Description
Description
DESCRIPTION
  • The air-handling units are the fully featured ventilation units with heat recovery for air filtration, fresh air supply and stale air extraction.
CASING
  • Made of high-quality polymer coated steel, internally filled with mineral wool layer for heat and sound insulation.
FILTER
  • Supply and exhaust air flows are purified through panel filters with filtering class G4 and F7, respectively.
  • Filters with G4 filtering class are used for supply and exhaust air purification in the VUT/VUE 250 VB EC units.
  • F7 filter is available as an option for supply air filtration.

FANS
  • The units are equipped with high-efficient EC motors with an external rotor and a centrifugal impeller with backward curved blades.
HEAT EXCHANGER
  • The VUT V(B) EC units are equipped with a counter-flow polystyrene heat exchanger.

  • The VUE V(B) EC units are equipped with a counter-flow enthalpy heat exchanger.

BYAPASS
  • The VUT/VUE VB EC units are equipped with a bypass for summer сooling.
FREEZE PROTECTION
  • In the VUT/VUE 160/350/550 VB EC A21 units it is possible to connect a preheater to protect the unit from freezing.
  • The VUT 250 VB EC A21 unit is equipped with a built-in preheater for frost protection.
MOUNTING
  • The units are designed for wall or floor mounting.
  • Access for maintenance of units and filters is possible from the right and left sides.
AUTOMATION
  • The VUT/VUE V(B) EC A21 units are equipped with a built-in automation system.
  • The A21 controller allows integrating the unit into the Smart Home system or BMS (Building Management Systems).
  • To control the unit via Wi-Fi, download the VENTS Home mobile app.
  • The VUT/VUE V(B) EC A14 units have an integrated control system with a wall-mounted control panel A14 with a LED indication.

Calculation of air temperature downstream of the heat exchanger:

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

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