What is the replacement for R-410A?
A lower GWP replacement for R-410A is Forane® R-32. Forane® 32 is a stand-alone third generation refrigerant for new residential and light commercial air conditioning systems, heat pumps and other HVAC applications.
Slightly flammable (A2L according to the ASHRAE 34), Forane® R-32 can be used in new equipment designed specifically for mildly flammable refrigerants as a suitable replacement for R-410A equipment. Its low density allows for option to use a smaller refrigerant charge. Consequently, there is a double advantage of Forane® R-32 versus other high-density solutions.
Benefits of R-32 over R-410A
Unlike blended refrigerants, R-32 is a zero ozone depleting single component refrigerant: Difluoromethane. Using R-32 refrigerant is not only useful for direct emission reduction but also indirect impact on global warming. When using Forane® 32, equipment manufacturers reported an increase in system efficiency and seasonal energy efficiency ratio when compared to R-410A.
- Forane® 32 allows the use of the same existing component technologies developed for R-410A installations.
- Forane® 32 allows for the use of smaller compressor and heat exchanger versus R-22, which lowers manufacturing equipment cost.
- Forane® 32 equipment size is reduced versus R-22 equipment, which allows for easier handling and integration in the buildings.
- The GWP of Forane® 32 is 677 according to AR5, and the effective FORANE® 32 GWP is around 474.
- As a single component refrigerant Forane(R) 32 has zero glide and is easier to recycle at end of life.
Applications For Forane® R-32
Forane® 32 can be used for all types of air conditioning technologies, including heat pumps and water heaters. You can also find refrigeration equipment using Forane® 32 refrigerant in the market.

R32 For You– Did you know R-32 is a single molecule? Learn how this can make your life easier.
You may have already heard about the environmental benefits of R-32. But do you know specific ways that R-32 can ease some of the burden on an installer, contractor, or property owner? Unlike many modern blended refrigerants, R-32 is single molecule making it easier to handle.
1. R-32 can be topped off. – Because it’s a single molecule, R-32 can be topped off without a change in composition.
2. R-32 can be reclaimed. – That single molecule comes in handy! It makes R-32 easy to reclaim.
3. R-32 has zero glide. – Unlike a zeotropic blend, R-32 has one boiling point making it easier to work with.

How Does Forane® R-32’s Thermal Management Affect You?
R-32’s excellent thermodynamic properties set off a chain of events that ultimately benefit everyone from the Manufacturer to the Installer
- Less Refrigerant - When working with R-32, you need less of it because of its excellent thermal management properties. This means that product designers can use smaller refrigerant loads when designing the unit.
- Smaller Units – When manufacturers have smaller refrigerant loads to specify in a unit, designers can create smaller, lighter weight units.
- Easier Installation – Installing a smaller, lighter weight unit is easier than bulkier units of the past.
