Warm air rises. We all know the physical effects of hot air: “hot air rises.” A law of nature that, above all, balloonists or glider pilots make use of. This effect does not just bring advantages with it. When doors are open, it leads to loss of heat.
These unpleasant consequences of thermal as well as cold air incidences are counteracted by our air curtains. The advantages for you: lower energy costs and higher comfort!
Warm, ascending air was used by the first air curtains systems on the always open doors of department stores in the 60s. One might remember, in this context, the famous picture of Marilyn Monroe above a Manhattan Metro ventilation shaft. The goal of the new technology was to protect the sales rooms from penetrating cold air. Air curtains are still good for this task today. Amongst other things. Only the airflow as such has adapted itself to the technical advances. Today, one shields top to bottom more comfortably. We have taken the principle of air curtain technology to extremes or better to its high point and we have developed many new installations. Almost everywhere, where differing |

In every heavily frequented building, physics does not allow for a decent balance of the air mass. Expensively heated air leaks through doors and gates.
The task of an air curtain system is for the unpleasant cold air flow K in the entrance area to come up against a counter flow H. Volume flow, speed, temperature and impulse have to be consistent with the cold air incidence.
Der Luftschleierstrahl R setzt sich aus den benötigten horizontalen und vertikalen Komponenten zusammen.
The air curtain stream R is made up of the necessary horizontal and vertical components.
With an EVOLVENT ® air curtain system from Teddington one controls the air blow-out angle exactly, the volume flow rate R and the speed V. Through this, counterforce H results as an opposing impulse to cold air flow K. |

More than just hot air.
We have brought the principle of air curtain technology one step further. It is amazing what has emerged:
Integrated energy saving:
Air curtain systems contribute substantially to energy cost saving. Up to 80% if using our patented EV OLVENT ® systems.
Integrated sales psychology:
Visitors show a much higher willingness to stay and buy in a shop where there is not an unpleasant draft.
Integrated environmental protection:
The user’s energy saving is reflected, at the end of the day, in a lower production of necessary energy. Good for the environment.
A good integrated climate
For example by removing unpleasant odours or dust in industrial situations. In addition, employee sickness is reduced significantly with an air curtain unit. The systems provide a consistently good climate.
