rJET DN25s 2x4 LH 1

Item number: 001 460

Return utilization

For highly efficient use of the return flow of an unmixed high temperature circuit in a mixed low temperature circuit by means of highly efficient operation of a system separation via flow control from the differential pressure of the pump in the heat generator circuit (i.e. without an additional pump in the primary circuit of the system separation!) at a condensing boiler, a stratified storage tank or a heat transfer station
