The EKC 326A controller can be used in systems with transcritical and subcritical cooling control systems where CO2 is used as a refrigerant.. The controller regulates the pressure in the gas cooler (condenser) so that the system achieves the optimal COP. The pressure in the gas cooler is controlled by the ICMTS valve. Regulation must have inputs from both a pressure transmitter PGC (MBS 3000) and a temperature sensor S2GC. The ICMTS valve has been specially developed for the pressure conditions that exist in a transcritical CO2 system. The motor section of the valve is an ICAD actuator and is controlled by a 4-20 mA signal from the controller. Guarantees an optimal operating situation in the subcritical range, so that the best possible COP is achieved. On/off input to start/stop regulation. Regulation stops and the valve opens when the input is closed. The function can be wired so that the valve opens when the compressor has stopped. Facility to force the valve to open at pressures over Pgc Max. lim. Facility to use either dP or dT to control subcooling in a subcritical state. (dT is used as a basic principle). PI regulation. 4-20 mA output signal to control the valve. Facility to connect a pressure transmitter so that the pressure in the receiver can be read off. This function requires an external power supply.
