The Hotsy 1200-Series includes eight models of self-contained, gasoline-powered (either Honda or Briggs & Stratton Vanguard), hot-water pressure washers that feature an integral roll cage that secures the heating coil and helps protect the machine. All models use a diesel-fueled burner to heat water, and flow volumes and operating pressures range from 4.3 to 5.6 gpm, and from 3,000 to 4,000 psi. The 1200-Series models are designed for mounting in a pickup truck or on a trailer to work in conjunction with a water tank for added portability.
