Your Benefits

  • 38 % energy savings usingTandem technology.
  • Minimal heating requirement withthe same penetration depth.
  • Valves (optional) can beconcealed behind the casing.

Technology

  • Coanda effect to improve the depth of penetration of the door air curtain.
  • Ambient air stream acts as a back-up stream.
  • Adverse energy-intensive turbulence occurs primarily between the outside air and the unheated ambient air stream.
  • Adverse weather stays outside, thanks to the enhanced penetration depth between two parallel air streams of different temperature.
  • High-performance copper/aluminium heat exchanger.
  • Easily removable air filter (grade G 2 in line with DIN EN 779); easy to clean by vacuuming or washing.
  • Anti-torsion mechanism for heating connections prevents damage to the heat exchanger when screwing in the valves; valves optionally available as accessories.
