Why add a Hot Box

If you already own a good cold machine, a Hot Box is the economical path to hot water work - no need to replace the pump, engine, or rig you have. It also lets fleet operations heat multiple stations from portable modules.

12V diesel-fired burner - runs off your rig's battery and diesel
Modular - skid, truck, or stationary mounting
Serviceable - coils, burners, and parts stocked in Georgia

See burner parts and replacement coils for service items, or compare complete hot water pressure washers.

Frequently asked questions

Will a Hot Box work with any pressure washer? It needs to be matched to your machine's GPM and PSI range - tell us what you run and we will confirm the right HB model.

How hot does the water get? Working temperature depends on flow; lower GPM through the coil yields higher temperature rise. Our engineers can spec the output for your setup.
