Traditional high-pressure cleaners are ordinarily equipped with an injector for induction of detergents. In order to suck in the detergents, the water, which is under high pressure, needs to be pressed through a small nozzle pipe. This costs energy, no matter if the injector is in operation or not. The available working pressure is reduced by approx. 30 %.
Kränzle high-pressure cleaners with water tank are designed such as to allow the pump to suck up water from the water tank as well as detergents at the same time. The energy consuming injector and the simultaneous loss of efficiency and/or pressure of up to 30% is eliminated. The detergents can be sprayed without reducing the operating pressure.
