Kaeser Australia CSG rotary screw compressors

Kaeser Australia’s latest class 0 oil-free compressors are designed for health care, pharmaceuticals, foodstuff, chemicals and other specialised engineering applications that have especially high demands when it comes to compressed air quality.

The CSG.1 rotary screw compressors have air flow rates ranging from 4 to 15 m³/min and pressures up to 11 bar, and customers are offered the choice of air- or water-cooling, and can select an optional integrated refrigeration dryer or an i.HOC (heat of compression) dryer.

The compressors can be specified as a fixed-speed, fixed-flow-rated machine or, for applications with fluctuating compressed air demand, variable-speed-controlled ‘SFC’ versions are available with IE5 Ultra-Premium Efficiency synchronous reluctance motors.

The risk of potential product contamination by oil from the rotary screw compressor is evaluated and minimised by means of an HACCP (Hazard Analysis Critical Control Point) analysis. Process validation is made easier with the residual oil class 0 certificate in accordance with ISO 8573-1.

CSG.1 has also been certified according to ISO 22000:2018, which covers the manufacture of food and beverage equipment. To further formalise the supply chain’s integrity, customers can also option the CSG.1 with Pharmaceutical, Food or Engineering Industry Certification Packages. Additionally, customers can request certification that the machine is free of silicone contamination, as per VW PV 3.10.7.

The updated CSG.1 series is able to deliver 16% higher flow rates from the same power-rated motor as previous. A further aim of the range’s refinement was to improve the compressor heat recovery systems.
