Heat exchangers dedicated for ground source heat pumps.


With a proven design and performance, RAD shell and coil heat exchangers are perfect for refrigerant applications, especially in groundsource heat pumps powered by water from well, lake or river.

Direct refrigerant inlet into each of the heat exchanger tubes ensures uniform medium distribution. RAD has a high heat
transfer coefficient and is designed for modern A2L refrigerants such as R32, R452B, R454B. With compact dimensions and vertical installation, the exchanger’s footprint is greatly reduced. RAD has been designed to work with pressures up to 45 bar.
