  • Application
  • Description

Application

  • Ventilation and extract ventilation of rooms, preferably rooms with a depth up to 6 m
  • 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
  • Vertical installation on the façade or on an external wall
  • Typical installation locations include offices and meeting rooms

Special characteristics

  • Motorised shut-off dampers for fresh air and exhaust air, normally closed (NC) in order to prevent uncontrolled airflows
  • 4 levelling feet
  • Acoustically optimised EC fan
  • Heat exchanger as 2-pipe or 4-pipe system, with G½" union nuts and flat seals
  • Meets the hygiene requirements of VDI 6022
  • Filter class: F7 for fresh air
  • Easy filter change with quick release fasteners, no tools required
  • Condensate drip tray with or without condensate drain
  • Secondary air addition by means of TROX Compact controller
  • Compact construction, hence particularly suitable for refurbishment projects
  • Demand-based ventilation is possible by means of monitoring the room air quality and with dedicated control equipment

Variants

  • Feldbergstraße project (Frankfurt, 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

  • Energy-efficient EC fan with low specific fan powers, SFP = 1 according to EN 13779
  • Mechanical self-powered volume flow controller to limit the fresh air flow rate and add secondary air if necessary
  • Motorised shut-off dampers for fresh air and exhaust air, normally closed (NC) in order to prevent uncontrolled airflows
  • 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
  • F7 filter medium made of moisture-resistant glass fibre paper (certified by Eurovent)
  • 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 supply air and secondary air units ventilate the room and dissipate cooling loads and heat loads.

An EC centrifugal fan takes in the fresh air which then flows through the motorised shut-off damper, the volume flow limiter and the F7 filter.

If necessary, the air is heated or cooled by the heat exchanger before it is discharged to the room as an inducing displacement flow.

If necessary, secondary air is added to the fresh air in order to increase the thermal output.
