Screw Compressor OSN - OSN5361-K (R407F)
Low temperature range, Economiser operation
OSK = Application for air-conditioning and medium temperature cooling
BITZER’s open screw compressors for use with NH₃ have been proving their worth on the market for many years. We offer these robust and efficient solutions for use on their own and in parallel operation with several compressors and a shared oil separator. The combination of open compressor and external standard motors makes the series exceptionally flexible and allows operation at different supply voltages. BITZER has the appropriate couplings and coupling housing as accessories in its portfolio, making it safe and easy to combine compressors with external standard motors. A significant improvement: the refrigerant circuit and electrical drive are separate, making maintenance and repair much simpler. To complement the open OS.A screw compressors, we’ve developed a complete portfolio of tried-and-tested accessories for use in large-scale commercial and industrial NH₃ refrigeration and air conditioning systems.
The OS.A95103 compressor marks the beginning of the new OS.95 series. The strengths of this new development include large volume flows up to 1,015 m³/h at 2,900 revolutions per minute, integrated control electronics, an optimised slider concept for seamlessly adjustable capacity control and Vi adjustment for maximum efficiency at every operating point.
- High system output
- Optimal capacity adjustment and minimal energy requirements under full- and part-load
- Combination of various compressor sizes
