Upgrade your cold water pressure washer with powerful hot water performance using this diesel-fired hot box. Designed to connect directly to existing systems, it converts cold water setups into effective hot water cleaning solutions for removing grease, oil, grime, and heavy buildup.
Powered by 12VDC, this unit is ideal for mobile setups including truck-mounted and trailer-mounted systems, as well as remote job sites. A high-output diesel burner delivers up to 550,000 BTU, heating water up to 200°F (93°C) for faster cleaning and reduced chemical use.
Built with a rugged powder-coated steel frame, the vertical design provides a compact footprint while protecting internal components. It's engineered for reliable, on-demand hot water in demanding commercial and industrial environments.
The system features a heavy-duty Schedule 80 black pipe heating coil with a stainless steel coil wrap designed for efficient heat transfer and long service life. Integrated controls such as an ST7 flow switch, a PAC inline thermostat, and a rupture disk help ensure safe and consistent operation.
A large 7-gallon diesel fuel tank allows for extended runtime, making it well-suited for longer cleaning sessions without frequent refueling.
