Station ventilation on right track

Natural and hybrid ventilation solutions manufacturer Passivent has supplied nine bespoke Aircool ventilators as part of a new fully enclosed, glazed footbridge spanning the railway track at the upgraded York Street station in Belfast.

The footbridge, part of a £17m project at the station, was designed by Gregory Architects. Working alongside mechanical and electrical consultant Semple & McKillop and mechanical sub-contractor Alufix Facades, Passivent manufactured the bespoke Aircool ventilators to integrate within the curtain walling of the footbridge. The units complement the aesthetics of the project perfectly, while controlling the temperature and CO2 levels within the glazed footbridge to prevent overheating, 

Alufix Facades installed the Aircool units, which Passivent supplied with externally accessed 24V actuators to modulate the motorised dampers. The externally fitted actuators allow for ease of maintenance as the steel structure within the footbridge was installed 10mm away from the internal cover grilles, meaning access from the inside was not possible. The actuators provide controlled air intake and extract via the Building Management System.

Designed to work with all forms of wall construction, curtain walling and window profiles, Passivent’s Aircool ventilators have excellent weatherability which means they can remain open even in adverse weather conditions. They offer excellent airtightness performance when closed and both louvres and grilles can be colour matched to any RAL or BS colour.  BIM Objects are available for both window and wall versions.
