Horizon’s Adaptive Cycle Management
The Equilibrium chart below illustrates the Generator
Temperature Limit, the Interstage Pressure Limit and the
Low Refrigerant Temperature Limit areas with respect to
the normal cycle operation. These three limits along with
PID Concentration and Solution Controls provide complete
cycle management.
The white area in the middle of the chart illustrates the safe
cycle operating area. Solution Concentration Control
provides a margin of safety from the cycle to the Lithium
Bromide Crystallization Line.
