Our semi-hermetic screw compressors are designed for universal use in large commercial or industrial applications.

BITZER screw compressors excel through numerous benefits:

high cooling capacity and performance coefficient with and without economiser operation
integrated, efficient capacity control: 100 % – 75 % (nominal part load) – 50 % (nominal part load)
from model HSK85 stepwise or infinite slider control: 100 % – 25 % (nominal part load)
from model HSN85 stepwise or infinite slider control: 100 % – 50 % (nominal part load)
patented lubrication system and generously sized bearings offer reliable continuous operation
suitable for all current refrigerants
parallel operation with up to six compressors possible.

The capacity range of the individual compressors covers up to eleven displacement stages. Using parallel circuits you can benefit from further system advantages:

high system reliability and redundancy without over-dimensioning
virtually infinite capacity control
high part load efficiencies by powering compressors up and down
compact compressor system with simple maintenance and service.

Our comprehensive range of accessories – oil separators, oil coolers and monitoring modules – permits complete and cost-efficient system concepts up to large-scale compound systems.

Further information and accessories are given in brochure SP-100 and brochure SP-110 or manual SH-100.
