115 volt, 8-10 GPM Diesel Fired Hot Box - 99115V

Turn Cold Water Pressure Washers into Hot Water Beasts The BE Power Equipment 99115V Vertical Electric-Ignition Diesel-Fired Hot Box is built for professionals who need serious hot water performance without investing in a full hot water pressure washer. Designed to connect directly to an existing cold water pressure washer, the 99115V instantly upgrades your system with industrial-grade heat for faster, more effective cleaning. Engineered for high-flow applications, this hot box supports 8.0–10.0 GPM, making it ideal for large-volume washing where heat and water flow work together to break down grease, oil, and heavy buildup. Powered by 115VAC and delivering 420,000 BTU, the 99115V heats water up to 93°C / 200°F, dramatically improving cleaning efficiency while reducing detergent usage. Built into a rugged powder-coated steel frame, this vertical hot box is designed to withstand demanding job sites while providing reliable, on-demand hot water whenever the job calls for it. Add Industrial Heat to High-Flow Pressure Washers The 99115V is purpose-built for professionals running higher-GPM cold water systems and is ideal for: Fleet and heavy equipment washing Agricultural and farm equipment cleaning Industrial wash bays Property maintenance and sanitation Construction and transportation applications By introducing heat into the cleaning process, operators can clean faster, cut through grease more effectively, and minimize chemical use. Features High-Output Diesel-Fired Heating System At the core of the 99115V is an SM diesel burner with electronic ignition, delivering consistent and reliable heat for demanding cleaning environments. Heating system highlights include: 420,000 BTU output Maximum water temperature of 93°C / 200°F 115VAC operation Toggle burner on/off switch Inline fuel filter for burner protection This system delivers dependable heat for high-flow pressure washing applications. Heavy-Duty Heating Coil Assembly The 99115V features a 260’ x 1/2” Schedule 80 cold-rolled steel heating coil, designed to handle higher flow rates while maintaining efficient heat transfer. Schedule 80 construction resists pressure and thermal stress Extended coil length supports 8.0–10.0 GPM operation Built for long service life in industrial environments Integrated Safety and Flow Protection This hot box is equipped with multiple safety systems to ensure dependable and controlled operation: Flow switch to monitor water movement High limit switch to prevent overheating Rupture disk for pressure protection Toggle burner switch for operator control These features protect both the hot box and the connected pressure washer during use. Extended Runtime Fuel Capacity A 7-gallon (26.5 L) black poly diesel fuel tank provides extended operating time, allowing operators to work longer between refueling.
