Using arefrigerant for purging contamintants from a system is no longer acceptable. To remove contaminants from a system and remain environmentally safe, use dry nitrogen. To assure the system is clean of contaminants before charging with reffrigerants, purge the system with low pressure dry nitrogen when brazing. Testing a system for leaks with nitrogen will save time and money. 500PSI Nitrogen regulator can deliver up to 500psig to pressurize a system for leak testing at operation pressure. Always use manufacturer's recommended specifications for Maximum test presure before testing.
