Door air curtains: save money quickly with a comfortable indoor climate

Door air curtains: save money quickly with a comfortable indoor climate

Who’s not experienced the flow of warm air coming from above open doors or doorways? Door air curtains are being used there. It is inevitable that doorways are frequently opened and closed, or even remain open for longer, particularly in the industrial sector. Door air curtains are the units of choice in these cases to efficiently protect doorways during the winter months from the ingress of cold air, and retain the valuable heat indoors.

How does fresh air enter a room?

How does fresh air enter a room?

We have all become aware of how important fresh air is, at the very latest since the outbreak of the coronavirus pandemic. There is now greater awareness of the need for regular ventilation and all sectors are now paying attention to it. We now know that the supply of fresh air into a room dilutes the concentration of pathogens and significantly reduces the risk of infection by viruses.

However, another important factor is the reduction of the concentration of CO2 in the room air and thus the air we breathe. Too high a CO2 content in the air causes fatigue and reduces a person’s ability to concentrate.
