Telaire | Refrigerant Gases

Telaire’s T3400 Series Refrigerant Leak Detection Sensors can identify refrigerant gas leaks by assessing the thermal conductivity of a specific gas mixture. In the event of a refrigerant discharge, the variation in refrigerant concentration in the air results in changes in the thermal conductivity of the gas mixture which can measured by the micro TCD sensing element. As compared to competing detection technologies, thermal- conductivity-based detection offers the benefits of superior long-term reliability and resilience in harsh operating environments.

The Telaire T6860 Sensor is a non-dispersive infrared (NDIR) sensor designed for automotive HVAC applications. It detects the presence of potentially hazardous R290 gas in the cabin or under hood, which may result from a refrigerant leak caused by a system failure  or a vehicle accident.
