UK based operations manufacturer Howden Calidair recently delivered high integrity fire dampers for the new Bangkok Metro in Thailand. Howden Systems, the Dutch branch, secured the contract for tunnel ventilation systems, including fans, silencers and the Calidair dampers for nine stations and five ventilation shafts on the North sector.
The Calidair dampers are used for fan isolation, draught relief and under platform exhaust. Rated at 2500C for one hour they can operate as part of a smoke management system in the event of a fire. Constructed in modular form for ease of assembly, they have a two hour fire rating in accordance with British Standards part 20. The dampers are manufactured in galvanised mild steel with aerofoil section blades for low pressure drop, the design enables low leakage rates to be achieved, critical for smoke management in a fire situation.

Osborne Alliance Ceramicsteel panels are the backbone of a system. No horizontal joints create an easy to service, low maintenance sealed tunnel lining said to provide optimum performance and exceptional total life costs.
Panels of over six metres can be quickly and mechanically lifted into place using suction pads and fixed via easy to clean vertical joints. This does away with the rapid corrosion and water ingress problems associated with horizontal joints, particularly in wet tunnels. Double sided Ceramicsteel panels allow water to flow down the back and gather in gutters at the bottom, eliminating a costly dripshed.
Bespoke cleaning equipment allows more effective single path cleaning, with no need for tunnel closure, and eradicates the problems of staining and streaking from horizontal joints. Ceramicsteel is generically vitreous enamel and provides the most cost-effective cladding of this type. According to Mark Dunleavy, works manager of contractor Fitzpatrick, "This appears to be one of the few systems that tackles, head-on, the problems of cleanability…."

With international offices, Belgium based lighting specialists Schréder Group provide solutions to suit all tunnel illumination requirements.
Schréder recently worked on the 1.6km twin-bore Cointe tunnel providing basic lighting and boost lighting. The FV-1 from Schréder’s FV range was selected for basic lighting. Made of aluminium and glass the unit offers symmetrical light distribution from a 49W T5 16mm tube fluorescent lamp. The FV-1’s are installed in an almost unbroken line along the tunnel above the road centre line. Fitting tunnel geometry, it maximises photometric efficiency and balances the luminous flux distribution between the walls and roadway. A dimmer is included allowing 100% light at night and 25% during the day.
The boost lighting system utilises the Schréder AF4 luminaries installed in parallel to the FV-1’s. The AF-4’s are fitted with 250 or 400W high pressure sodium lamps and have three electrical feed circuits to achieve either very brightly lit, light or subdued conditions. Also available from Schréder is the Luminance Meter, a tool for management of lighting levels in the tunnel entrance, linings for visual comfort and an upper reflecting strip to show light emitted by brake lights outside the field of vision.

The Vienna metro system is benefiting from new fans supplied by Woods Air Movement of Colchester, UK; EN ISO 9001 registered manufacturer of ventilation fans with representatives worldwide.
The company’s Jetfoil, JM and JG Aerofoil fans are providing the air movement solution on the metro’s new 14km long U3 extension that includes 21 stations. The fans are taking care of under platform and smoke extract ventilation combined with general ventilation of the station concourses. The Jetfoil fans have been enhanced to improve efficiency ranging in diameter from 400 to 1600mm and are suited to the longitudinal ventilation of metros. The axial JM aerofoil fans range in standard diameters of 315mm – 3150mm, usually supplied as unidirectional they can be specially designed as 100% reversible flow models. Both models are certified for temperatures of up to 400°C/2 hours.
