Couldn't load pickup availability
The Hotsy 5700/5800 Series is a stationary hot-water pressure washer for wash bays, fleet shops and industrial plants. A 20 HP electric motor drives a large-frame Hotsy belt-drive triplex pump, and an upright gas-fired coil delivers 8.0 to 9.5 GPM of heated water for cutting grease, mud and road grime off trucks, heavy equipment and machinery. It is remote-ready, so it can sit in a mechanical room and serve the bay from a wall station.
Features
- 20 HP three-phase electric motor on slide-out rails for easy removal
- Hotsy belt-drive triplex pump with NESTechnology U-seals, rated by Hotsy for about 3× longer pump life
- Upright vertical coil holds a steady temperature; stainless steel coil skin stands up to overspray
- Programmable Smart Control relay: auto start/stop, run-time control and time-delay shutdown
- Adjustable upstream detergent injection for high-pressure soap
- Elevated gas valve at the back corner, kept clear of water and easy to plumb
- Burner assembly pivots down for access to the burner ring and pilot
- Pressure relief valve protects against thermal expansion
- Side and front panels lift off for service
