All-Electric Hot Water Pressure Washer - Alfred Karcher Inc.

Oct. 26, 2007
Kärcher  has introduced a new all-electric hot water pressure washer ideal for indoor cleaning.This new line of pressure washers generate instant hot water spray with the pull of the trigger and does so without an open flame or hazardous fumes typically associated with hot water pressure washers, most of which heat with combustible fuels. It runs so quietly it can be installed inside a closet or under a stairway. There are two models in the series with cleaning power ranging from 3.5 to 4.2 GPM (gallons per minute) and from 2,000 to 3,000 PSI (pounds per square inch) of pressure. Both models operate on electrical power of 460-volt, 3-phase.The water is heated in a stainless steel coil submerged in a tank containing a special water solution designed to produce highly efficient heat transfer. A layer of oil rests on the surface of the water solution for optimum retention of heat and to reduce  evaporation. Low-water protection prevents damage to the nine 4500KW heating elements should the water level in the tank drop too low.Both models feature Kärcher's belt-drive, industrial-duty, tri-plunger, high-pressure pump that can accept water at up to 180°F and carries a 7-year warranty. The pump is housed in a painted steel cabinet and is connected to an industrial-strength motor via a rugged assembly consisting of two V-cogged belts and cast-iron pulleys for years of reliability. The belts are tightened using an innovative two-bolt pulley adjustment system.Other features include:o Motor and pump are mounted on a power platform resting on four vibration isolators to minimize fatigue and stress on the frame;o Automatic start/stop which allows the unit to be turned on with the pull of the trigger for operator convenience and protection;o Spring-loaded, insulated trigger gun with variable pressure wand for remote operation of the spray, plus remote application of the soap;o Detergent injection systemo ETL certification to both UL and CSA safety standards.
