Marse – Water flow regulators (WFR / RWFR / EWFR)
The Marse water-flow regulator range measures and controls cooling-water flow per circuit in the cooling channels of an injection moulding tool. From the simple WFR through the electronic EWFR to the high-temperature RWFR series, every requirement is covered. The electronic EWFR provides real-time data logging and alarms when any circuit deviates – preventing scrap from forming.
