Ultrastream UV Filtration

The Defence Food Services School at Worthy Down, Winchester, provides training for a wide range of catering skills to the Army, Royal Navy and the Royal Air Force. DFSS has been widely recognised as the largest UV kitchen ventilation project in the UK.

The two storey facility at Worthy Down, has been redeveloped to provide 14 large commercial kitchens requiring a total of 84 ventilation canopies, installed in a 15 week programme.

Britannia, working closely with PKL incorporated Ultrastream UV filtration, which provides secondary grease and odour removal, reducing the whole life costs through lower maintenance and also reducing the fire risk, protecting the asset.

The UV lamps located within each canopy break down organic matter within the grease and odours by a combination of photolysis and ozonolysis.

During the design process it became apparent that the existing roof structure would not support the weight of large ventilation canopies, this problem was solved by the use of structural ground support frames, designed and installed by Britannia. All the canopies on the project stand on their own feet, removing the need to reinforce the fragile roof structure.

With so much cooking equipment on one project, the routing of services to equipment needed to be addressed. Britannia designed and installed services distribution units that safely route the gas and electrical services to the appliances, sometimes working around structural columns to retain an easily cleanable surface.
