Available with drive powers ranging from 37 to 90 kW, the two-stage machines of the CSG-2 series provide free air deliveries from 4.8 to 12.7 m³/min for pres-sures between 4 and 10 bar (g). Together with the existing DSG-2 and FSG-2 series, Kaeser‘s dry-runner range now covers free air deliveries from 4.8 to 50 m³/min, or even or 51.8 m³/min with variable speed control.
Ensuring ultra-efficient compressed air production at all times, CSG-2 systems are the ideal choice for applications where dry-compression is required. Users can choose bet-ween air- and water-cooled versions and also have the option of SFC variable speed control for applications with fluctuating air demand.
At the heart of these versatile units lies a quality, two-stage compressor airend. The rotors are equipped with “Ultra Coat”, which is resistant to temperatures up to 300 °C. Because this cost-reducing coating is also highly abrasion-proof, its sealing and protection performance remains virtually unchanged even after years of operation. As a result, compressed air delivery also remains consistent. In other words, dry-running rotary screw compressors from Kaeser consume no more energy after years of use than when first commissioned in order to deliver their rated free air delivery.
