Wadham College - Oxford

Configuration: Supply air island canopy
Materials: Type 304 Stainless steel
Filters: Superstream Baffle type filters
Ultrastream UV Filtration system

During the redevelopment of Wadham College in Oxford the ventilation system was by far the most challenging aspect of the project.

The existing kitchen had a stone vaulted ceiling of architectural merit and English Heritage would not allow new structural fixings to be used to support the large island canopy.

To avoid this problem Britannia designed an integral stainless steel structural support framework, with vertical legs which run down the service distribution unit. The whole assembly is therefore a self supporting structure, reducing the load on the listed ceiling and allowing the project to proceed.

To house the mechanical services that feed the cooking equipment, Britannia also manufactured a custom designed service distribution unit complete with access doors and vertical risers which interface with the canopy above whilst also concealing the structural support frame.

To ensure grease and odours are removed from the exhausted air prior to discharge, the system also benefits from an Ultrastream UV filtration system, which breaks down the remaining grease and odour particles by using high intensity ultra violet light. Minimising maintenance and fire risk at the same time.
