VENTS VUTR VE EC air handling units with heat recovery

• The VUTR VE EC air handling units are the fully-featured ventilation units that ensure air filtration, fresh air supply and stale air extraction.
• During the operation process the extract air heat is transferred to the intake air through the rotary heat exchanger.
• Used in ventilation and air conditioning systems in commercial, office and other public or industrial premises that require an economical solution and a controlled ventilation system.

• EC motors reduce energy demand by 1.5-3 times and ensure high performance and low noise operation.
• All models are designed for connection to ø125, 160 and 250 mm round air ducts.

• VUTR VE EC models are equipped with an electric heater.

• Made of galvanized steel, internally filled with a mineral wool heat- and sound-insulating layer.

• The insulation thickness is 20 mm for the VUTR 200 V2E EC models and 40 mm for the VUTR 280, 400 and 600 VE EC models.

• All units are equipped with a 5th spigot for connection of a kitchen hood (see the «Application options» section).
• The distinctive feature of the VUTR 200 V2E EC unit is the ability to connect a KH-1 kitchen hood (available upon separate order) directly to the unit.

• The two integrated G4 and F7 filters ensure sufficient intake air purification.
• Extract air is cleaned by the integrated G4 filter.

• The units are equipped with high-efficient EC motors with an external rotor and a centrifugal impeller.
• These state-of-the-art motors offer the very best in energy efficiency today.

• In addition to that, EC motors combine high performance and optimum control over the entire speed range.
• The high efficiency (up to 90 %) is a definite advantage of EC motors.

Rotary heat exchanger operation principle

• The rotary heat exchanger is a short rotating cylinder filled with layers of corrugated aluminium tape packaged in a such way so as to enable free passage of the supply and extract air flows.
• As the cylinder rotates the aluminium tape contained in the heat exchanger is first exposed to the supply air stream and then to the extract air stream.
• As a result the material undergoes repeated warming and heating cycles thereby transferring heat and humidity from the warm air stream to the cold one.
• As compared to plate heat exchangers, the rotary heat exchangers are distinguished with no condensate forming, ability to maintain comfortable air humidity and extremely low freezing danger.

• The VUTR V(2)E EC units are equipped with an electric heater.
• If heat recovery is not sufficient to reach the set supply air temperature, the heater is activated to warm up supply air.

• The heaters are equipped with protecting devices to ensure safe and reliable operation of the unit.

• The VUTR V(2)E EC 21 units are equipped with an integrated control system.
• The A21 controller allows integrating the unit into the Smart Home system or BMS (Building Management Systems).
• The remote control panel is not included in the delivery set (purchased separately).
• To control the unit using a mobile application via Wi-Fi, you need to download the VENTS AHU mobile application.
