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.
