Description

DESCRIPTION

The air-handling units are the fully featured ventilation units with heat recovery for air filtration, fresh air supply and stale air extraction.

CASING

Made of high-quality polymer coated steel, internally filled with mineral wool layer for heat and sound insulation.

FILTER

Supply and exhaust air flows are purified through panel filters with filtering class G4 and F7, respectively.
Filters with G4 filtering class are used for supply and exhaust air purification in the VUT/VUE 250 VB EC units.
F7 filter is available as an option for supply air filtration.

FANS

The units are equipped with high-efficient EC motors with an external rotor and a centrifugal impeller with backward curved blades.

HEAT EXCHANGER

The VUT V(B) EC units are equipped with a counter-flow polystyrene heat exchanger.

The VUE V(B) EC units are equipped with a counter-flow enthalpy heat exchanger.

BYAPASS

The VUT/VUE VB EC units are equipped with a bypass for summer сooling.

FREEZE PROTECTION

In the VUT/VUE 160/350/550 VB EC A21 units it is possible to connect a preheater to protect the unit from freezing.
The VUT 250 VB EC A21 unit is equipped with a built-in preheater for frost protection.

MOUNTING

The units are designed for wall or floor mounting.
Access for maintenance of units and filters is possible from the right and left sides.

AUTOMATION

The VUT/VUE V(B) EC A21 units 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).
To control the unit via Wi-Fi, download the VENTS Home 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.

Calculation of air temperature downstream of the heat exchanger:

t = t_outd + k_hr * (t_extr - t_outd) / 100,

where
t_outd - outdoor air temperature [°C]
t_extr - extract air temperature [°C]
k_hr - heat exchanger efficiency (according to the diagram) [%]
