Rotary Screw Chillers

Once dominated by centrifugal machines, chiller sales in the 100-350 ton capacity range today are more often than not rotary screw machines, or screw chillers as they are commonly known. Screw compressors generally use one or two screw shaped rotors to squeeze refrigerant vapor into an ever decreasing volume as it traverses the rotors.

Highly efficient, and with reliability often rivaling that of centrifugal machines, screw chillers are a cost effective alternative in today's market.

Carrier manufactures two different screw chillers, to address two different market needs.
