Kaeser CSG-2 series oil-free rotary screw compressors

Kaeser Compressors has launched two additional versions of its CSG-2 series dry compression rotary screw compressors: the CSG-2 T with integrated refrigeration dryer and the CSG-2 RD with integrated i.HOC rotation dryer. The series offers a complete compressed air system package wherever an efficient and dependable source of high-quality and clean compressed air is required.

For applications that require pressure dewpoints to +3°C, the CSG-2 T series screw compressors are available with an integrated refrigeration dryer. All refrigeration dryer components in the series are accessible via the service door on the front of the unit for ease of maintenance and service work.

Where pressure dewpoints below +3°C are required, the CSG-2 RD series screw compressors with an integrated i.HOC rotation dryer can achieve pressure dewpoints as low as -30°C. The hot compressed air from the second compression stage is used to regenerate the desiccant. This heat is essentially available for free, as no additional energy is required to power the drying process.

The rotary dryer’s intelligent control ensures dewpoint stability even with fluctuating flow rates and at compressor partial load. When commissioned, the target pressure dewpoint is reached after just one rotation of the drum. As a result, the end user obtains an air dryer with maximum efficiency and lower energy costs.
