Flexible Installation and Energy-Efficient cold room Air curtain Solution
Air Curtain Drums
For AS-K cold rooms, air curtain drums are available in sizes from ⌀250 to ⌀400.
For smaller or larger airflows, we offer standard models S. ⌀250, S. ⌀315, and S. ⌀400. We also have circular air curtain drums (C. ⌀250, C. ⌀315, and C. ⌀400) for specific installation requirements, as well as square and rectangular models (F.250, F.315, and F.400) to suit unique conditions. For installations with limited height, such as between a suspended ceiling and a doorway, we can design air curtain drums with a low overall height.
We also offer flexibility in installation. The spiral duct from the fan unit can be connected to any point on the air curtain drum, and the drum can be equipped with an extended nozzle for easy integration with suspended ceilings.
