Global Refrigerant Gas Leakage Monitoring Sensor Market Growth 2026-2032
Description
The global Refrigerant Gas Leakage Monitoring Sensor market size is predicted to grow from US$ 129 million in 2025 to US$ 234 million in 2032; it is expected to grow at a CAGR of 8.9% from 2026 to 2032.
In 2025, global Refrigerant Gas Leakage Monitoring Sensor production reached approximately 2.63 million units, with an average global market price of around US$ 50 per unit.
A refrigerant gas leakage monitoring sensor is a gas-sensing device/module used in HVAC&R equipment to continuously detect leaking refrigerants—especially flammable/low-flammability A2L/A3 refrigerants such as R32, R454-family, and R290—and trigger alarms or safety actions (ventilation, load shutdown, warnings) once thresholds are reached. With low-GWP refrigerant adoption accelerating, safety standards such as UL 60335-2-40 emphasize robustness, reliability, drift/deviation handling, and installation/testing requirements, driving a shift from bare sensing elements toward system-level refrigerant detection modules (RDS) with compensation, self-check, and relay/communication interfaces.
Upstream includes sensing elements and critical materials/devices (NDIR IR source/detector and optical cell; thermal-conductivity elements; MOX sensing materials), industrial MCUs/PMICs, relays/drivers, connectors/harnesses, sealed housings for IP protection, and calibration/test tooling. Midstream suppliers integrate compensation (T/H), drift handling/self-test, alarm logic, interfaces (relay, UART/I²C/RS485, etc.), and factory calibration for target refrigerants—often shipping complete modules/systems (RDS). Downstream HVAC&R OEMs and integrators connect sensors with control boards, blowers, valves, and safety logic across air conditioners, heat pumps, refrigeration cabinets/rooms, commercial refrigeration, and cold-chain equipment. Representative midstream examples: Sensirion (thermal-conductivity RDS), Amphenol SGX (NDIR for R32/R290), Figaro (A2L modules).
The annual production capacity of a single-line Refrigerant Gas Leakage Monitoring Sensor is approximately 30k units, with a gross profit margin of approximately 15%-25%.
The market is being reshaped by low-GWP refrigerant transitions, where safety compliance becomes a hard requirement rather than a feature—pushing products from bare sensing elements toward system-level modules with compensation, self-check, drift management, and safety outputs aligned with lifecycle reliability expectations. Selective and environmentally robust approaches (e.g., NDIR and engineered thermal-conductivity systems) tend to gain traction, while modular, reusable interfaces (relay + digital communication) help OEMs reuse platforms and shorten validation cycles. Key drivers include standards/regulations, broader A2L adoption in AC/heat pumps and refrigeration, and OEM preference for diagnosable, serviceable, replaceable modules; headwinds include calibration complexity across refrigerants and applications, harsh field conditions (condensation/oil mist/dust) that can impact false alarms and lifetime, and cost pressure plus supply consistency constraints during scale-up. Overall, suppliers that combine compliance-driven system design, robust calibration/drift control, and integration/validation support are best positioned in the ongoing refrigerant upgrade cycle.
