With Thomas W. Springer’s ever increasing air demand, they upgraded their main compressor to a 30HP Kaeser SFC22T. Their previous Kaeser SFC18T will now be their back up compressor. TWS has been relying on Kaeser air compressors for over 20 years because of their outstanding efficiency and reliability. The SFC’s variable speed frequency drives and integral refrigerated air dryers are critical features that keep TWS’s operation running 24 hours per day, 7 days per week.
