A2L Refrigerant Leak Detection Sensor Solutions

In today's age of dynamic technological advancements, ensuring the safety and efficiency of HVAC/R systems has become more crucial than ever. Amongst the critical aspects of these systems, one that stands out is A2L refrigerant leak detection.

A2L refrigerants, despite being environmentally friendly and energy-efficient, are mildly flammable, making them a potential risk if not managed effectively. Here is where our MEMS A2L refrigerant leak detectors come into play.

Why is A2L Refrigerant Leak Detection So Crucial?

The importance of A2L refrigerant leak detection cannot be overstated. Early detection of A2L refrigerant leaks prevents the escalation of potential fire hazards, protects against possible health risks, and saves valuable energy by ensuring your HVAC/R systems function at their highest efficiency.

Moreover, identifying and repairing leaks promptly helps in reducing greenhouse gas emissions, thereby playing a significant role in combating climate change and promoting a sustainable future.

The Right Sensor for the Right Job

Posifa’s MEMS refrigerant leak detectors use proven thermal conductivity technology to detect refrigerant leaks. Since refrigerants and air have very different thermal conductivity, a variation in the refrigerant concentration results in significant changes in the thermal conductivity of the gas mixture, which our sensor uses to detect a refrigerant leak. Its precision in detection can achieve a threshold as low as 20 ppm.
