Application of Nafuji FJ5509DY
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.
