Tunnel Ventilation

Driven by falling costs and advancements in technology, the tunnelling sector is growing rapidly. Around the world, increasingly ambitious underground projects are being commissioned, engineered and completed – and when it comes to tunnel applications, each operation poses unique fire and smoke safety challenges.

Typical challenges

It is crucial that underground environments remain well ventilated, and that air quality is maintained for both users and personnel. HVAC equipment plays a pivotal role in ensuring safety during day-to-day operation as well as in emergency situations.

Why choose Halton-Flamgard

Tunnel dampers help maintain volumetric airflow in tunnel applications, so that air quality remains in line with acceptable standards. In the event of a fire, tunnel dampers facilitate the removal of smoke and other toxic gases, allowing time for controlled evacuation and entrance of emergency services where necessary.
Effective fire dampers also help to prevent the spread of flames through ductwork, minimising damage and danger wherever possible.
Flamgard’s CFD-02TM tunnel damper has been designed specifically for underground applications, offering a series of invaluable credentials:

• Guaranteed to perform up to 400oC for up to 2 hours

• High-temperature pressure tested: 400oC for 1 hour at 4,000pa

• Endurance tested for 100,000 electrically actuated cycles

• Complies with fire integrity testing UL555 and BS746, and EN1751 qualified for low pressure drop and low case/blade leakage

• Low Demand SIL 4 rating
