Refrigerant Gas Sensors

The Axiom Infrared Gas Detector, developed by Process Sensing Technologies (PST), is an advanced leak detection device using non-dispersive infrared (NDIR) technology to accurately measure refrigerant gases and provide early warning indication of refrigerant leaks.

The detector uses an infrared source, a detector, and an optical filter. When exposed to refrigerant gases, the detector measures the absorbed infrared radiation to quantify the leak accurately.

The Axiom detector is certified to UL60335-2-40, supporting regulations aimed at reducing global warming potential by accurately detecting potential leaks from lower GWP refrigerants that are categorized as lightly combusitble (A2L). The UL 60335-2-40 safety standard includes specific requirements for control logic, testing, and certification of HVAC products using A2L refrigerants, ensuring safety measures are triggered if refrigerant leaks occur.

Yes, the Axiom is certified to UL 60335-2-40 Edition 4 and CSA 22.2 No. 60335-2-40 Edition 4, ensuring the highest safety and performance.

By enabling early detection and mitigation of refrigerant leaks, the Axiom detector helps reduce greenhouse gas emissions and promotes environmental sustainability.

The detector is suitable for HVAC, automotive, and industrial refrigeration applications, providing continuous monitoring and early leak detection in various systems.

The Axiom detector has a 15-year lifespan with no required field calibrations, offering cost-effective and hassle-free operation.

The Axiom detector offers high sensitivity and specificity, ensuring early leak detection, which minimizes environmental harm and enhances safety.

The sensor detects refrigerant gases such as R32, R454B, R454C, R290 (Propane), R1270 (Propylene), and R744 (Carbon Dioxide).

The accuracy is ±3% at the alarm point, ensuring reliable gas detection.
