  • The air handling units are the fully featured ventilation units with heat recovery for air filtration, fresh air supply and stale air extract.
  • The casing is made of 15-26 mm thick expanded polypropylene (EPP), possessing high heat- and sound-insulating properties.
  • Supply and extract air flows are purified through G4 panel filters.
  • For extra supply air filtration a F8 filter is available as a specially ordered accessory.
  • High-efficient electronically commutated motors with external motor and impeller with backward curved blades.
  • The VUT 270 V5B EC units are equipped with a counter- flow polystyrene heat exchanger.

  • The VUE 270 V5B EC units are equipped with an enthalpy counter-flow heat exchanger.

  • The VUT/VUE 270 V5B EC units are equipped with a bypass for summer ventilation (cooling of the premise with a cool outside air).
  • For VUT/VUE 270 V5B EC A14 the freeze protection is realized by means of shutdown the supply fan.
  • For VUT/VUE 270 V5B EC A21 the freeze protection is realized by means of turning the preheater (available as an accessory) on.
  • The units are designed for wall and floor mounting.
  • The access for unit and filter maintenance is available on the right and left side.
  • The VUT/VUE 270 V5B EC A21 units are equipped with control system.
  • The A21 controller allows integrating the unit into the Smart Home system or BMS (Building Management Systems).
  • The unit is controlled via Wi-Fi by means of the VENTS Home mobile application that must be downloaded.
  • The VUT/VUE 270 V5B EC A14 units are equipped with integrated control system and wall-mounted sensor control panel A14 with LED indication.

Calculation of air temperature at heat exchanger outlet:

t = toutd + khr * (textr - toutd) / 100,

toutd is outdoor air temperature [°C]
textr is extract air temperature [°C]
khr is heat exchanger efficiency (according to the diagram) [%]
