Tunnel/Metro
Due to the limited connection to the atmospheric environment, natural ventilation alone is insufficient to meet the rigorous ventilation requirements of tunnels and underground roads. Sun Yeh offers fire and smoke damper actuators that are applicable for normal operation such as temperature, humidity, and indoor air quality controls or smoke extraction in case of fire to ensure the safety and comfortability of the environment in tunnels and stations.
Our OM series quarter-turn and S series spring return quarter-turn electric actuators are suitable to be used in ventilation systems, smoke extraction systems, or emergency shutdowns to control smoke.
- Ventilation Challenge: Restricted natural airflow in tunnels and underground metros leads to poor air quality and increased risks during emergencies.
- Fire and Smoke Hazards: Rapid smoke spread in confined spaces can endanger lives and complicate evacuation procedures.
- Energy Efficiency Consideration: High energy consumption in ventilation and safety systems is a growing concern for operators striving for sustainability.
- System Reliability Issues: Maintaining reliable actuator performance in harsh conditions, such as high humidity, dust, and extreme temperature variations, remains a critical concern.
To address these pain points, Sun Yeh OM series quarter-turn electric actuators and S series spring return quarter-turn electric actuators offer exceptional durability, making them ideal for ventilation systems, smoke extraction systems, and emergency control in tunnels and stations. These actuators provide stable performance while meeting energy efficiency and safety requirements.
