Plate Subcooler
E l e c t r i c a l l y, a thermostat responding to main
liquid line temperature immediately down
stream of the Plate Subcooler controls a sole-
noid valve on the liquid supply line from the
Liquid manifold. This circuit is supplied with
power through parallel auxiliary contactors on
the compressor motor contactors
A liquid line solenoid valve and a T E V c o n-
trol refrigerant flow to the Plate Heat
Exchanger. An EPR on the return suction line
prevents the subcooler temperature from drop-
ping below desired liquid temperature.
Plate Subcooler Controls
Thermostat setting is 50˚F with minimum
differential, or customer specifications.
The T E V should be set with the highest
possible superheat that will still maintain the
desired liquid temperature.
EPR setting is listed on the store legend.
