Air curtains do dual duty at Exchequer Court
JS Air Curtains has installed two vertically mounted stainless-steel Rund air curtains at Exchequer Court, a multi-storey office block in St Mary Axe, London. These air curtains provide the main heating source in the large, open atrium of the reception area and keep out draughts. The high ceiling of the atrium and the large revolving entrance door prohibited the use of air curtains suspended from the ceiling and required a high heating output to counteract cold airflow.
Building manager John Evans commented, ‘The massive cubic space of our entrance atrium was proving a challenge to heat because the revolving doors were acting as a huge fan, brining in cold air with every turn. The Rund air curtains, positioned vertically either side of the doorway, are able to cope with this, keeping out the draught and providing sufficient heating for our reception staff. We have had not complaints of cold over the winter season and have been able to maintain a low heat-output setting.’
Rund air curtains have an attractive cylindrical design and are available in five lengths from 1 to 3 m. Control options include thermostats, door-open sensors, outside-temperature sensors and timers. They can be heated by electricity of hot water, with outputs from 3 to 36 kW, or supplied as air-only models.
