The Kranzle Therm 635-1 is a solid and very well made oil heated single phase mobile pressure washer for industrial applications. Special design of the burner system ensures that the flame never touches the coil, eliminating sooting problems and reducing servicing costs. A digital flame monitor stops fuel flow in the event of a flame failure to prevent the build-up of unburnt fuel in the heater for added safety. Supplied with Gun, Lance and High Pressure Hose.
