Support for Legacy Systems: Forane® 427A

While the industry moves toward lower-GWP refrigerants, Forane® 427A remains a reliable retrofit option for existing R-22 systems. It offers a practical solution for extending the life of older equipment without major system modifications.

However, it's important to note that refrigerants like 427A are subject to future phase-downs under the AIM Act and international climate agreements. As such, they are best used as transitional solutions until full system upgrades can be implemented.

 

The Bottom Line

Whether you're designing new systems or upgrading existing ones, Forane® 448A, Forane® 449A, Forane® 452A, and Forane® 513A offer a range of solutions that balance performance, safety, and environmental responsibility. These refrigerants are engineered to meet the evolving needs of commercial and industrial refrigeration—today and into the future.
