Rectifier

All Biddle air curtains (SensAirCITY,  DoorFlowIndAC2IsolAir and MAT)  are equipped with the patented rectifier technology. This results in the following advantages: 

  • 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


High yield
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%.
