Danfoss expands portfolio of oil-free compressors with new TGS490

R515B has an AR5 GWP of 299 and an ASHRAE A1 safety classification for lower toxicity and no flame propagation. As an extension of the existing Danfoss Turbocor® TG series of compressors, it also is qualified to use HFO-1234ze, a refrigerant with a GWP less than one.
