All-electric hot-Krcher Commercial, Camas, Wash.pressure washers generate instant hot-water spray with a pull of the trigger and without any open flame or hazardous fumes from combustible fuels. Two models offer 3.5 to 4.2 gpm and from 2,000 to 3,000 psi on three-phase electrical power of 460 volts. Water is heated in a stainless-steel coil submerged in a tank of water solution that is designed to efficiently transfer heat. A layer of oil on water’s surface retains heat and reduces evaporation. Low-water protection prevents damage to nine 4,500-kW heating elements should water level drop too low. Tri-plunger, high-pressure pump accepts water up to 180 F. Both motor and pump are mounted on a platform with four vibration isolators to minimize stress on frame. ETL certified to UL and CSA safety standards.
