Product Description

Trench heating with displacement ventilation. For draught-free ventilation.

Key Features

  • Displacement ventilation provides a comfortable room climate.
  • Effective cold air screening of large windows.
  • The room can be arranged independently of the heating system; the overall appearance of the building is not impaired.
  • Project solutions are available for all geometries with mitred corners, curved designs, column recesses or chamfered trenches.
  • A matching edge profile for a perfect design with every grille.

Your Benefits

  • Displacement air and façade
  • For the targeted supply ofconditioned displacement air.
  • Effective made-to-measure layered ventilation


  • Heating and cooling function combined in one unit.
  • Displacement air outlets allow for the low-turbulence supply of fresh air via large air outlets in the floor.
  • No draughts as air velocity is well below 0.3 m/s.
  • Additional perforated sliding panel between the displacement ventilation outlet and convector, which increases the heat output in problem areas.
  • Anti-torsion mechanism for heating connections prevents damage to the convector when fitting the valves; valves optionally available as accessories.
  • High-output Cu/Al convectors – 100 and 150 mm in depth.
  • Water connection: 1/2” room-side, displacement ventilation connection: Ø 70 mm or 100 mm room-side.

Areas of application/installation

  • Preferred when a high air volume and minor cooling output are required with a high room height.
  • Typical applications are office and administration buildings, meeting venues, restaurants, rooms with high glass façades and where air quality is likely to be poor.
  • Trench height of 130, 180 und 230 mm, minimum installed height of 140 mm; futher dimensions on request.
  • Overall frame width of 272, 310, 340, 400 and 420 mm; other dimensions within this range on request.
  • Minimal trench length: 1100 mm.

Also good to know

  • Supply lines can be run within the raised floor.
  • High quality of hygiene through the displacement of pollution, such as bacteria, pollen, etc.
  • Technical air volume/heating tests were carried out by the research company HLK at the University of Stuttgart.
