Based around the compact reliable and highly efficient Vahterus Plate & Shell Heat exchanger (PSHE) the C4S-CHRM has been designed to recover the excess heat in a pressurised condensate return line. Transferring the recovered energy into the boiler feedwater on its journey from the feedtank to the boiler.

The integrated PLC control system monitors and logs all the relevant operational data which is displayed on the touchscreen complete with remote transmission and communication. Feedwater flow and temperatures are continually monitored in order to quantify the amount of energy recovered and calculate the monetary savings.
