Revolutionizing HVAC Safety: Introducing the Dynament Axiom Refrigerant Infrared Gas Sensor

Hvac safety application

As HVAC systems evolve to meet tighter environmental standards and adopt low-GWP, mildly flammable refrigerants, one challenge looms large: detecting leaks before they become dangerous or costly. That's where the Dynament Axiom Series steps in, offering a next-generation solution that redefines how HVAC professionals monitor refrigerants.

A New Era of Refrigerant Monitoring

Refrigerants are essential to HVAC systems but come with significant safety and environmental considerations. Even minor leaks can lead to:

  • Increased energy use and reduced system efficiency
  • Costly regulatory violations and fines
  • Safety risks from flammable gas accumulation
  • Environmental damage from high GWP refrigerants

  • As systems increasingly adopt low -GWP refrigerants, many of which are mildly flammable, the demand for reliable, real-time leak detection has soared. The Dynament Axiom Infrared Gas Sensor is designed to meet that challenge head-on.


    The Dynament Axiom: Technology Built for Trust

    The heart of the Axiom sensor is non-dispersive infrared (NDIR) technology, a highly stable, selective detection method immune to sensor poisoning, humidity interference, and cross-gas sensitivity.

    Key Features:

  • Fast Response: Leak detection in under 15 seconds for critical early warnings
  • Broad Refrigerant Compatibility: variants for detection of R32, R290, R454B, R744 (CO₂), and other A1/A2/A2L/A3 refrigerants
  • Fail-Safe Operation: Integrated diagnostics and safety output to prevent system errors
  • Zero Field Calibration: Long-term stability with no re-calibration required, ideal for remote or inaccessible installations
  • Onboard Heater: Prevents internal condensation to maintain sensor integrity
  • Compact OEM-Friendly Design: Ideal for embedded applications in residential, commercial, or industrial HVAC systems
  • Robust EMC Protection: Delivers accurate results even in electrically noisy environments

  • With a 15-year design life, the Dynament Axiom sensor offers one of the longest-lasting refrigerant detection solutions on the market.


    Certified for Safety and Compliance

    Regulatory compliance is non-negotiable in HVAC systems using flammable or environmentally sensitive refrigerants. The Dynament Axiom sensor is:

  • UL60335-2-40 Annex LL – Certified for flammable refrigerant applications
  • RoHS & REACH – Environmentally safe, free of restricted substances

  • This makes the sensor ideal for manufacturers and OEMs aiming to meet current and future international regulations.


    Designed for Real-World HVAC Applications

    Whether it's a compact split system or a complex industrial chiller, the Dynament Axiom sensor fits seamlessly into a wide range of applications:

    Use Cases Include: 

  • Residential & Commercial Air Conditioning Units
  • Heat Pump Systems (especially those using R32 or R290)
  • Refrigeration Units in Supermarkets and Food Storage Facilities
  • Industrial Cooling and HVAC Systems
  • OEM Manufacturing for Smart HVAC Equipment

  • With analog and digital output options, integration into existing control systems is straightforward and scalable.


    Integration Made Simple

    The Dynament Axiom is designed with installers and manufacturers in mind. It supports:  

  • Analog Outputs: 4–20mA, 0.2–4.0V, and Open Collector
  • Digital Communication: USB 2.0, RS485 Modbus and RS232 UART
  • USB-C Connector: IP68-rated, allowing for easy commissioning and maintenance
  • Whether you embed it into a smart control board or connect it to a cloud-based monitoring system, the Axiom is built to adapt.

    Environmental and Economic Impact

    Beyond safety, the Axiom supports sustainability and cost reduction:

  • Reduce Refrigerant Emissions
  • Cut Down on Maintenance Visits and Downtime
  • Improve Energy Efficiency
  • Lower Operating Costs

  • For companies working toward sustainability and net-zero goals, sensors like the Axiom are no longer optional but essential.


    Conclusion: A Smarter Way to Detect and Protect

    The Dynament Axiom Refrigerant Infrared Gas Detector is more than just a leak detector; it's a strategic investment in safety, compliance, and long-term system performance. Its fast, accurate, and fail-safe monitoring makes it ideal for the HVAC industry as it evolves toward a brighter, greener future.
