Ensuring Air Quality and Safety in Tunnels
Cvsair’s tunnel fans are engineered to provide exceptional ventilation in tunnels, ensuring air quality and safety. These robust fans are designed for both daily ventilation and critical fire safety scenarios. With a double-speed motor, they offer flexibility in operation, adapting to different ventilation needs. During normal operation, the fans operate at standard speed, while in case of a fire, triggered by carbon monoxide and smoke sensors, the speed doubles to rapidly exhaust harmful gases.
Key Features and Benefits
Our tunnel fans boast several key features, including a galvanized steel sheet casing (TS EN ISO 1461) for durability and corrosion resistance, a wire shield, and an integrated deflector for enhanced safety and performance. The outside terminal box simplifies installation and maintenance. Powered by a highly efficient IE2 motor with Class-H insulation and IP55 protection, these fans deliver reliable performance even in demanding environments. They are also EN 12101-3 certified, ensuring compliance with stringent safety standards.
Advanced Engineering and Performance
Cvsair offers comprehensive engineering services, including analysis reports and tunnel ventilation implementations, such as fan selection programs and CFD analyses. These fans effectively reduce harmful gases like carbon monoxide, nitrogen oxide, and particulates generated by vehicles. In the event of a fire, the fans expedite the removal of polluted air, directing it along the traffic flow towards the tunnel exit. This system provides ease of installation and minimizes downtime for maintenance and repairs. Available in F300 (300°C / 120 min) and F400 (400°C / 120 min) strength classes according to EN 12101-3, with diameters ranging from Ø560 to Ø1600 mm and thrust values up to 2300N. The protective wire shields against particles, and the integrated covers efficiently direct airflow. A protective coating layer and fire-resistant terminal boxes further enhance safety.
