Gas Detection Solutions for HVAC Applications
Reliable Infrared Detection of Refrigerants, Hydrocarbons, and Carbon Dioxide
Heating, Ventilation, and Air Conditioning (HVAC) systems are essential for comfort, safety, and energy efficiency in residential, commercial, and industrial environments. With growing demands for smarter, more sustainable buildings, the role of accurate gas sensing has never been more critical.
At Dynament, we offer advanced non-dispersive infrared (NDIR) sensor solutions tailored for HVAC applications. These sensors provide reliable detection of refrigerants, hydrocarbons, and carbon dioxide (CO₂) to support compliance, safety, and energy optimization.
Applications in HVAC
Our infrared sensors are ideal for a wide range of HVAC-related gas monitoring applications, including:
Refrigerant leak detection in air conditioning and refrigeration systems
Refrigerant leaks can impact safety, efficiency, and compliance. Modern refrigerants such as R-32, R-454, and R-290 may be flammable or have environmental risks if released. Leaks often occur around compressors, pipework joints, valves, and coil connections. Even small leaks can reduce cooling performance, raise energy costs, and damage equipment. They also contribute to greenhouse gas emissions and may result in regulatory penalties. Operators can detect issues early by installing sensors close to potential leak points. Integrated with alarms or ventilation systems, this monitoring helps prevent costly downtime and ensures compliance with F-gas and other safety standards.
Recommended Products

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 monitoring in air handling units and mechanical rooms
Air handling units, mechanical rooms, and chiller systems are common points for hydrocarbon or refrigerant leaks. In air handling units, leaks may enter through ducts or dampers, while compressors and pipe joints are often the source in mechanical rooms. If left undetected, these gases can build up, creating fire or explosion hazards and reducing system efficiency. Infrared gas sensors provide reliable, real-time monitoring in these critical areas. When connected to building management systems, alarms and ventilation can be activated automatically, helping to protect occupants and keep HVAC systems running safely.
Recommended Products
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 level detection in enclosed spaces to maintain air quality
Monitoring CO₂ is key to maintaining healthy indoor air quality. High CO₂ levels are common in classrooms, meeting rooms, gyms, and offices where ventilation is often stretched. Elevated concentrations can lead to drowsiness, headaches, and reduced concentration. Infrared CO₂ sensors provide continuous monitoring, allowing ventilation to be adjusted in real time. This improves comfort and well-being and reduces energy waste by introducing fresh air only when needed.
Recommended Product
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 control systems and energy recovery ventilators
Gas sensors are essential in making HVAC systems smarter and more efficient. Real-time measurements of gases like CO₂ enable demand-controlled ventilation, so airflow matches occupancy and air quality. Energy recovery ventilators also use gas monitoring to balance recirculation with fresh air, ensuring comfort without wasting heating or cooling energy. Sensors can highlight system inefficiencies early, reducing maintenance costs and keeping performance at its best.

High-resolution, temperature-compensated sensing for refrigerants. Supports smart HVAC control by enabling accurate, real-time monitoring for energy-efficient ventilation and system optimisation.
Ventilation safety systems for confined spaces and occupancy-based air management
Confined areas such as mechanical rooms, crawl spaces, and ceiling voids can trap refrigerants, hydrocarbons, or CO₂ if leaks occur. Gas sensors provide early warnings, ensuring these spaces remain safe for personnel. Gas monitoring also supports smart air management in buildings with variable occupancy, such as lecture halls or meeting spaces. By adjusting ventilation based on CO₂ levels, operators can avoid over-ventilation, which wastes energy, and under-ventilation, which compromises air quality.
