SS Series Mobile Wash Skid – 5.5GPM Steam / Hot / Cold Water Pressure Washer

The SS Series Mobile Wash Skid is a self-contained steam, hot, and cold water pressure washer engineered for heavy-duty, mobile cleaning applications. Powered by a gas engine with a diesel-fired 12V burner, this system delivers continuous hot water without the need for external electrical power.

Using the engine’s 12-volt charging system to power the diesel burner, the SS Series provides reliable, high-temperature cleaning in a compact, easy-to-maintain design. Its slim footprint allows it to pass through standard commercial doorways, while multiple mounting options make it one of the most versatile mobile wash skids available.

Simply turn the key and start cleaning with professional-grade pressure and heat—anywhere the job takes you.

Ideal for property management companies, farmers, mechanics, fleet operators, construction crews, and industrial users who need a powerful, mobile solution for removing dirt, grease, oil, and grime.
