Description

 

 

The cooling unit XRCA-5001-OA is designed to provide a continues flow of cooling 

 

 

fluid at a constant temperature.  

 

Oil circulates between the cooling unit and the heat source.  

 

The oil is chilled by an air-cooled refrigeration system (refrigerant R 134A).The  

 

cooling unit has a main switch to start the refrigeration system. The oil level in the  

 

reservoir is supervised by a level switch. If the level drops below minimum, the  

 

refrigeration cycle stops and the pilot lamp "Oil level low" is activated and the safety  

 

circuit is activated. 

 

The maximum cooling capacity of the cooling unit depends on the ambient and the  

 

fluid temperature. The cooling capacity is 5000W related to 40 °C ambient  

 

temperature and +30 °C ± 2°C fluid temperature  

 

Cooling hoses are connected to the cooling unit via screw connection (M26x1,5). Oil  

 

inlet and outlet are marked with symbols:  

 

Inlet:

O

Outlet:

O

 

 

 

The oil outlet temperature is monitored by an electronic temperature controller.  

 

 

This controller is provided with additional contacts and for temperature maximum  

 

signal. 

 

The signals "temperature maximum" and "oil level low" are combined in a potential  

 

free safety circuit. The oil pressure of the pump is limited by an adjustable bypass  

 

valve. 

 
 

Note: Flow switch, thermal switch and bypass valve are factory adjusted  

 

 

according to specification. 

 

Use only Shell Daial S4 ZX-I to refill the cooling circuit!
