Transitioning to Low-GWP refrigerants

In the EU the F-gas regulation enforces the phase down and ban of High-GWP refrigerants over time in favour of Low GWP refrigerants. At Johnson Controls we make sure we have products available that are compatible with the Low-GWP refrigerants, including natural refrigerants, and can safely be used.
