Carlo Gavazzi: New DPA 3-Phase Voltage Monitoring Relays for HVAC Systems Using Low-GWP Refrigerants
The HVAC industry is undergoing a profound transformation. Manufacturers are phasing out high-GWP HFCs in favor of next-generation refrigerants such as R-32, R-1234yf and R-290. While these alternatives support climate goals, they also present a higher ignition risk—requiring strict compliance with IEC/EN 60335-2-40 and UL 60335-2-40 safety standards. Carlo Gavazzi’s new DPA relays provide a reliable and certified response to this challenge. Designed to operate completely spark-free, they meet the ignition-free requirements for A2L and A3 refrigerants.
