For greater peace of mind in food and beverage, pharmaceutical, electronics, chemical, laboratories, and other applications with the most stringent air purity needs, the 60 hp oil-free compressor in the KAESER CSG series delivers more reliably safe and energy efficient compressed air with no compromises. We designed the CSG to minimize all aspects of life-cycle costs, and it is full of features that extend maintenance intervals and service life while reducing energy costs - and all in a 20% smaller footprint that offers maximum flexibility in planning and installation. With the CSG series, KAESER has delivered oil-free that is trouble-free.

The CSG series features KAESER’s unique two-stage airend block with a biocompatible three layer coating that meets FDA standards. This combination of nanoceramics and high-performance polyetheretherketone (PEEK) is more durable and will not wear off like PTFE or other coatings. Other components in the compressed air pathway are also coated or made from food safe materials, and the compressors are 100% silicone-free. To remove moisture, CSGs are available with integrated refrigeration or desiccant dryer options.

With the 60 hp CSG compressor, KAESER has upgraded its oil-free compressor design to extend service intervals and eliminate maintenance points to reduce costs while increasing reliability and uptime. Our new inlet valve has an extended service life and the pulsation dampeners are maintenance-free. Compressor stages and gear fluid service intervals are 50% longer. Maintenance intervals on the condensate drains are three times longer.

With the SIGMA CONTROL 2 and a suite of sensors, the operation of your CSG is constantly supervised. Vibrations, motor winding temperatures, motor bearing temperature, and automatic lubrication, for example, are all tracked by the SIGMA CONTROL 2. Conditions can be easily monitored remotely within your internal systems or remotely as part of a service plan to avoid problems before they create costly repairs or downtime.

An all new SIGMA PROFILE airend, designed and built by KAESER, in combination with the highest drive motor efficiencies uphold the KAESER reputation for energy efficiency. CSG units boast up to 16% more flow and as much as a 19% improvement in specific performance, with a maximum operating pressure increased to 160 psig. SIGMA FREQUENCY CONTROL (SFC) models leverage the advantages of synchronous reluctance IE5 motors to ensure the highest levels of energy efficiency. On both fixed and variable speed units, a speed-controlled radial fan maintains proper cooling air flow while minimizing power.
