CSG series rotary screw compressors: Purity and efficiency at the forefront

Pharmaceuticals, foodstuff, healthcare, chemicals – these industrial sectors place especially high demands when it comes to compressed air quality. For those who wish to achieve these requirements cost-effectively, CSG rotary screw compressors from Kaeser represent the perfect choice. These new models are particularly efficient and require very little installation space.
The CSG series provides highly efficient compressed air generation, yet requires 19 percent less floor space than its predecessor range. Models are available with air- or water-cooling, with integrated refrigeration dryer or i.HOC (Heat of Compression dryer), and for flow rates ranging from 4 to 15 m³/min. For applications with fluctuating compressed air demand, speed-controlled “SFC” versions are available.
The CSG series is equipped with high-quality, durable airends featuring the energy-efficient Sigma Profile for which Kaeser is world-renowned. The rotors now feature an innovative new wear-free PEEK coating, which is also particularly temperature-resistant. Biocompatible, FDA-certified and in compliance with European requirements for food contact materials, this coating is perfectly adapted for the pharmaceuticals and foodstuff industries.
When it comes to energy efficiency, the CSG series is the star of its class. Kaeser was uncompromising in its pursuit of efficiency when developing the drive, cooling and compression systems for these models. Therefore, the range is equipped with IE5 Ultra Premium Efficiency synchronous reluctance motors and water jacket cooling on both compression stages – on both air- and water-cooled systems. The fibre-free pulse dampers fitted to the CSG operate on a broad spectrum and at very little pressure loss.
