VENTS VUTR 250 P2E EC

• The air handling units VUTR P/PE 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 ø160 and 200 mm round air ducts.

• VUTR P(2) EC models (without an electric heater).
• VUTR P(2)E EC models (with an electric heater).

• VUTR P2(E) EC models with a low profile casing and 20 mm insulation.

• Made of galvanized steel, internally filled with a mineral wool heat- and sound-insulating layer.
• The insulation thickness is 40 mm for the VUTR P/PE EC models and 20 mm for the VUTR P2/P2E EC models.
• Unit maintenance is performed from the bottom panel side.
• The distinctive feature of the VUTR P2/P2E EC units is a low profile casing.

• Two built-in filters with filtering class G4 and F7 provide efficient supply air filtration.
• Extract air is cleaned by the integrated G4 filter.
• The optional H13 filter is available for supply air filtration.

• 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.

• EC motors are characterised with high performance and optimum control across the entire speed range.
• In addition to that, the efficiency of the electronically commutated motor reaches very impressive levels of up to 90 %.

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 PE 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 P/P2/PE/P2E EC A17 units are equipped with the th-Tune control panel with an LCD display.

• The VUTR P/P2/PE/P2E 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.
• Unit operation mode selection: Automatic mode, Ventilation mode (can be enabled only from the pGD1 control panel).
• Maintaining a pre-set room temperature by switching the rotary heat exchanger on and off.
• 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 pre-programmed 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 ceiling, wall or floor mounting on a horizontal surface.
