Air Curtains Nedfon FM4509DY

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.

Application of Air curtains Nedfon FM4509DY

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.
