The AVU series air handling units represent a new fully-featured ventilation solution in the AirVents unit series. Due to the compact modular design the unit may be modified and supplemented by various functional sections on customer’s demand specific to the design documentation. The AVU series air handling units are applied for construction objects of any complexity.

As of today VENTS offers you the AVU 03 model with air capacity up to 3 000 m³/h. The AVU air handling unit series is expected to be supplemented with AVU 05, AVU 07, AVU 09, AVU 11 and AVU 14 models with air capacity 5 000, 7 000, 9 000, 11 000 and 14 000 m³/h respectively.

The AVU 03 air handling unit is a fully-featured ventilation unit that ensures air filtration, fresh air supply and stale air extraction. Extract air heat energy is recovered and transferred to supply air flow with a rotary regenerator with heat recovery efficiency up to 65%.

As compared to plate heat exchangers, advantages of the rotary regenerator include the ability to maintain comfortable indoor air humidity and extremely low freezing danger of the regenerator.

The AVU 03 air handling units are designed for inner and outer mounting.

The inner mounting models (AVU 03/SE/R) have an aluzinc casing with the wall thickness 25 mm. and the outer mounting models (AVU 03/SE/R/О) have an aluzinc casing with the wall thickness 50 mm.

The AVU 03 unit casing is made of aluzinc sandwich panels, internally filled with mineral wool layer for reliable heat- and sound-insulation.

Specially designed swivel side panels of the unit ensure easy access to the unit components and enable the unit mounting in limited maintenance space conditions. The supply and exhaust air ducts are fitted with electrically actuated air dampers. The outer models are equipped with protecting hoods for fresh air intake and stale air exhaust.

The AVU 03 units are equipped with high-efficient electronically-commutated direct current motors with external motor and impeller with backward curved blades. Such motors are the most state-of-the-art energy-saving solution. EC motors are featured with high performance and total speed controllable range. High efficiency reaching 90% is the premium advantage of the electronically commutated motors. The integrated EC motors in the AVU 03 unit let decrease energy demand by 1.5-3 times and provide high performance and low energy demand.

The AVU 03 unit is equipped with two supply air filters, one of G4 panel type and the other of F7 bag type. The extract is purified through the G4 panel type filter.

The unit AVU 03 may be equipped with a water heater for the unit operating conditions at low outside temperatures (model AVU 03/…H). If set supply air temperature may not be attained with heat recovery only, the heater is turned on and warms up supply air flow.

The unit has connection possibilities for a water cooling block (C3 / AVU 03, special accessory) or DX cooling block (DX3 / AVU 03, special accessory) to enable extra cooling of supply air. These blocks are available in outer and inner modifications with a panel width 50 or 25 mm respectively.

The AVU 03 unit has an integrated automation control system that enables the unit turning on/off, setting supply air temperature and unit air capacity from the remote control panel, actuating air dampers, controlling filter clogging degree, supply air controlling and regulating by actuating the heat medium regulating three-way valve, circulation pump controlling and regulating. The water heater freezing protection is carried out by the temperature sensor downstream of the water heater and the return heat medium thermostat.
