I have a ice maker bank type chiller for industrial machine cooling (cools 100 gallon tank of water that circulates through machines and it was using 134 and POE oil, I have to replace the compressor that is filled with Alkylbenzene oil and I am converting to an HC blend. The system has several small 'holding' tanks and I was worried POE oil could be lurking there that might cause problems. There shouldn't be very much left but could the POE oil mix with the alkylbenzene oil okay?
I am replacing the sight glass and drier.
Thanks!
