Air curtains

The perfect temperature barrier for your gates

  • Industrial gates with a height up to 5 m
  • Housing made of galvanized sheet steel, powder-coated including slats
  • Direct driven centrifugal fan
  • Energy savings up to 30% through minimizing the cold air inlet
  • Low investment costs due to simple and quick installation
  • Fast amortization
  • Comfort gain due to an even temperature level in the building
  • Low maintanance effort
  • Fast and smooth goods traffic by minimizing downtime at the gates
  • The air curtains do not require a heating medium (electric, hot water)

Solution for thermal gate problems

On cold winter days, people who are in charge of buildings or halls tend to keep the gates closed as much as possible. Because of the temperature difference between the inside and outside, a lot of cold air comes into the building whenever the gates are opened. This sudden flow of cold air is perceived as uncomfortable and annoying by the workers. Furthermore, the heating system needs to work more which lets the heating cost rise up rather quickly. Another problem that arises with closing and opening the gates is the stillstand for goods traffic. The solution to those problems is the air curtain made by nordluft!

With our air curtain, you create a temperature barrier that keeps the warm air inside and the cold air outside. Energy losses are therefore reduced to a minimum which also lowers the cost for heating. The money you invest for the air curtain is made up for rather quickly by the savings you make in the long-term.

Situation 1:

Open gate and not air curtain

The difference in pressure causes the cold external air (blue) to move inside the building and to push the warm inside air (red) to the ceiling.

Situation 2:

Open gate and turned-on air curtain

The previously described process in situation 1 is prevented. Important for that is the correct air velocity. If the air speed is too high, cold air can get in due to air circulations. On the other hand, if the velocity is too low, it is not possible to create a proper barrier since the air curtain cannot rach the floor.
