CAREL receives UL certification for A2L-ready control components

CAREL has obtained UL LZGH2/8 certification for several product lines designed for use with mildly flammable refrigerants. The certified ranges include pCO (pCO5+), c.pCO (c.pCO and c.pCO mini), c.pCOe I/O expansion, k.air, pRack, and io.module.

The certification confirms compliance with safety standards for A2L refrigerants and supports the industry's shift toward lower-GWP alternatives, as encouraged by regulations such as the F-gas Regulation and the AIM Act. A2L refrigerants, while offering lower environmental impact, require components that meet specific safety criteria, including those outlined in IEC 60335-2-40.

UL LZGH2/8 certification facilitates the use of CAREL components in HVAC/R systems by reducing leakage test requirements and accelerating system approvals. The certification is valid for both the US and Canadian markets.

According to CAREL, this initiative aligns with the company’s long-term strategy to develop non-ignition-source components and support the sector’s ecological transition.
