Door air curtains with heated and ambient air streams for screening

Benefits

  • Energy-saving by patented Tandem technology
  • Coanda effect between the primary and warm air streams
  • Self-optimising back-up air stream when speed changes
Configurator
  • Short delivery times for our standard ProtecTor door air curtains
  • Effective cold air screening across open industrial doorways
  • Energy savings of up to 38% compared to conventional systems
  • Fast return on investment with Kampmann door screening
  • Improved use of space close to the doorway
  • Official title of property: European Patent EP 1462730 A1
  • Coanda effect to improve the penetration depth of both air streams:
    • Ambient air stream pulls the warm air stream
    • Improved screening and higher installation heights
  • Ambient air stream acts as a back-up air stream: it automatically optimises as the fan speed changes to match the warm air stream
  • Adverse weather stays outside, thanks to the enhanced penetration depth between two parallel air streams of different temperature
  • PowerKon heat exchanger consisting of hollow copper tubes with profiled aluminium special fins

Technical details:

  • KaControl system or electromechanical controllvia stage switch combined with door contact switches
  • Integration in KaControl networks or building automation systems, such as BACnet, Modbus or LON possible
  • Special designs on request

The energy-savings are achieved thanks to the unheated primary air stream with its lower thermal up-current. The primary air stream screens the warmer air curtain and together they ensure that cold air from outside does not penetrate into the room and warm air cannot escape out.

 

The penetration depth and screening effect are both increased by the contraction of the primary air stream and the warm air stream without this needed additional energy. This also means that the units can even be fitted at a greater height.

 

There is only one water and electrical connection. This along with sensibly arranged fixing points saves installation time.
