Liquid Distributor
Type RD
The RD refrigerant distributors distribute
liquid refrigerants from the thermostatic
expansion valve to individual sections of the
evaporator.
Note!
The thermostatic expansion valve must have
external pressure equalization.
Features y A wide range of RD refrigerant distributors is
available, covering the majority of customer
demands.
y RD design ensures a uniform distribution of
refrigerant to each evaporator section.
y Suitable for refrigerants R22, R134a,
R404A, R407C, R507, R410A.
Concerning other refrigerants
please contact Danfoss.
y Maximum working pressure:
MWP/PS 48 bar/700 psig.
