As part of the refurbishment of the Kingsway Hall Hotel in London’s Covent Garden, a Dimplex ARC architectural air curtain has been installed to prevent draughts from the large entrance doorway with automatic sliding doors. These 2 m-high doors open into the main reception and adjacent bar area, and the potential for uncomfortable draughts was recognised by general manager Laszlo Nyari, who consulted with John Kindell of JWK Electrical, the hotel’s electrical contractor.
