A2L Refrigerant Detection System
ICM-A2L-Sensor
Dual Refrigerant Leak Sensor
A2L refrigerant leak sensor designed to detect leaks of mildly flammable A2L refrigerants, including R454B and R32, helping initiate critical safety measures before refrigerant concentrations reach ignitable levels. Engineered for seamless integration into HVAC and refrigeration equipment, this sensor utilizes advanced speed-of-sound technology to deliver high accuracy and fast response times.
Built for demanding environments, the sensor offers exceptional resilience in high humidity and condensation conditions compared to leading gas sensing technologies. Its robust design minimizes maintenance requirements, giving OEMs and end users greater reliability, long-term performance, and peace of mind.
