  • Accessories
  • The air handling units VUTR 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 P2E EC models (with an electric heater).
  • VUTR P2E 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 PE EC models and 20 mm for the VUTR P2E EC models.
  • Unit maintenance is performed from the bottom panel side.
  • The distinctive feature of the VUTR 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 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 PE/P2E EC A21 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.
