    Description
    Description
    DESCRIPTION
    • The VUT PB EC air handling units are the fully-featured ventilation units that ensure air filtration, fresh air supply and stale air extract.
    CASING
    • Made of galvanised steel, internally filled with a 40 mm heat- and sound-insulating layer of mineral wool.
    FILTER
    • Built-in panel filters with filtration class F7 provide efficient supply air filtration.
    • Panel filters with filtration class G4 provide extract air filtration.

    FANS
    • High-efficient electronically-commutated motors with an external rotor and backward curved blades.
    HEAT EXCHANGER
    • The units are equipped with a high-efficient 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.

    FREEZE PROTECTION
    • To protect the heat exchanger from freezing in the cold season, the unit has a Frost Protection mode based on the temperature sensor readings.
    • The Frost Protection mode is activated at an exhaust air temperature of +3 ˚C.
    • After temperature increase the unit returns to the previous operation mode.
    • In case of freezing danger, the supply fan is turned off in VUT 160/250/350 PB EC A14 units.
    • Three modes of freeze protection are available in VUT 160/250/350 PB EC A21 models:
      • gradual reduction of the supply fan speed
      • with the bypass
      • with the electric preheater (available as an accessory).
    BYPASS
    • The units are equipped with a 100 % bypass which can be opened for summer cooling.
    MOUNTING
    • The units are designed for ceiling or wall mounting (horizontal spigot orientation) in a position allowing condensate collection and removal into a special drain pan.
    • The access for filter maintenance and replacement is available from the bottom panel.
    		 AUTOMATION
    • The VUT PB EC A21 units are equipped with an integrated automation system.
    • The A21 controller enables integration of 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 PB EC A14 units are equipped with an integrated automation system and a wall-mounted control panel A14 with LED indication.
