First and foremost air curtains are designed to prevent a climate area (heated or cooled) from the influx of outside air through an open doorway.
The air curtains reduce energy costs by keeping heated or cooled air in the internal building atmosphere.
Efficient air curtains will save up to 80% energy looses across a doorway compared with a door without air curtain.
During the winter an air curtain creates a barrier that keeps out the cold air while in the summer the air stream keeps out the hot air from outside.
Bearing in mind the energy saved, the average payback time for an air curtain is between 2 and 5 years depending on usage and climate conditions.
Although doors are open the air curtain separates internal and external conditions
Insect air curtains are commonly used, when necessary, to stop insects from entering a buildings like food processing plants, bakeries, restaurants, hospitals, etc. Bugs in flight approaching will be stopped by a barrier of air too powerful to penetrate.
Air curtain stops flying insects entrance from the outside
You need to select the correct air curtain for insect repellent applications. A very powerful air jet along the all doorway is needed (stronger than standard applications).
Due to big temperature differences, it is highly recommended to install air curtains to reduce the energy losses when the door is open. The higher the temperature differences between inside/outside, then higher are the energy losses when a door is unprotected.
So the payback period of the air curtain is very short and then the energy/money saving is very high.
Not only we will save money avoiding air transfer through the door but also will keep the frozen goods in perfect condition and help to reduce defrost costs of the cold room.
Air curtains are the safest way to save lots of energy in cold rooms
For cold rooms and freezers air curtains are the safest way to protect the energy losses without any physical barrier that can create accidents or collisions on the doorway. For example, when plastic strip curtains are used the view across the doorway is limited and people or vehicles accidents occur, with compensation consequences. Besides it prevents bothersome and potentially dangerous fogging, humidity and ice formation in the door entrance area.
Always installed in the clean side of the doorway, air curtains act as a barrier against dust, particles and humidity.
