If your central chilling station is equipped with the optional 
integral pump tank, make the process cooling water supply 
connection at the P1 manifold at the left side of the pump tank at 
the exposed connection. Bring the process cooling water return 
connection to the 

 well of the tank on the right side at the 

flanged connection. 
 
Warm coolant (water and ethylene glycol mixture) returns from the 
process to the tank, then gets pumped through the evaporator 
where it is cooled. The coolant flows to the process and returns to 
repeat the cycle. 

 

 

•

  SSC Series chilling station air- and water-cooled unit 

refrigeration cycles differ only in the way the compressed gas 
is condensed to a liquid. 

•

  Liquid refrigerant from the condenser passes through a shut-off 

valve into a filter/dryer. 

•

  The refrigerant then passes through the sight glass and solenoid 

valves into the thermal expansion valve which regulates flow; 
the valve lowers pressure and boiling point. Heat from the fluid 
causes the refrigerant to boil off into a vapor. 

•

  The refrigerant vapor flows through the suction line back into 

the compressor. 

•

  The refrigerant gives up heat as it re-condenses to a liquid in 

the condenser. 

 
 

The freezestat shuts down the compressor if the chilled water 
temperature approaches the freezing point. The chilled water pump 
on the system will continue to run. It is factory-set at 40°F (4ºC) or 
10°F (6ºC) below the rated capacity operating temperature of 50°F 
(10ºC).
