View Full Version : rust inhibitor in glycol?

02-28-2009, 08:46 AM
I recently replaced the pump on my glycol chiller. The new pump has a cast iron housing. I read the article about glycol in the refrig section. It suggests using a rust inhibitor in the glycol loop when there is cast iron in the loop, but doesn't give any suggestions of what to use. I called a local chemical company and they weren't sure what I should use. Does anyone know what I should be looking for?

nevermind. I checked the refrig page again and the whole page showed up. I guess my browser didn't want me to see the whole page before I posted.
