Kaeser DSG-2 RD series compressor with integrated dryer

Kaeser Compressors has launched an updated version of its DSG-2 dry-running rotary screw compressor range. The Kaeser DSG-2 RD series include an integrated i.HOC rotating dryer, able to efficiently achieve pressure dew points as low as -40°C.

With the i.HOC rotating dryer, the heat that is a by-product of air compression is used to regenerate the desiccant. The heat is essentially available for free, as no additional energy is required to power the drying process and the dryer takes advantage of the entire quantity of available heat. As a result, low-pressure dew points can be achieved even in challenging conditions, such as low pressure, high temperature or low load operation.

The integrated Sigma Control 2 compressor controller manages the entire process, controlling the radial blower and drum drive of the i.HOC integrated rotation dryer. Regardless of the operating conditions or the required air delivery volume, the controller automatically adjusts accordingly to ensure consistent production of pressure dew points down to -20°C and, under special conditions, down to as low as -40°C.

The DSG-2 RD series dry-running rotary screw compressors with i.HOC are available air- or water-cooled, with drive powers ranging from 90 to 200 kW, and provide free air deliveries for the complete package at a working pressure of 13.1 to 28.6 m³/min. Variable speed models are also available, with drive motors from 110 to 200 kW and free air deliveries for the complete package at a working pressure of 8.5 to 30 m³/min.
