The Britomart Rail Station project was a landmark project and highlighted the breadth and depth of Cooke Industries’ product range, incorporating industrial dampers, displacement diffusers, ductwork, attenuators, and acoustic doors with a combined $2.5M order value.
The Opus Consultants’ design was the largest displacement ventilation project in New Zealand, with over 200 custom diffusers handling over 182m 3/s. These specialised TROX displacement diffusers were custom designed to suit the strict architectural requirements and locally manufactured in 316-BA polished stainless steel. Ranging in size from 300 diameter x 1200mm high to 700 diameter x 2500mm high, they incorporated special bases to withstand crowd loading and vandalism; emergency light fittings; glass balustrade supports; signage; and were designed to be self-balancing - no mean task when the supply duct runs were some 250m long. The designs were rigorously tested to meet the projects aerodynamic, acoustic, and structural requirements.
