Poor Temperature
Stability
The System III is designed to maximize heat removal with minimal facility
cooling water requirements. Under conditions of excessive cooling capacity,
instability may result. The condition may be aggravated by :
High temperature setpoint
Low facility water temperature
Small heat load
High facility water pressure
The situation can be remedied by limiting the available facility cooling water.
Facility water pressure can be reduced with a pressure regulator before the
System III. However, excessive restriction of facility water will reduce the
System III's capacity.
