Description

FEATURES

Efficient centralised ventilation unit for small apartments.
Can be installed vertically on the wall, or suspended under the ceilling.
Concealed installation is possble due to optional revision door.

Clean air due to the use of an ePM1 70% / F7 filter for supply air filtration.
Low noise operation from 13 dB(A) at 3 m.
Simple installation due to variable location of the spigots.

CASING

HEAT RECOVERY

The casing is made of galvanized sheet metal. The unit is heat- and sound-insulated with a 20 mm layer of foam. The service panel is easy to open for filter maintenance.

The Uni unit is equipped with a plate counter-flow polystyrene heat exchanger for heat recovery. The unit condensate is collected and drained to the drain pan under the heat exchanger. The Uni E unit is equipped with an enthalpy plate counter-flow heat exchanger for heat and humidity recovery.
The air flows are completely separated in the heat exchanger. Thus smells and contaminants are not transferred from the extract air to the supply air.
Heat recovery is based on heat and/or humidity transfer through the heat exchanger plates. In the cold season supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. Heat recovery minimizes ventilation heat losses and heating costs respectively. In the warm season the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cool extract air. That reduces operation load on air conditioners and saves electricity.

USP

The unit is equipped with four ø125 mm spigots. The position of the spigots can be changed to simplify duct installation.
Flanges can be installed in three different directions providing wide range of installation options.

CONTROL AND AUTOMATION

The Uni А21 units are equipped with an integrated automation system. The remote control panel is not included in the delivery set (sold separately).
The А21 controller allows integrating the unit into the Smart Home system or BMS (Building Management System). Unit control via Wi-Fi using the mobile application Vents AHU.
The Uni А14 units are equipped with an integrated automation system and the А14 wall mounted sensor control panel with LED-indication.

FANS

The units feature high-performance, electronically commutated (EC) external rotor motors with forward curved blades. These state-of-the-art units offer excellent energy efficiency. In addition to that, EC motors combine high performance and optimum control over the entire speed range. EC motors have an excellent power efficiency (up to 90 %).
