Customised air curtain for revolving-door is carefully concealed
JS Air Curtains has supplied four custom air curtains for the stylish refurbishment of the 11-storey 110 Cannon Street in the City of London. The architect specified air curtains, but with the provisos that no appliances be located above the rotating entrance door or visible through the glass facade of this 6500 m2 building.
Engineering consultant AECOM called in JS Air Curtains, and the company’s concealed design proved the ideal solution.
Steve Lockwood of AECOM said, ‘This is an unusual application for air curtains that would traditionally be sited above the revolving doors. However, JS was able to adapt the air curtains to overcome any difficulties that concealing them in walls might cause. The air curtains have been installed for several months now and appear to be working very well.’
Each of the four 1.5 m-high air curtains draws air into the back and discharges it from the front. They are connected in pairs to form two 3 m-high towers that are concealed in walls on either side of the main doorway onto Cannon Street. These air curtains prevent the glass revolving door acting like a slow-moving fan and bringing in cold air with every turn.
