I am installing a Rack of 3-35hp refridgeration screw compressors. On this rack there is oil cooling or jet cool. My problem is this cooler has a 1 3/8 in copper going to the condenser along with that is the 2
1/8 in tubing from the high side of the compressor also going to the condenser since the 2 1/8 in pipe is larger than the 1 3/8 in I cannot cool the 1 3/8 in line because of pressure on the 2 1/8 in line. Any help or suggestions for a valve to allow the gas from the 1 3/8 in line to enter the condenser, any help would be greatly appreciated. Feel free to respond to this posting or my email.
