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.
