Gas Detection Solutions for HVAC Applications

Reliable Gas Detection for HVAC Safety & Performance

Heating, ventilation, and air conditioning (HVAC) systems must be safe, efficient, and compliant.

At Dynament, our infrared (NDIR) gas sensors provide accurate detection of refrigerants, hydrocarbons, and carbon dioxide (CO₂), enabling improved safety, reduced energy waste, and enhanced regulatory compliance.

Why Gas Detection Matters in HVAC

In HVAC environments, gas leaks can:

• Impact comfort and indoor air quality

• Reduce system efficiency

• Create fire or health hazards

• Lead to regulatory non-compliance

Our sensors help detect issues early so systems stay safe and efficient.

Key HVAC Applications

Refrigerant Leak Detection

Refrigerants (e.g., R-32, R-454, R-290) may be flammable or harmful if they leak. Early detection:

• Prevents energy loss

• Reduces greenhouse gas emissions

• Supports compliance with F-gas regulations

Recommended Refrigerant Sensors

Refrigerant Infrared Gas Sensors – Platinum Series
Accurate, temperature-compensated detection of standard refrigerants. Ideal for leak monitoring in AC and chiller systems.
Infrared Gas Detector – Axiom Series
Certified to UL60335-2-40 Annex LL, with high-resolution detection, long lifespan, and no calibration required. Designed for demanding refrigerant monitoring in HVAC and chiller applications.

Hydrocarbon Gas Detection for HVAC Applications

Hydrocarbons can accumulate in air handling units, plant rooms, and mechanical spaces. Our NDIR hydrocarbon sensors provide reliable detection of gases such as methane and propane, helping prevent safety risks and improving HVAC system control.

Benefits of hydrocarbon monitoring in HVAC:

• Early detection of methane and propane leaks

• Supports automatic alarms and ventilation control

• Helps protect occupants, equipment, and critical assets

Recommended Hydrocarbon Sensors

Hydrocarbon Infrared Gas Sensors – Platinum Series
High-accuracy methane and propane detection, with linearised outputs and low-power options for integration with building systems.

CO₂ Air Quality Monitoring

High CO₂ levels reduce comfort and cognitive performance. Continuous CO₂ monitoring:

• Improves ventilation control

• Enhances indoor air quality

• Reduces energy use by ventilating only when needed

Recommended CO₂ Monitoring Sensors

Carbon Dioxide Infrared Gas Sensors – Platinum Series
Wide measurement ranges from 500 ppm to 100% CO₂, dual-gas capability, and stable output for accurate air quality control.

Smart HVAC Integration

Our gas sensors support modern HVAC control systems by:

• Feeding real-time data to building management systems

• Enabling demand-controlled ventilation

• Optimising energy recovery ventilators for efficiency
