Sensata Launches First A2L Leak Detection Sensor Certified for Multiple HVAC Refrigerants
Solution is the first with full UL Recognition for the use of R454A, R454B, R454C, and R32 under the 4th edition of UL 60335-2-40
Sensata Resonix RGD Sensor detects the presence of A2L refrigerant gases by monitoring the acoustic resonance of the surrounding air
Unique, patented technology provides HVAC manufacturers with an ideal approach to meet new global warming-related regulations
SWINDON, United Kingdom, October 26th, 2023 – Sensata Technologies (NYSE: ST), today announced the launch of the Sensata Resonix RGD sensor, the first leak detection sensor with UL certification for multiple A2L refrigerant gases used in heating, ventilation, and air conditioning (HVAC) equipment. The new leak detection sensors support HVAC manufacturers’ transition to refrigerants with a lower global warming impact.
Sensata’s Resonix RGD sensors leverage patented gas detection technology to meet the needs of HVAC manufacturers using new hydrofluoroolefin (HFO) refrigerants as part of a global shift away from hydro-fluorocarbon (HFC) refrigerants.
HFC gases have been widely used in air conditioning and refrigeration equipment for decades due to their performance characteristics. However, HFC gases have a high global warming potential (GWP) – often hundreds of times more potent than carbon dioxide (CO2). This issue was the driving factor behind the recent Kigali Amendment to the Montreal Protocol, which targets an 85 percent reduction in HFCs in the United States and other developed countries by 2036, and globally by 2047.
While HFOs have a far lower GWP, they are classified as slightly flammable (A2L categorization), and new leak detection design requirements mandate mitigation features to prevent a potential gas buildup.
