50 to 500 Ton Central Chiller

MX Series Central Chillers use a compact rotary screw compressor for greater reliability, energy efficiency and noise reduction. Each independent refrigeration circuit contains a brazed plate evaporator for greater chiller reliability and features a powerful controller to monitor, control and maintain stable and reliable operation of the chiller.

MX Series Chillers now come standard with Dynamic Lift technology to continuously calculate the lowest allowable refrigerant pressure for any combination of operating conditions for maximize chiller energy savings and more stable and smooth control of refrigerant pressure, especially under varying load and condenser inlet temperatures.
