High efficiency and quiet operation at an affordable price The 140 to 200-ton Model AGS Screw Chiller is ideal for projects requiring efficiency that meets ASHRAE Std. The quiet operation of this unit is a result of our advanced single screw compressor design. These chillers use R-134a refrigerant which has no ozone depletion potential and no phase-out date. Available options provide the flexibility to meet a variety of project configurations. Factory installed pump package. Remote evaporator to keep chilled water piping inside the building.
MicroTech II® controls with the Open Choices ® feature for easy integration using BACnet®, LonTalk® or Modbus® standard open protocols.
