Screw Chillers

The screw chiller is named after the use of a screw compressor. Its cooling power is higher than that of the scroll chiller, and it is mainly used in chemical plants, ink printing plants, automobile manufacturers or central air conditioning systems or other large industrial refrigeration.

In addition to the listed product models, our company can customize non-standard units according to customer requirements.
