Principle of Operation:
An intermediate heat exchanger (DP) should be installed to prevent ground water
damaging or contaminating the unit’s internal heat exchanger. A plate heat exchanger
that is able to be cleaned is recommended for this situation that can be disassembled
for cleaning and repair or any damage plates can be replaced. Anti-freezing
measurement must be adopted to protect the ground water circuit.
