Danfoss extends operating envelope for DSH scroll compressors

30th November 2021

DENMARK: Danfoss has qualified a larger application envelope for its DSH medium scroll compressors using lower GWP refrigerants R452B and R454B.

As the newly optimised compressors are 100% back-compatible, ordering codes will remain the same.

The maximum condensing temperature has been extended from 65℃ to 68℃. So, high side working range is now 41.7bar(g) and maximum high pressure safety switch setting is adjusted accordingly from 40.6 to 43.1 bar(g).

Due to increased compressor discharge gas temperature, a new acoustic hood has been developed for the R452B/R454B application.

The new enlarged envelope now available with the DSH multi refrigerant Medium range
