Differential pressure regulator
The differential pressure regulator is
an important safety element of this
unit. It is fitted at the heat exchanger
of the hydraulic circuit.
The differential pressure regulator
ensures that a volume of water that is
adequate for the compressor opera-
tion is available in the hydraulic cir-
cuit.

This prevents damage to the heat
exchanger, e.g. as a result of a circu-
lation pump failure or through icing up
of the hydraulic circuit.
