With air curtains, building operators supplement their industrial space heating and cooling systems in an efficient manner and avoid unnecessary energy losses and unwanted draughts through doors and gates. For this purpose, Schwank offers various air curtain unit systems for almost every individual application.  The SchwankAir air curtains are suited for new buildings as well as for retrofitting.

Air curtains blow ambient air or heated air directly along the opened gate. This “curtain of air” separates the outdoor air from the indoor environment in the form of an invisible wall. Unpleasant draughts from the outside are therefore prevented by a system of air curtain units, enhancing employee satisfaction in a sustainable manner.

Air Curtains Eliminate Energetic Weak Points

Air Curtain Systems

Small Investment – Great Effect

Open doors and gates are often energy-devouring challenges to systems of efficient heaters and cooling units in the workplace. Valuable heat in winter and elaborately generated cold air in summer escapes at these points. The following holds true: the bigger the opening, the more drastic is the effect of uncontrolled exchange of ambient and outdoor air and the higher the probability that it will result in unpleasant draughts.

Those who keep these heat losses in check with the help of air curtains spare energy costs and enhance the work climate. For gates, Schwank, a leading expert in the manufacture of innovative energy efficient heating and cooling solutions, offers tailor-made products, including with regard to supplementing existing heating systems.

Reducing Heating Costs with Air Curtains

Air curtains blow ambient air or heated air directly along the opened gate. This “curtain of air” separates the outdoor air from the indoor environment in the form of an invisible wall. Unpleasant draughts from the outside are therefore prevented, which enhances employee satisfaction in a sustainable manner.

Important with a view to energy prices: facility operators save energy costs and the operating times of the heating system are reduced significantly.

More Comfort for Your Hall

Like a curtain, Schwank air curtain systems prevent the penetration of cold or warm air. Conversely, they also block the unwanted volatilisation of, for example, conditioned air.
