Description
Description
DESCRIPTION  
  • 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.
MODIFICATIONS  
  • 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.
CASING
  • 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.
FILTER
  • 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.
MOTOR  
  • 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

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.
HEATER  
  • 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.
AUTOMATION  
  • 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.
AUTOMATION FUNCTIONS  
  • 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.
INSTALLATION  
  • The unit is designed for ceiling, wall or floor mounting on a horizontal surface.

Calculation of air temperature at heat exchanger outlet:

t = tint + keff * (text - tint) / 100,

Where
tint - intake air temperature [°С],
text - extract air temperature [°С],
keff - heat recovery efficiency (as per diagram) [%]
