This compressor extends horsepower and flow range
The newly launched SFC 110M variable-frequency-drive compressor (photo) extends the SFC product series to 150 hp, with a 110-kW permanent-magnet motor, and enhances the flow range up to 742 ft3 /min at 100 psig. The SFC 110M features a new Sigma Profile airend, driven by a permanent-magnet motor. This combination boosts energy performance and flow with a smaller physical footprint and less heat, the company says. The new model inherits all the features of the products currently in the series, such as the speed-controlled fan with a brushless direct-current (d.c.) motor for better cooling, and the Sigma Control 2 for superior condition monitoring and external communication capabilities. Other key features of the SFC110M include: improved energy performance, with flow increases up to 20% and specific power below 18 kW/100 ft3/min; improved maintenance access for faster service, including fluid changes and valve maintenance; optional integrated refrigerated dryers; and reduced environmental impact from lower energy usage. — Kaeser Compressors, Coburg, Germany
