In a contract worth £100 000 Trox (UK) has supplied 77 chilled beams to help transform the former prison at Oxford Castle into a luxury hotel.

The former cells of the prison's A-Wing have been converted into opulent bedrooms for the Malmaison hotel. Each bedroom is fitted with two Trox passive chilled beams. These were custom-designed to suit the surroundings and optimise comfort cooling. They are constructed of aluminium extrusion, with perforated faces profiled to fit the dome-shaped ceilings in the building.

Trox worked closely with developer The Osborne Group/Oxford Castle, consultant Cameron Taylor Brady, architect Architects Design Partnership and m&e contractor Norstead, to develop the SPL TCB-EB exposed passive chilled beams. It manufactured sample beams and built a mock-up of one of the hotel rooms at its Thetford test laboratory to enable the thermal performance to be assessed prior to installation. The factory-assembled beams were then delivered to site.

Trox also supplied fan coil units, attenuators and grilles for the project.
