NDIR Dual Refrigerant Gas Leak Sensor
AM4215R-DM SeriesAM4215R-DM Series
Cubic AM4215R-DM Series is an NDIR dual refrigerant gas sensor, supporting both R32 and R454B refrigerant gas leak detection, specifically designed for the HVACR industry as a complete refrigerant detection system (RDS).
Built on advanced NDIR technology, the AM4215R-DM Series delivers excellent long-term stability and refrigerant gas selectivity. It features fast response to ensure timely leak identification. Flexible alarm threshold settings are available for different refrigerants. To ensure accuracy across a wide operating range, AM4215-DM implement matrix calibration to maintain accuracy throughout the full working temperature range.
Designed for high reliability, AM4215R-DM Series supports continuous operation in harsh environments, including temperatures from -40°C to +95°C, and features IP54 protection along with salt spray corrosion resistance. An integrated dynamic heating control mechanism effectively prevents condensation and frost formation and enables fast recovery after frosting, allowing the sensor to operate reliably in high-humidity, low-temperature, or frequently cycling environments.
The AM4215R-DM series offers dual relays mitigation functions, while being complemented by LED alarm indication and self-diagnosis for intelligent mitigation control. The compact, optimized structural design also supports both integrated wiring-harness and non-harness variants to simplify installation, making it suitable for inside outdoor units, air ducts, or other potential leak points.
With both sensor and RDS certification available based on the standards of UL60335-2-40 and UL60335-2-89, the Cubic AM4215R DM series is a reliable, high-performance solution for refrigerant leak detection, combining accuracy, durability, and installer-friendly design for HVAC&R applications, including air conditioning systems, residential and commercial heat pumps, and industrial cooling and cold chain and so on.
