Kaeser Compressors' CSG offers up to 16% more flow and as much as a 19% improvement in specific performance over the previous models, with a maximum operating pressure increased to 160 PSIG, the company reported. The CSG series is available in five fixed speed models from 50 to 125 HP delivering flows from 184 to 563 CFM as well as four frequency controlled (SFC) models with flows from 142 to 584 CFM. SFC models leverage the advantages of synchronous reluctance motors with class IE5 efficiency to provide the highest levels of energy efficiency. On both fixed and variable speed units, a speed-controlled radial fan working in conjunction with the SIGMA CONTROL 2 regulates the fan speed, controlling the cooling air flow for additional energy savings.
The CSG series represents the latest generation of oil-free technology, combining Kaeser's SIGMA PROFILE rotor design with a new nonwearing coating that meets ISO 22000 requirements for peace of mind in food and beverage, pharmaceutical, chemical, laboratories and other applications requiring oil-free air.
Joe D'Orazio, Kaeser's National Sales Manager, said: "At Kaeser we value life-cycle cost, and with the CSG.1 have a solution that increases our customers' maintenance intervals and reduces their utility costs. From the automatic motor bearing lubrication, temperature and vibration monitoring, to the new smaller footprint, our engineers painstakingly crafted the next generation of Kaeser oil-free compressors for the demands of 24/7 manufacturing."
"The patented triple-layer PEEK and nanoceramic coating represents a significant advancement in rotor coating for exceptional durability and long-lasting performance," added Werner Rauer, Product Manager-Compressors. "The food-safe coating represents a significant advancement in technology that will serve our customers well."
Other innovations include a water-jacket cooling design, reliable condensate removal for better corrosion protection, automatic motor bearing regreasing, vibration monitoring and motor bearing temperature sensors. These and other features increase reliability and reduce downtime for maintenance. Its improved service intervals also result in reduced maintenance costs. The new CSG models use 20% less floor space than the previous design, making it suited for businesses with limited space, providing users more flexibility in installation.
