Kaeser Australia has released a new oil-free compression rotary screw compressor suited to specialised engineering applications such as pharmaceuticals and chemical manufacture.
The new CSG.1 rotary screw compressors have air flow rates ranging from 4 to 15 cubic metres per minute and pressures up to 11 bar.
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 CSG.1 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 compressors have a residual oil class 0 certificate confirmed by TÜV Rheinland in accordance with ISO 8573-1, minimising the risk of potential product contamination though a Hazard Analysis Critical Control Point (HACCP) analysis.
Its Sigma Control 2 controller enables connection to any master compressed air management system and continually monitors sensors throughout the CSG.1 (including motor bearing temperature, winding temperatures and airend vibration) to ensure it is operating within its optimal conditions at all times.
Kaeser says this means the CSG.1 series compressors can deliver 16 per cent higher flow rates from the equivalent power-rated motor in prior models.
Additional improvements to the compressor heat recovery systems allows the heat generated by compression to be easily incorporated into other aspects of the business, such as space or process heating, thus allowing maximum reduction in the CO² footprint.
The updated CSG.1 series sees service intervals for the compressor as well as gear oil changes extended by 50 per cent. This reduces service costs and means fewer materials are consumed.
