Description
DESCRIPTION  
  • The air-handling units are the fully featured ventilation units with heat recovery for air filtration, fresh air supply and stale air extract.
  • During operation the extract air heat is transferred to the supply air stream by the highly efficient plate heat exchanger.
  • The units are designed for energy efficient ventilation of cottages and flats and are compatible with round air ducts (Ø 125, 160 and 200 mm).
FILTER FANS
  • Supply and exhaust air is purified in panel filters with filtering class G4 and F7, respectively.
  • Filters with G3 filtering class are used for supply and exhaust air purification in the VUT/VUE 200 VB EC units.
  • Supply air in the VUT/VUE 250 VB EC units is purified by the G4 and F7 filters.
  • Exhaust air is purified by the G4 filters.

  • The units are equipped with high-efficient EC motors with an external rotor and a centrifugal impeller with backward curved blades.
  • These state-of-the-art motors are the most advanced solution in energy efficiency today.
  • EC motors are characterised with high performance and optimum control across the entire speed range.
  • In addition to that, the efficiency of the electronically commutated motor reaches very impressive levels of up to 90 %.
HEAT EXCHANGER  
  • The VUT V(B) EC units are equipped with a counter-flow polystyrene heat exchanger.
  • In the cold season the extract air heat is captured and transferred to the supply air stream which reduces the ventilation-generated heat losses.
  • This can lead to formation of condensate that is collected in a special drain pan and discharged into the sewage system.
  • In the warm season the ambient air heat is transferred to the exhaust air stream.
  • This allows for a considerable reduction of the supply air temperature which, in turn, reduces the air conditioning load.

  • The VUE V(B) EC units are equipped with a counterflow enthalpy heat exchanger.
  • In the cold season the extract air heat and moisture are transferred to the supply air stream through the enthalpy heat exchanger reducing the heat losses from ventilation.
  • The ambient air heat and moisture are transferred to the exhaust air stream through the enthalpy heat exchanger in the warm season.
  • This allows for a considerable reduction of the supply air temperature and humidity which, in turn, reduces the air conditioning load.


CASING BYPASS
  • Made of high-quality polymer coated steel, internally filled with 20, 25, 30 or 40 mm (depending on the unit model) mineral wool layer for heat and sound insulation.
  • The VUT/VUE VB EC units are equipped with a bypass for summer ventilation (air cooling by the cool air from outside).
AUTOMATION  
  • The VUT/VUE V(B) EC A21 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).
  • The remote control panel is not included in the delivery set (available separately).
  • To control the unit via Wi-Fi, download the VENTS AHU 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.
  • The VUT 200 V(B) EC, VUT 250 V EC units are available only with the A14 automation system.

FREEZE PROTECTION  
  • Freeze protection is provided by the shutdown of the supply fan.
  • In the VUT/VUE VB EC A21 units it is possible to connect a preheater to protect the unit from freezing.
