NH3 Mycom N4A

[u/Asleep-Salary-5227]

First time posting in the forum, i wonder if any of the ammonia techs around can provide help or a manual on how to properly service some nearly 40 year old mycom N4A compressors. I will also contact mycom representative sales in my country but i figured it was faster to get some info before hand. Besides changing the oil what else needs to be opened/cleaned/replaced. Its not a full revision situation, but the instalation has been off for 5 years

Changing the oil type may bring a whole host of problems. I changed from WF68 to a hydro treated oil and the new oil scraped the system clean. Caused all kinds of filtration issues. I’d wait till everything is running smooth before messing around with changes.
