CHP48-12, Environmental Control System

The CHP48-12 represents the apex of Environmental Control Units' technology. It is a water system Chiller-Heater Plant, with a 48kBTU Cooling capacity and 12kW Heating capacity designed to be used for chamber internal and external chamber environmental control systems. The CHP48-12 comprises of a cold water circuit and a hot water circuit. For chamber environmental control systems using external Regens the CHP48-12 can supply regen units with the required cold water and hot water. Control of hot or cold water flow rates are controlled by the Regen Unit temperature control system. For chamber environmental control systems using internal conditioning units, ICUs  in chambers, the CHP48-12 can be used in conjunction with the ECS Control Valve Assembly to provide control of the hot and cold water flow rates to the ICUs. This controls the temperature and humidity in the chamber.
