The Hotsy HSS-503069E Super Skid Hot Water Pressure Washer is a heavy-duty industrial cleaning system engineered for the most demanding applications. Part of Hotsy’s Super Skid HSS and HSDS series, this model represents the largest and most powerful hot water pressure washers in Hotsy’s lineup, designed specifically for trailer-mounted, continuous-duty operation.
Built to handle extreme cleaning environments, the HSS-503069E delivers up to 5.0 GPM at 3,000 PSI, with the capability to scale within the Super Skid platform to higher flow or pressure configurations. At the core of the system is a reliable Hotsy Triplex belt-drive pump, delivering smooth performance and long service life for industrial operations.
Power comes from a Kubota diesel engine with electric start, paired with a high-efficiency Wayne 12VDC burner for consistent hot water output. The unit features a 3/4-inch foil-backed insulated Schedule 80 heating coil with stainless steel skin, backed by a 5-year warranty, ensuring durability, heat retention, and corrosion resistance.
Designed for extended run times, the HSS-503069E includes dual fuel tanks with a combined 50-gallon capacity, reducing downtime on large jobs. A high-flow industrial unloader and ten vibration isolators between the platform and frame help maintain consistent pressure while protecting components during transport and operation.
This Super Skid system is built for flexibility, with optional upgrades including a dual-gun kit for two-operator use, a float tank and high-pressure detergent kit for constant pressure delivery, and an optional steam combination control kit for added cleaning versatility.
