Retrofit Technical Advice

Whether looking to change from CFCs, HCFCs, or HFCs, Messer can help you choose from our full range of refrigerants available

These include HCFCs, HFCs, HFOs and natural refrigerants, advising which ones best meet your needs.

Messer offers many products that are ‘drop-in’ replacements, which need minimal system changes and often require no oil changes.

The best decision will depend on several factors, including the age, working life, condition, operating costs, current refrigerant used and application.

HCFC Retrofit Information

In many systems, it is possible to remove all of the existing HCFC refrigerants and replace with a ‘retrofit’ HFC product. In many of these cases, the retrofit product is a ‘drop in’ replacement that will only need a small number of system changes to be made, such as adjustment to expansion valves and in some cases, oil changes.

The diagram below is a summary guide to HFC alternatives to existing HCFC systems.
