    Description
    Description
    DESCRIPTION
    • The VUT/VUE HB EC and VUT/VUE HBE EC air handling units are the fully-featured ventilation units that ensure air filtration, fresh air supply and stale air extract.
    • Used in ventilation and air conditioning systems in commercial, office and other public or industrial premises that require an economical solution and a controlled ventilation system.
    CASING
    • Made of aluzinc steel, internally filled with a 40 mm mineral wool heat- and sound-insulating layer.
    FILTER
    • Two built-in panel filters with filtration class G4 and F7 provide efficient supply air filtration.
    • The G4 panel filter is used for extract air cleaning.

    FANS
    • High-efficient electronically-commutated motors with external rotor.
    • The 700 size units are equipped with fans with backward curved blades.
    HEAT EXCHANGER
    • The VUT units are equipped with a counter-flow polystyrene heat exchanger.

    • The VUE units are equipped with enthalpy counter-flow heat exchanger.

    HEATER
    • The VUT/VUE HBE EC units are equipped with an electric heater for additional heating of supply air downstream of the heat exchanger.
    BYPASS
    • The unit is equipped for summer cooling.
    • If the unit is equipped with an electric heater, the bypass is used for freeze protection of the heat exchanger.
    FREEZE PROTECTION
    • Freeze protection in the VUT/VUE HBE EC A21 units is achieved by a bypass.
    • A preheater can be additionally installed in the VUT/VUE HB EC A21 units for freeze protection.
    MOUNTING
    • The unit is designed for suspended or floor mounting.
    • Access for service and filter cleaning 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.
    		 MODIFICATIONS
    • The VUT HB EC model is equipped with a counter-flow heat exchanger made of polystyrene.
    • The VUT HBE EC model is equipped with a counter-flow heat exchanger made of polystyrene and an electric heater.
    • The VUE HB EC model is equipped with with an enthalpy counter-flow heat exchanger.
    • The VUE HBE EC model is equipped with an enthalpy counter-flow heat exchanger and an electric heater.
    AUTOMATION
    • The VUT/VUE HB(E) EC A21 units are equipped with an integrated control system.
    • The A21 controller allows integrating the unit into the Smart Home system or BMS (Building Management Systems).
    • To control the unit using a mobile application via Wi-Fi, you need to download the VENTS Home mobile application.
