VENTS VUTR V EC, VENTS VUTR VE EC air handling units with heat recovery

• The air handling units VUTR V/VE EC are the fully-featured ventilation units that ensure air filtration, fresh air supply and stale air extract.
• During the operation process the extract air heat is transferred to the supply air through the rotary heat exchanger.
• The units are used in ventilation systems installed in various premises that require reasonable energy saving solutions and controllable ventilation systems.

• 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 V EC models without a heater.

• 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 V2/V2E EC models and 40 mm for the VUTR 280, 400 and 600 V/VE EC models.

• All units are equipped with the 5th spigot for kitchen hood connection (see the «Application option» section).
• The distinctive feature of the VUTR 200 V2/V2E EC is the ability to connect the KH-1 kitchen hood (avail able upon separate order) directly to the unit.

• The two integrated G4 and F7 filters ensure sufficient supply air purification.
• Exhaust 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/VE EC A17 units are equipped with the th-Tune control panel with an LCD display.

• The VUTR V/VE EC A18 units are equipped with the pGD1 control panel with an LCD display.

• The th-Tune and pGD1 control panels are interchangeable.
• The standard delivery set includes a 10 m cable for connection to the control panel.

• Turning the unit on/off.
• Enabling unit operation modes: Automatic mode, Ventilation mode (can be enabled only from the pGD1 control panel).
• Maintaining a pre-set room temperature by activating/deactivating the rotary heat exchanger.
• Automatic reduction of the supply and exhaust ventilation air flow rate to obtain the user-defined minimum allowable supply air temperature.
• Supply and exhaust fan control.

• Unit operation according to a preprogrammed schedule.
• Controlling the electric actuators of the supply and exhaust air dampers.
• System shutdown on signal from fire fighting system.
• When connecting external electrical heating elements and/or CCU to the unit the activation signal controls their operation if cooling/heating is required.
• Filter contamination control by the number of operating hours.

• The unit is designed for wall or floor mounting.
• The access for unit and filter maintenance is available from the front panel.

• The service and the back panels can be rearranged allowing connection both on the right and on the left side.
