Kärcher has introduced a new line of self-contained, skid-mounted, electric-powered and diesel-heated hot-water pressure washers as part of the Liberty Series. There are five models with cleaning power ranging from 4.2 to 4.8 gpm (gallons per minute) and 2000 to 3000 psi (pounds per
square inch) of pressure. All five are encased in a steel cage made of 1-1/4-in. steel tubing and painted with an epoxy powder coat finish for all-weather protection.

These skid units are powered by an industrial-grade motor and have a variety of electrical configurations, including 230V and 460V both single and triple phase. All feature a belt-drive, high-pressure pump with five-year warranty. Both the motor and pump are isolated from the rest of the
machine on a shock-mounted sub-frame to reduce vibration.

Other features of this line of hot-water pressure washers include: spring-loaded, insulated trigger gun with insulated wand; high-pressure detergent injection system; 50 ft of wire-braid hose rated for up to 4500 psi; and 9-gal polyethylene fuel tank.
