50HP DWM Copeland Reciprocating Compressor D8DH5-500X-AWM/D

Copeland Compressors in the higher capacity range need some form of capacity control to accommodate varying refrigeration load. 

The capacity control kit supplied by DWM will reduce the refrigeration capacity along with a similar proportional reduction in Power Input. 

This ensures optimum performance even in part load. Capacity control is also required when the condensing pressure falls with a drop in ambient air temperature.

The compressor suction condition, refrigerant volume and mass flow rate will remain unchanged. The capacity will increase due to the increase.
