Process Chillers
Overview
The Teqtive water cooled screw chiller is an open-frame package for heavy process loads that run around the clock. Semi-hermetic or open screw compressors paired with a shell-and-tube condenser give high efficiency and long service life in plant-room conditions.
It is offered from 40 TR to 500 TR for chilled water and glycol between +25 °C and −10 °C, and is the usual choice for central chilled-water plants in large factories.
