Hydro Tek HN Series

Stationary, Electric Powered, Natural Gas, LP or Diesel Heated

General Details

Made in the USA for industrial use, the HN Series is a stationary hot water pressure washer that is powered by electricity and heated by your choice of natural gas, propane or diesel. This allows you to install indoors and have hot water on demand in your wash bay at your facility. These models include stainless steel panels, industrial duty motors and pumps and a lifetime heating coil warranty.


Ready to work when you are: No need to fill fuel tanks or hunt down a water supply when machine is directly plumbed into natural gas and water lines. The pressure washer can be housed indoors, away from the elements, while installing wash stations remotely outdoors.

Clean and Efficient Heating System: 24v automatic, electronic ignition on low emission natural gas burner. Liquid Propane conversion option or diesel heated option is available on any model.

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. Ask your dealer about the Lifetime Coil Warranty.

Belt Driven Pump: Low RPM drive – cooler, quieter, continuous duty performance. These industrial triplex pumps feature ceramic plungers for long life. EZ Align™ pump rail system for belt tensioning with a simple adjustment

NEMA4 Water Tight Electrical Box: ETL certified to UL1776 Class 2 for use in wash-down area, exceeds industry standards. Special Hydro Tek control box features easy to use controls and provides instant access to electronics. Standard
diagnostic indicators ensure optimal system performance. Dual voltage switch on most 230v models allows you to simply flip a switch to change to 208v power supply.

Bypass Cool System: Worry free pump cooling system prevents pump from overheating with system designed pump bypass feature.
