SUPPLY AND EXTRACT AIR UNIT WITH HEAT EXCHANGER AND HEAT RECOVERY UNIT, SECONDARY AIR OPTION, FOR VERTICAL INSTALLATION ON AN EXTERNAL WALL, E.G. ADJACENT TO A WINDOW

Ready-to-operate decentralised ventilation unit for comfortable room temperature control and ventilation of rooms

  • Acoustically optimised EC fans with low specific fan power, acc. to DIN EN 16798-3 SFP = 0
  • Cross flow heat recovery unit (heat recovery efficiency 61 %)
  • Highly efficient heat exchanger for heating and cooling as 2-pipe or 4-pipe system
  • Heat exchanger connection is on the right side of the room
  • Condensate drip tray with condensate drain
  • Heat recovery all year round (condensate drainage required on site)
  • Unit floor space approx. 0.13 m²
  • Reduction of fine dust and pollen contamination due to integral filters that conform to VDI 6022 3 filter class ISO ePM1 65% / ISO coarse 50%
  • Service-friendly maintenance cover for filter changing and cleaning the heat recovery system
  • Motorised shut-off dampers, normally closed (NC)
  • Automatic switching to secondary air mode (based on air quality) 

Optional equipment and accessories
  • Control system FSL-CONTROL III, specially designed and modularly constructed for decentralised ventilation systems
  • Wood panelling covers in various colours, with TROX ventilation grilles for supply and extract air (self-assembly kit)

Application

Application

  • 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 for heating and cooling
  • For new buildings, refurbishment projects and revitalisation 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, normally closed (NC) in order to prevent uncontrolled airflows
  • Recuperative heat recovery unit, including bypass damper with electric variable actuator
  • 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, G3 for extract air
  • Easy filter change with quick release fasteners, no tools required
  • Condensate drip tray with or without condensate drain
  • Compact construction, hence particularly suitable for refurbishment projects
  • Demand-based ventilation and extract ventilation is possible by means of monitoring the room air quality and with dedicated control equipment
  • 4 levelling feet
  • Automatic switching to secondary air mode (only with an air quality sensor) if the room air quality (measured with the integral VOC sensor, for example) is between the previously defined range. The fresh air damper closes, the self-powered secondary air damper opens and the extract air fan is switched off. The unit always starts in secondary air mode, which is more energy efficient.

Nominal sizes

  • 396 × 1800 × 319 mm (B × H × T)

Technical information

  • FUNCTION
  • TECHNICAL DATA
  • ORDER CODE

Decentralised supply and extract air units for room ventilation and for dissipating cooling loads and heat loads. An EC centrifugal fan takes in the fresh air which then flows through the motorised shut-off damper and the F7 filter. Once the fresh air has passed the fan, it flows through the recuperative heat exchanger for heat recovery; it is possible to bypass the heat exchanger in order to pect it, or when it is sensible with regard to energy efficiency. If necessary, the air is heated or cooled by the heat exchanger before it is discharged to the room as a displacement flow. The extract air first passes a G3 filter (that pects the unit), then flows through the heat exchanger (for heat recovery), the extract air fan and the motorised shut-off damper before it is discharged to the outside as exhaust air. Automatic switching to secondary air mode (only with an air quality sensor) if the room air quality is sufficient. The fresh air damper closes, the self-powered secondary air damper opens and the extract air fan is switched off. The unit always starts in secondary air mode, which is more energy efficient.
