Screw Compressor OSKB - OSKB8561-K
OSK = Application for air-conditioning and medium temperature cooling
OSKB compressors are primarily used at the low-temperature stage of booster refrigeration systems. Thanks to their unique design, they’ve gained a great deal of trust among large-scale commercial and industrial users. In conjunction with OSK compressors for the high-temperature stage, a single refrigeration system can, for instance, accommodate low and medium temperature applications – for a simple, compact and cost-efficient solution.
- High system output
- Optimal capacity adjustment and minimal energy requirements under full- and part-load
- Combination of various compressor sizes
- Large bearings
- Coupling and coupling housing for direct drive with IEC motors
