A systematic metro ventilation design ensures that temperature, relative humidity, airflow velocity, and air cleanliness inside passenger compartments remain within specified ranges. In emergency situations, it guarantees operational stability, protects personnel safety, and enhances passenger comfort.
1. Fast response time for reverse switching – capable of switching to smoke extraction mode within 60 seconds of a fire outbreak.
2. High-temperature resistance – can operate normally for more than 2 hours at 280 °C.3.
3. Ensures tunnel airflow during peak passenger hours while removing harmful gases such as CO, NO, and NO₂.
4. System operating noise ≤ 70 dB, meeting requirements for public areas such as station halls and platforms.
Using CFD (Computational Fluid Dynamics), the company has taken the lead in developing high-flow, high-pressure, high-efficiency, low-noise metro ventilation and air handling equipment in China. While improving operational efficiency, the equipment also features reduced size and weight, making it a complete substitute for imported products.
To date, the company’s metro ventilation and air handling equipment has been successfully applied in over 60 metro lines both domestically and internationally.
