  • The air handling units VUTR EH EC with an electric heater 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 and air conditioning 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. 

  • The VUTR 400/700/900/1200/1500 EH EC units are compatible with round air ducts (Ø 160, 250 and 315 mm).

  • The VUTR 2000 EH EC units are compatible with rectangular air ducts (Ø 500x300).

  • The casing consists of a frame and three-layer 20 mm (VUTR 1500 and 2000 – 25 mm) thick panels made of zinc aluminium internally filled with mineral wool for reliable heat- and sound-insulation.

  • Due to the specially designed removable side panels the unit requires little space for servicing and accessing to all the unit components.

  • The two integrated G4 filters ensure sufficient supply and extract air purification.

  • The air handling units are equipped with high-efficiency electronically commutated (EC) direct current motors with an external rotor and backward-curved blades.

  • 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.

  • 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.

  • Compared to plate-type devices a rotary heat exchanger demonstrates better efficiency and helps maintain a comfortable air humidity level while reducing frostbite danger to a bare minimum (tending to zero at normal temperature and humidity).

  • The air handling units are equipped with electric heaters to operate at low outside temperatures.

  • 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 EH EC A17 units are equipped with a th-Tune control panel.

  • The VUTR EH EC A18 units are equipped with a pGD1 control panel.
  • Speed selection: low, medium, high.
  • Speed is individually adjusted from 0 to 100 % for the supply and the extract fans.
  • Filter maintenance indication.
  • Alarm indication.
  • Timer-based operation.
  • Week-scheduled operation.
  • Supply air temperature control.
  • CCU control.
  • Air damper actuator controlling.
  • The unit is designed for mounting to a horizontal plane, suspension to a ceiling or wall mounting by means of brackets.
  • Service access is from the left side panel (in air direction).

t = toutd + khr * (text - toutd) / 100, 


toutd – outdoor air temperature [°C],

text – extract air temperature [°C],

khr – heat exchanger efficiency
