X-CUBE SCHOOLAIR-B 

Supply and extract air unit with heat exchanger and heat recovery, secondary air option, for installation under the sill

Ready-to-operate decentralised ventilation unit that provides good comfort levels, used for the ventilation and extract ventilation of rooms such as classrooms in schools

  • Acoustically optimised EC fans with low specific fan power, SFP = 0 to EN 16798-3
  • Plate heat exchanger for heat recovery (air/air), including bypass with electric actuator
  • Highly efficient heat exchanger for heating and cooling as 2-pipe or 4-pipe system
  • Heat recovery all year round
  • Reduction of fine dust and pollen contamination due to integral filters that conform to VDI 6022 – F7 fresh air filter and G3 extract air filter
  • Easy filter change, no tools required
  • Condensate drip tray with condensate drain
  • Motorised shut-off dampers, normally closed (NC)
  • Installation without interruption to the operations of the respective school


Optional equipment and accessories

  • Modular control system FSL-CONTROL II, specially for decentralised ventilation systems
  • Demand-based fresh air volume, free cooling and night purge, depending on control strategy
  • Various fixing systems to fix the unit to the floor or wall
  • Variable heat recovery
  • Powder-coated RAL 9005 (black)

Application

Application

  • Ventilation and extract ventilation of rooms with a depth up to approx. 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
  • Installation under the sill
  • Typical applications include classrooms in schools, playrooms in daycare facilities, meeting rooms and offices with a high air change rate

Special characteristics

  • Decentralised ventilation unit for high volume flow rates
  • Motorised shut-off dampers for fresh air and exhaust air, normally closed (NC) in order to prevent uncontrolled airflows and the carry over of smoke
  • 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 variable bypass all year round
  • 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 condensate drain
  • Compact construction, hence particularly suitable for refurbishment projects

Construction features

  • 2 energy-efficient EC fans with low specific fan powers, SFP = 1 according to EN 13779
  • Fresh air flow rate up to 400 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 and the carry over of smoke
  • 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 powder-coated, black (RAL 9005)
  • 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

Standards and guidelines

  • Façade ventilation units of Type SCHOOLAIR-B conform to VDI 6035 and VDMA 24390
  • Hygiene certificate to VDI 6022
  • Heating/cooling fluid conforms to VDI 2035
  • Meets the requirements of EU directive 1253/2014 (ErP).

Maintenance

  • VDI 6022, Part 1, applies (Hygiene requirements for ventilation and air-conditioning systems and units)
  • The heat exchanger can be vacuumed with an industrial vacuum cleaner if necessary
  • It can also be cleaned with commercial, non-aggressive cleaning agents
