Method of Cooling Water flows through Shell and Tube with immersion type evaporator and maintains water at required temperature inside the inbuilt SS tank. Separate process Pump will circuit water to the process and returned to the tank. Process pump, Internal circulation pump, Heat Exchanger etc… are housed in the chiller and controled by PLC.
