Below is a list of Screw Chiller manufacturers from Wappingers Falls, New York. A screw chiller is a liquid chiller that uses two rotating helical screws to provide the needed pressure to drive the vapor-compression refrigeration process. Screw chillers are more compact, quieter and contain fewer parts than their alternatives: reciprocating, centrifugal and absorption chillers. Screw chillers rarely break down, have long life spans and require little maintenance.
