Screw compressor units SABflex

Small screw compressor units with swept volumes of 160–950 m3/h

SABROE SABflex screw compressors are specially designed for installations where the requirements for refrigeration capacity vary over time. These smaller-size units are optimised to ensure exceptional part load performance as well as the best possible energy efficiency.

Everything about these units is configured for use with variable-speed drive (VSD), doing away with the traditional capacity slider and ensuring skip-free performance across the entire 1,000–6,000 rpm capacity range.

The VSD drive can be mounted on the unit, or separately in an appropriate switchboard room.

Range

SABflex units are available to provide swept volumes of 160–950 m3/h at 6000 rpm using a high-speed motor, or 160–570 m3/h at 3600 rpm using a standard motor.
