air cooled screw chiller( screw chiller, water cooled screw chiller, package chiller) adopts branded BITZER compressor with high

air cooled screw chiller( screw chiller, water cooled screw chiller, package chiller)

Screw chillers are used in the mid-range of unit sizes, from around 25 Ton up to 800 Ton. They are compact and have less moving parts, hence lower maintenance costs and longer lifespans. Screw compressor liquid chillers include a slide vane that adjusts the length of the compression path. Inverter-driven, variable-speed electric motors and turbine and engine drives can also modulate screw compressor speed to control capacity. Most screw compressors chillers modulate from 100 % to approximately 10 % load. Hot-gas bypass can be used to reduce capacity to nearly 0 %.
