New UL certification for CAREL products using A2L refrigerants

CAREL has obtained UL LZGH2/8 certification for a selection of “A2L ready” products, confirming their suitability for use in systems with mildly flammable refrigerants and full compliance with the safety and sustainability standards required by the global HVAC/R market. The certification covers the pCO (pCO5+), c.pCO (c.pCO and c.pCO mini), c.pCOe I/O expansion, k.air, pRack, and io.module ranges.

The choice of low-GWP refrigerants, internationally promoted by regulations such as the F-gas and AIM Act, is pushing industry players to find increasingly sustainable solutions. However, many of these alternatives, such as A2L refrigerants, are flammable and require components certified to specific standards, such as IEC 60335-2-40.

The UL LZGH2/8 certification simplifies the integration of CAREL components into systems, reducing the time and costs associated with leakage tests and enhancing overall equipment safety. CAREL has long adopted a proactive strategy to identify and develop components that are not sources of ignition, thereby contributing to the acceleration of the ecological transition in the sector. The UL certification, valid for both the US and Canadian markets, ensures a higher level of reliability and faster approval processes.
