The Hotsy HSS & HSDS Series pressure washers are built for demanding hot water cleaning where high flow, long runtimes, and a skid-mounted setup make sense. Eight configurations range from 5.0 to 9.5 GPM and 2,500 to 3,500 PSI, giving heavy equipment, fleet, industrial, and remote cleaning operations several output options.
The HSS-503069E delivers 5.0 GPM at 3,000 PSI using a 599cc Kubota Z602-E4B diesel engine with electric start. Its belt-drive system powers a Hotsy HX5843R.2 triplex pump, while a 12V DC Wayne oil burner delivers 465,000 BTU/hr through a 3/4-inch Schedule 80 steel heating coil. Larger models use the 1123cc Kubota D1105-E4B diesel engine and step up to as much as 9.5 GPM.
HSS & HSDS Series Models
The skid-mounted diesel hot water pressure washer design is built around a square-tube frame with removable supports. The HSS-503069E includes dual 25-gallon diesel tanks, a fuel/water separator, key ignition, volt meter, hour meter, adjustable thermostat, high-flow unloader, pressure-relief safety valve, and 50 feet of two-wire high-pressure hose.
