VENTS VUT/VUE VB EC A11 air handling units with heat recovery

• 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).

• Supply and exhaust air flows are purified through panel filters with filtering class G4 and F7, respectively.
• Supply airflows in the VUT/VUE 250 VB EC units are purified through G4 and F7 filters.
• Exhaust airflows are purified through G4 filters.

• The units are equipped with high-efficient EC motors with an external rotor with backward curved blades.
• These state-of-the-art motors offer the very best in energy efficiency today.
• The high efficiency (up to 90 %) is a definite advantage of EC motors.

• The VUT VB 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 VB 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 membrane reducing the heat losses from ventilation.
• The ambient air heat and moisture are transferred to the exhaust air stream through the enthalpy membrane 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.

• Made of high-quality polymer coated steel, internally filled with 20, 30 or 40 mm (depending on the unit model) mineral wool layer for heat and sound insulation.

• The VUT VB EC and VUE VB EC models are equipped with a bypass which can be opened if there is a need to cool down the ventilated area with cool intake air without heat recovery.

• The VUT/VUE VB EC A11 units have the LCD sensor control panel PU SENS 01.

• Two ways of freeze protection are available: 

• Supply fan stopping.
• Preheating: when the outdoor air temperature drops below -3 °C, the heat exchanger freeze protection algorithm is activated by the NKP electric heater that heats the intake air.

• The heater power is continuously adjusted by the automation system in order to prevent condensate freezing in the heat exchanger. 

• The units are designed for wall or floor mounting.
• The access for unit and filter maintenance is available from the front panel.

• During mounting stage the front and the back panels can be reversed providing either left-handed or right-handed unit mounting.

* The unit design differs depending on the model
