A3 Leak Detectors for Hydrocarbon Refrigerants
A3 leak detectors are designed for detecting leaks of hydrocarbon refrigerants such as R290 (propane) and R600a (isobutane), which are increasingly used in modern refrigeration and HVAC systems due to their low environmental impact.
Because A3 refrigerants require careful handling and monitoring, using dedicated detection tools is essential for accurate leak identification and proper system maintenance. A3 leak detectors are built to provide high sensitivity and fast response, helping technicians locate leaks efficiently during installation, servicing, and inspection.
For systems using mildly flammable refrigerants such as R32 and R454B, technicians may also consider A2L leak detectors designed for those applications. In comparison, technologies such as infrared leak detector and heated diode leak detector are commonly used for general refrigerant leak detection in HVAC systems.
