Kaeser Compressors (Fredericksburg, VA) announces the new SFC 18. With an advanced SynRM motor-drive combination, this 25 hp unit delivers 31-156 cfm with superior part-load efficiency, longer service life and reduced maintenance costs. Developed in partnership with Siemens and specifically designed to work with Kaeser’s SFC models, the SynRM motor-drive combination achieves top tier IES2 classification. This results in better specific performance, especially in the part-load conditions that call for variable speed compressors. Benefits include:
- A design that does not use aluminum, copper or expensive rare earth metals in the rotors. Instead, they are made of electrical steel and feature a special profile. With this unique rotor design, the motors run cooler - resulting in lower bearing and winding temperatures and increased motor life. And because there are no magnets in the rotor, motor service is safer and easier.
- Enhanced overall sustainability. SFC T models with the integrated refrigerated dryers have been upgraded with R-513A, a non-flammable, non-toxic advanced formulation refrigerant. R-513A has 56% lower global warming potential (GWP) compared to the current US standard (R-134a). This, combined with Kaeser’s advanced heat exchanger design, reduces refrigerant requirements without compromising dryer performance.
