The wear-free nozzle is equipped with a valve specially developed by acp for this purpose which enables pulse times as fast as 20 milliseconds. In contrast with pilot-operated standard valves, the direct control of the valve prevents icing and thus ensures reliable operation and consistently superior results. The jet and pause times can be set independently of each other, so that the pulses can be optimally adapted to the respective application and also to the part-specific cleaning sequence. At the same time, the pulsed jet reduces CO2 and compressed air consumption. Depending on the pulse time, savings between 10 and 15 percent can be achieved.
