View Full Version : using alkylbenzene 200 in HC system

22-09-2010, 06:33 AM
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.

Never mind, I decided to do it the right way and remove the accumulators and flush them as the POE oil in the old compressor was black and had particulates in it (maybe carbon from burned compressor wiring?).
