Anhydrous ammonia, by its very nature, invites contamination by moisture. It is a fact that moisture from the air will travel into an ammonia system through a leak even while the ammonia is coming out. In critical applications, it is of utmost importance that all leaks be promptly corrected. Contamination by oil
