologies into our design and manufacturing processes.

By 1991, we were using computer-aided drafting systems to refine our product designs and improve efficiency. In 1997, we brought the power of computers to the shop floor by incorporating laser-cutting and other CNC manufacturing machinery, and in 2001 we began focusing on improving efficiency through the latest manufacturing techniques. The end result has been superior products delivered at a superior value to our customers. Through the next decade, we look forward to fulfilling our vision of making our products the "obvious choice" for all your industrial and commercial cleaning needs.
