Diesel-Powered Hot Water Pressure Washers

Cam Spray’s heavy-duty diesel-powered heated pressure washers are portable, high-powered options that do not require an electrical plug-in source. Our high-performance industrial heated pressure washers use diesel engines to not only drive the pump, but also to allow the high amp charging system to provide power to the 12 volt DC power to keep the battery charged and burner system operational. Other features:
  • Industrial Hatz® diesel engine
  • Triplex plunger pump with ceramic plunger and stainless steel valve
  • Low-pressure chemical injectors
  • Protected by unloader valve and secondary pressure pop off valves
  • Burner system includes a rust-free fuel tank and schedule 80 coil with stainless steel wrap
  • Adjustable thermostat and temperature limit switch
  • Maximum temperature of 195°F
  • Heavy-duty trigger gun with dual wand and side handle valve
  • Equipped with quick change 0°, 15°, 25°, and 40° nozzles

Note: A Group 24 battery is not included but is available at any local auto parts store. All hot water high-pressure cleaners that burn or use fuel should only be operated outdoors or in a properly ventilated area. Contact Cam Spray to learn more.
