View Full Version : Dunham-bush PCX290-0HR oil question
02-25-2013, 07:50 PM
My company is removing two of these screw machines which are Dunham-bush mod. PCX290-OHR 1979 chillers and I am trying to find out how much oil they hold as my guess is about 80 gallons. I tried to find a O+M maunal but had no luck. We removed the R-22 Freon today and it had 355 lbs in it. Thanks for your response in advance.

I don't know how much they should have, but I would be surprised if they don't more than that. That's just a generalization based on their age. I'm not familar with those machines. Have you removed the oil already, and want to compare the amount with the correct amount?
