Description

DESCRIPTION

CASING

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

The casing is made of 15-26 mm thick expanded polypropylene (EPP), possessing high heat- and sound-insulating properties.

FILTER

FANS

Supply and extract air flows are purified through G4 panel filters.
For extra supply air filtration a F8 filter is available as a specially ordered accessory.

High-efficient electronically commutated motors with external motor and impeller with backward curved blades.

HEAT EXCHANGER

The VUT 270 V5B EC units are equipped with a counter- flow polystyrene heat exchanger.

The VUE 270 V5B EC units are equipped with an enthalpy counter-flow heat exchanger.

BYPASS

AUTOMATION

The VUT/VUE 270 V5B EC units are equipped with a bypass for summer ventilation (cooling of the premise with a cool outside air).

FREEZE PROTECTION

For VUT/VUE 270 V5B EC A14 the freeze protection is realized by means of shutdown the supply fan.
For VUT/VUE 270 V5B EC A21 the freeze protection is realized by means of turning the preheater (available as an accessory) on.

INSTALLATION

The units are designed for wall and floor mounting.
The access for unit and filter maintenance is available on the right and left side.

The VUT/VUE 270 V5B EC A21 units are equipped with control system.
The A21 controller allows integrating the unit into the Smart Home system or BMS (Building Management Systems).
The unit is controlled via Wi-Fi by means of the VENTS Home mobile application that must be downloaded.

The VUT/VUE 270 V5B EC A14 units are equipped with integrated control system and wall-mounted sensor control panel A14 with LED indication.

Calculation of air temperature at heat exchanger outlet:

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

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