Classifications
UN Number: 3340
Class: 2.2
Uses and Features
- Large commercial refrigerated air conditioning systems.
- A replacement for HCFC-22.
Material Compatibility
Most common materials are suitable for use under normal conditions in a dry system. At high temperatures, use stainless steel or lnconel to resist corrosion breakdown products. Avoid using alloys with more than 2% magnesium (i.e. some aluminium alloys ) especially when moisture is present. May react violently with sodium, potassium, barium and other alkali or alkaline earth metals. Flexible hoses or gaskets should not contain natural rubber as rapid withdrawals of gas/liquid can extract compounding ingredients and it also suffers from excessive swelling.
