Advanced Infrared Technology for Modern Leak Detection
The Dynament Axiom Infrared Gas Detector represents a leap forward in refrigerant leak detection. Built around proven non-dispersive infrared (NDIR) sensing technology, it offers precise, early-stage detection of refrigerant gas leaks—supporting safer and more sustainable HVAC, refrigeration, and industrial systems.
How the Dynament Axiom Detects Refrigerants
At the heart of the Axiom detector is a compact optical system with an infrared emitter, a sensor, and a wavelength-specific filter. When refrigerant gases pass through the optical path, they absorb certain infrared wavelengths. The sensor captures these changes to accurately measure gas concentrations and detect leaks quickly.
Built for Compliance with Emerging Refrigerant Standards
As lower-global-warming-potential (GWP) refrigerants—especially A2L-classified options—gain popularity, compliance with evolving safety standards is essential. The Dynament Axiom is fully compliant with UL 60335‑2‑40 Annex LL, making it a future-ready solution for systems using next-generation refrigerants.
Certified for Safety and Performance
Meeting the latest editions of UL 60335‑2‑40 and CSA 22.2 No. 60335‑2‑40, the Axiom delivers certified performance and safety. It ensures manufacturers, engineers, and system integrators meet strict HVAC and refrigeration compliance standards with confidence.
Environmental and Operational Benefits
By enabling early leak detection, the Axiom significantly reduces refrigerant emissions—helping facilities lower their carbon footprint and avoid costly downtime. Its design supports long-term, low-maintenance operation, delivering excellent lifecycle value.
Broad Compatibility with Refrigerants and Applications
The Axiom A2L model is engineered to detect a wide range of refrigerants used across multiple industries:
-
Flammable gases: R32, R454B, R454C, R290 (propane), R1270 (propylene)
-
Non-flammable gas: R744 (carbon dioxide)
These capabilities make it suitable for HVAC systems, cold chain storage, commercial refrigeration, automotive A/C, heat pumps, and more.
Exceptional Accuracy and Maintenance-Free Design
With a high-precision ±3% accuracy at the alarm threshold, the Axiom ensures reliable leak detection over time. Its NDIR sensor core is engineered for longevity—lasting up to 15 years with no field calibration required.
Performance Highlights and Integration Flexibility
The Dynament Axiom offers a combination of advanced features tailored to OEMs, integrators, and facilities engineers:
-
Rapid response time: Detects leaks in less than 10 seconds
-
Multiple output options: Analog (4–20 mA, 0.2–4 V, open collector) and digital (RS-485 Modbus, RS-232 UART)
-
Condensation protection: Internal heater prevents interference from moisture
-
Robust construction: EMC-hardened, fail-safe operation, immune to sensor poisoning
-
Compact and mountable: Measures roughly 1 × 2 × 3 inches with mounting tabs for seamless installation
-
Plug-and-play functionality: No field calibration needed; firmware includes linearization and temperature compensation
Seamless Integration for OEM and Retrofit Projects
Whether you’re designing a new system or upgrading an existing one, the Axiom’s small footprint and versatile connectivity allow for easy integration into most HVAC or industrial platforms. It’s an ideal choice for regulatory upgrades, OEM designs, or retrofit leak detection enhancements.
The Right Choice for Evolving HVAC Technologies
As global regulations drive the adoption of low-GWP refrigerants such as R32 and R454 blends, the Dynament Axiom helps manufacturers and system operators stay compliant while improving safety and efficiency. Its combination of speed, durability, and certification makes it a reliable tool for leak prevention and sustainability goals.
Summary
The Dynament Axiom Infrared Gas Detector sets a new standard in refrigerant leak detection. With fast response, high accuracy, wide refrigerant compatibility, and a durable, maintenance-free design, Axiom helps reduce emissions, protect systems, and meet the latest safety regulations—all in a compact, OEM-friendly package.
