In many HVAC system designs, HFC refrigerants are being replaced by hydrofluorolefins (HFOs), a class of A2L gases which have a far lower global warming impact. However, these systems also need refrigerant leak detection systems, as UL requirements (specifically UL/IEC 60335-2-40) mandate sensors to detect leaks and mitigation features to prevent a potential buildup of gas.

The Sensata ResonixTM RGD sensor provides a best-in-class solution for dealing with this unfriendly sensing environment.
