  • Application
  • Description

Application

  • 2-pipe or 4-pipe heat exchangers enable good comfort levels
  • Inducing displacement flow
  • Energy-efficient solution since water is used as a medium for heating and cooling
  • For new buildings and refurbishment projects
  • Installation under the sill
  • Typical installation locations include offices and meeting rooms

Special characteristics

  • Air-water heat exchanger as 2-pipe or 4-pipe system, with G½" union nuts and flat seals
  • 4 levelling feet (optional)
  • Installation into a frame as an option
  • Condensate drip tray with condensate drain
  • Easy filter change with quick release fasteners, no tools required
  • Compact construction, hence particularly suitable for refurbishment projects

Variants

  • Traungasse project (Vienna, Austria)
  • Bennigsenplatz project (Düsseldorf, Germany)
  • Laimer Würfel project (Munich, Germany)

Construction

  • Powder-coated RAL 9005, black, gloss level 70 %
  • P1: Powder-coated in any other RAL colour, gloss level 70 %

Useful additions

  • Modular control system X-AIRCONTROL, specially for decentralised ventilation systems
  • Connecting hoses

Construction features

  • 1 energy-efficient EC fan with low specific fan powers, SFP = 1 according to EN 13779
  • The supply air is discharged to the room as an inducing displacement flow from the lower front part of the unit

Materials and surfaces

  • Casing, filter chamber cover, fans and levelling feet are made of galvanised sheet steel
  • Heat exchanger with copper tubes and aluminium fins
  • Casing is powder-coated RAL 9005, black, or in any other RAL colour
  • Mineral wool lining to DIN 4102, fire rating class A, faced with glass fibre fabric as a protection against erosion, effective with airflow velocities up to 20 m/s
  • Closed cell sealing strips

Functional description

Decentralised secondary air units dissipate cooling loads and heat loads.

The room air is taken in by an EC centrifugal fan and passes through a filter fleece. The air is subsequently heated or cooled by the heat exchanger and eventually supplied to the room as an inducing displacement flow.
