Automotive-grade NDIR propane gas detection module for A3 flammable refrigerants
The MAXMAC A3 R290 Refrigerant Leak Detection Sensor - R2 is an automotive-grade NDIR gas sensor module designed to detect leaks of A3 R290 refrigerant (propane). It is suitable for HVAC and refrigeration systems as well as electric vehicle (EV) thermal management, vehicle heat pump A/C systems and battery thermal management applications. Built for demanding automotive environments, R2 supports stable operation under vibration, wide temperature variation and complex electromagnetic conditions.
Suitable for A3 R290 refrigerant leak detection in air conditioning, heat pump, commercial refrigeration, cold-chain equipment, industrial refrigeration plant rooms and HVAC systems. R2 monitors R290 propane concentration in real time and can connect with ventilation systems, alarm devices, equipment controllers or safety protection systems to help detect flammable refrigerant leak risks early and improve site operating safety.
Suitable for heat pump equipment production, refrigeration system assembly, laboratory testing, industrial refrigeration plant rooms and related safety monitoring environments. It continuously monitors A3 R290 refrigerant (propane) concentration and can be linked with ventilation, alarm and equipment control systems to reduce hazards caused by propane gas accumulation and protect personnel, equipment and production environments.
Designed for electric vehicle heat pump A/C systems, battery thermal management systems and vehicle refrigerant circuits. R2 monitors A3 R290 propane refrigerant leakage in real time and outputs detection signals to vehicle controllers, A/C controllers or safety protection systems. Fast leak warning, ventilation control, derating strategies or shutdown protection help improve thermal management safety and reliability in electric passenger and commercial vehicles.
