  • 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
  • Installation under the sill
  • Typical applications include classrooms in schools, playrooms in daycare facilities, smaller meeting rooms and offices with a high air change rate

Special characteristics

  • Motorised shut-off dampers for fresh air and exhaust air, normally closed (NC) in order to prevent uncontrolled airflows
  • Demand-based ventilation and extract ventilation is possible by means of monitoring the room air quality and with dedicated control equipment
  • For demand-based ventilation
  • Recuperative heat recovery with motorised bypass
  • Decentralised ventilation unit for high volume flow rates
  • 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

Variants

  • SCHOOLAIR-B-0 – volume flow rates: 150, 200, 250 and 320 m³/h, with cross flow plate heat exchanger for heat recovery
  • SCHOOLAIR-B-HV – volume flow rates: 200, 250, 300 and 350 m³/h, with cross flow plate heat exchanger for heat recovery
  • SCHOOLAIR-B-HE – volume flow rates: 150, 200, 250 and 320 m³/h, with counter flow plate heat exchanger for heat recovery

Construction

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

Accessories

  • Outer casing made of wood, with integral supply air and extract air grilles

Useful additions

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

Construction features

  • 2 energy-efficient EC fans with low specific fan powers, SFP = 1 according to EN 13779
  • Fresh air flow rate up to 350 m³/h, depending on construction variant
  • Cross flow or counter flow plate heat exchanger
  • 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
  • Extract air is taken in to the upper 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
  • Plate heat exchanger (heat recovery) made of aluminium
  • 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 extract air units for room ventilation and extract 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 recuperative heat exchanger in order to protect 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 protects 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.
