Hi we are seeing R290 Bev. Fridges come to market.
But the ambient temp. here is normally 45 degrees Celsius how does R290 cope with this and what is the terminal protection temp. on these compressors?

R290 (and mixtures that are mostly R290) doesn't heat as much on compression. Therefore, R290 can work with a larger compression ratio and/or higher condensing temperature and still have the discharge temperature well within specification.

Thank you. Can you maybe point me in the right direction to obtain all the temp. specs on R290.
