- VFD/PLC Smart Control for Energy Efficiency
Tunnel Ventilation System
The Tunnel Ventilation System supplies fresh air to the tunnel face, exhausting hazardous gases and dust generated during excavation. In long tunnels and TBM projects, this system is critical to both worker health and safety, ensuring continuous air quality and safe operating conditions along the entire tunnel heading.
- Applications
- Tunnel Ventilation During Excavation
- Dust and Gas Extraction
- Airflow Control in Long Tunnels
- Oxygen Supply in Confined Underground Spaces
