Ventilation for tunnels and underground transport systems.
In order to remove build-up of heat and contaminants, tunnels must be properly ventilated both during construction and operational use to ensure the safety and comfort of passengers and workers.
Tunnels and Metro Systems Applications
Road and Rail Tunnels
Good ventilation is an essential part of the planning process for the transport sector, with a need for series-produced fans operating with high reliability for safety and passenger comfort.
Metro and Underground Tunnels
Ventilation systems for underground stations should provide continual air exchanges to remove the build-up of excess heat and contaminants within occupied spaces. Under emergency conditions they serve to remove smoke and maintain the safety of escape routes.
Rolling stock have a varied range of ventilation requirements, including saloon and cab ventilation for the comfort of operatives and passengers, as well as for engine and electrical cooling systems.
It is critical that the ventilation system must operate effectively during emergencies in order to allow a safe evacuation.
