The Resonix RGD sensor detects leaks of refrigerant gases used in heating, ventilation, and air conditioning (HVAC) equipment.
It has been designed to detect leakages of hydrofluoroolefin (HFO), a new set of refrigerants that are being used as the industry shifts away from hydro-fluorocarbon (HFC) refrigerants, which have high global warming potential. The disadvantage of HFOs is that they are slightly flammable and so leak detection design requirements mandate mitigation features to prevent a potential gas buildup.
The Resonix RGD sensors feature patented technology that measures the acoustic resonance of the surrounding air in real-time. Typically mounted near the evaporator coil, the sensors can trigger mitigation, such as a fan, when gas is detected – venting it before it reaches unsafe levels.
The sensors deliver a fast response time with a life expectancy of more than 15 years and because the sensors do not require field calibration or re-zeroing, they reduce service costs for both installers and end users.
