The Vents VUT 300 G mini air handling unit is designed for ventilation of one to three rooms in residential or commercial premises. This model is capable of supplying fresh air with a nominal capacity of300 m3/h. The maximum consumption of the installation is only116 Wper hour, since the heating installation does not use a heater. Installation of the unit must be carried out in a closed room with a positive temperature. The ventilation unit is connected to125 mm air ducts. This model is mountedunder the ceiling or on the wall in a horizontal position.

Casing

The casing is made of aluminum-zinc steel, with internal heat and sound insulation 20 mm thick made of mineral wool.

Filter

To filter supply and exhaust air, the unit has two built-in filters with a cleaning degree of G4.

Fans

The Vents VUT 300 V mini unit is equipped with supply and exhaust centrifugal fans with backward-curved blades and a built-in protection thermostat with automatic restart. Electric motors and impellers are dynamically balanced in two planes.

Recuperator

The plate recuperator is made of aluminum plates. For operation of the unit without recuperation, a “summer” liner is provided. Under the recuperator block there is a tray for collecting and discharging condensate. The supply and exhaust unit is equipped with a built-in system for protecting the recuperator from freezing.

During the operation of the recuperator in the cold season, heat is transferred from the warm exhaust air to the cold supply air. In this case, condensation may form in the recuperator during the cooling of the exhaust air, and when the temperature of the supply air entering the recuperator on the other side is on average below -5°C, the condensate in the exhaust ducts may freeze.

To avoid the process of freezing of the recuperator Electronic frost protection is used. Its essence is that the temperature sensor turns off the supply fan. Warm exhaust air warms up the recuperator. Then the supply fan is turned on, and the entire installation operates in normal mode.

Control

The installation is turned on and its performance is controlled using a thyristor engine speed controller (RS-1-400), which allows you to smoothly change the fan rotation speed in the range of 0–100%.

Installation

The air handling unit is mounted on the floor, suspended from the ceiling using a mounting bracket with a vibration insert, or mounted on the wall with using brackets. The installation can be placed both in auxiliary rooms and in the main ones (behind a suspended ceiling, in a niche or in an open way). It can only be installed in such a position as to ensure collection and drainage of condensate. Access for service and filter cleaning is from the folding side panel.
