Patented Rectifier Technology
- significant climate separation efficiency (90%)
- excellent downward penetration
- laminar air flow
- air curtain warmth benefits the indoor climate
|Without rectifier: large air displacement||With rectifier: perfect climate separation|
Because of the difference in temperature between inside and outside areas, air always moves in the vicinity of an open door: warm air streams in and cold air streams out. The patented rectifier ensures that the air turbulence caused by the fans is transformed into a laminar air stream. The air stream reaches the floor at a much lower air speed than air curtains without the rectifier. The tight air stream prevents cold air from streaming out. This achieves a climate separation efficiency of over 90%.
