Duct gas detector
Ensure air quality and safety with advanced gas detection technology while protecting your facility with a duct gas detector for reliable fire hazard monitoring
What is it and how does it work?
A duct gas detector is a specialized safety device engineered to identify dangerous gases circulating through a building’s ventilation system. These systems are indispensable in industrial plants, commercial buildings, and other high-risk environments where undetected gas leaks could lead to fire hazards, explosions, or exposure to toxic substances.
These detectors continuously sample the air in the ductwork, using sensitive sensors to detect even minimal traces of hazardous gases. When a threat is identified, the system triggers immediate safety protocols, which may include stopping the airflow, activating alarms, or initiating emergency ventilation and gas suppression measures.


Types of gases
With the quality of Made in Italy, each SV Sistemi di Sicurezza’s duct gas detector is equipped with the latest technologies to ensure precision and rapid response. We combine high-sensitivity sensors designed to adapt to different types of gases and the most demanding environments:
- Air quality control: detects carbon dioxide using NDIR sensors, ensuring continuous monitoring of ventilation and HVAC systems;
- Industrial safety: detects methane and other flammable gases with catalytic sensors, preventing potential explosions and fire hazards;
- Parking garage and mechanical room: monitors carbon monoxide levels through electrochemical sensors, protecting enclosed environments from toxic gas accumulation;
- Cold storage and food processing facilities: detects ammonia using electrochemical sensors, enabling early leak detection to ensure safety and product integrity.
Choosing the right duct gas detection system
Selecting the most effective duct gas detector requires an assessment of your facility’s specific risks and operational needs. The type of gases, ventilation complexity, and facility size all determine the best detection solution.
With over 30 years of experience, SV Sistemi di Sicurezza provides Made in Italy tailored solutions that comply with the highest international safety standards. Our expertise ensures that your duct gas detection system is optimized for maximum reliability and efficiency, keeping your environment safe from undetected gas leaks.
