Oil-Free Compressors Offer Low Life-Cycle Cost

Description

A line of oil-free rotary screw compressors are now available from Kaeser. The CSG-2, DSG-2, and FSG-2 models cover flows from 192 to 1774 cfm, pressures from 45 to 145 psig, and are available in 50 to 450 HP. Available air-cooled or water-cooled, these two-stage, oil-free air compressors have been designed with energy efficiency, easy maintenance, and low noise levels in mind. Models are up to 9% more efficient than the competition.

 

The core of these versatile models' top performance is their premium, two-stage compressor airend. The rotors' special coating can handle temperatures up to 575°F. This highly abrasion-proof coating will not wear, providing reliable sealing and protection. This means compressed air delivery and energy consumption remain consistent, even after years of operation. Stainless steel rotors in the second compression stage help guarantee compressed air quality and significantly increase service life.

 

Units come standard with Sigma Control 2, which offers unsurpassed compressor control and monitoring with enhanced communications capabilities for seamless integration into plant control/monitoring systems and the Industrial Internet of Things (IIoT).

 

Additional features include IE3 premium efficiency motors with PT 100 sensors to measure and monitor winding temperatures for maximized motor switching frequency and minimized idling. The hydraulic inlet valve eliminates replacing pneumatic diaphragms, resulting in reduced service costs and downtime. Fiber-free pulsation dampeners keep pressure losses to an absolute minimum, maintain consistent air-quality, and prevent compressed air contamination. Built-in heat recovery options give sustainable energy savings and contribute to lowering a plant's carbon footprint.
