Refrigerants and the A2L Transition
APR Control and the APR‑E Valve support both legacy and A2L refrigerants, allowing owners and operators to improve performance today while maintaining flexibility for the future.
The refrigerants we support
A2L
R-454B
Current 2025 install package. APR Control is sized and selected per application.
A2L
R-32
Current 2025 APR-32 install package. APR Control is sized and selected for R-32 systems, so new A2L equipment modulates instead of short cycling from day one.
Installed base
R-410A
The equipment already on the roof. Rather than replace R-410A systems during the transition, a retrofit keeps them running longer with continuous capacity modulation.
Legacy
R-22
Legacy R-22 systems are supported, so older equipment keeps holding comfort and humidity while you plan the transition on your terms.
