Bitzer tandem compressors and check valves
Hello again my dear Friends.
This time i have a small question about compressor like one in that link: http://pdf.directindustry.com/pdf/bitzer/semi-hermetic-recip-compressors-tandem-kp-110-3/17562-114281.html
and check valves... in my opinion it is like two separete compressors connected in parallel so i have to put in check valves on both discharges.
Am i right?
Thanks for opinions, Marcin
Have a nice day!

Certainly a good idea to add individual discharge check vavs, plus oil balance line as well.

Check valve on each compressor , gas balancing line and of course oil balancing line as mentioned in magoo`s post. If low evaporating temp below minus 15 deg c an oil separator would be requd
