Physics ensures that different air masses in any heavily frequented building will be balanced out. Air that has previously been heated at great expense escapes through doors. The task of an air curtain system is to offset the unpleasant influx of cold air with a counter current. To do so, the volume flow, speed, temperature and momentum must correspond to the levels of the incoming cold air.
Air curtain systems make considerable contributions to reducing energy costs - up to 80 % with the Teddington CONVERGO® system.
Visitors to a shop that is at the right temperature demonstrate far greater willingness to spend time and money there.
Ultimately the saving also reduces energy consumption, which is good for the environment.
For example, sealing off unpleasant smells or dust development in industry. In addition, a good indoor climate reduces the incidence of staff sickness.
