REMKO EFS SERIES

Central hot water preparation unit

The fresh water stations of REMKO are used for hygienic domestic water preparation in connection with buffer tanks. The units are completely equipped with electronic control, speed-controlled high-efficiency pump, flow switch, and plate heat exchanger. The heat exchanger is designed for a high flow rate of 25 l/min (EFS 25), 35 l/min (EFS 35) and/or 50 l/min (EFS 50).

Through the cascading of EFS 35 or EFS 50 to EFS 35/50 Duo, the flow rate can be increased to 64 l/min and/or 100 l/min. The fresh water stations are delivered ready for wall mounting in the EPP housing.
