  • The VUT PE EC air handling units with the electric heater are the fully-featured ventilation units ensure air filtration, fresh air supply and stale air extract.

  • The heat energy contained in extract air is transferred to supply air through the plate heat exchanger.

  • The units are suitable for integration into various ventilation and air conditioning networks requiring cost-effective solutions and controllable ventilation.

  • The integrated EC motors reduce energy demand by half up to three-fold and provide high air flow and low noise level.

  • All the models are compatible with round 160 (150), 200, 250, 315 and 400 mm air ducts.

  • VUT PE EC – models with the electric heater.

  • The aluzinc casing is internally filled with 20 mm mineral wool for VUT 350, 600, 1000 PE EC and 25 mm for VUT 2000, 3000 PE EC units.

  • Supply and extract air flows are purified through two panel filters with filtering class G4. 

  • Supply filter F7 can be supplied with the few models.
  • High-efficient electronically-commutated motors with external motor and impellers with backward curved blades.

  • Such motors are the most state-of-the-art energy-saving solution.

  • EC motors are featured with high performance and total speed controllable range.

  • High efficiency reaching 90% is the premium advantage of the electronically-commutated motors.

  • VUT 350, 600 and 1000 PE EC models are fitted with a counter-flow heat exchanger made of aluminum. VUT 2000 and 3000 PE EC models are fitted with a cross-flow plate heat exchanger made of aluminum.

  • All the units are equipped with a drain pan for condensate drainage.

  • The electric heater (for the unit VUT PE) the heat exchanger is designed for warming up of supply air up to the set level if heat recovery is not enough to attain the set supply air temperature.

  • The unit includes an integrated automation and a multifunctional control panel with a remote LCD control panel.
  • The delivery set includes a 10 m connecting cable for connection of the unit to the control panel.
  • The freezing protection function is performed by means of the bypass and the heater.
  • In case of a freezing danger according to the temperature sensor readings the bypass damper is opened to let supply air flow through the bypass duct and not come in contact with the heat exchanger.
  • The heater warms up supply air up to the required temperature and meanwhile the heat exchanger is heated by the warm extract air.
  • After the heat exchanger defrosting the bypass damper closes the bypass duct and the air handling unit reverts to the standard operation mode.

The VUT PE EC unit incorporates a LCD control panel

with a colour sensor display PU SENS 01.


Control panel:

  • Turning air handling unit on/off, room temperature indication, low-medium-high speed selection.
  • Opening/closing bypass for summer ventilation; timer mode activation, setting week scheduled operation (applicable only for PU SENS 01).
  • Supply and exhaust fan speed stage adjustment from 0 up to 100% during the system set-up.
  • Set indoor air maintaining by feedback of the sensor on the control panel.
  • Overheating protection for the electric heating elements according to feedback of the duct temperature sensor as well as signal from the two thermal switches, one of self-resetting type actuated at +60°C and the other one of manual reset type actuated at +90°C.
  • Cooling of the electric heating elements at the end of the heating cycle;
  • Actuating external air dampers.
  • Maintaining set indoor or room air temperature.
  • Control according to the duct humidity sensor feedback HV1 (special accessory) or according to the humidity sensor in the control panel.
  • Filter clogging control by filter timer.
  • Ventilation system shutdown at signal from the fire alarm system.
  • Cooler connection possibility.
  • The unit is designed for indoor mounting. While mounting the unit ensure its correct position to enable condensate collection and drainage.

  • Access for servicing and cleaning of the filter is from the right or left side panel for the dimension types 350, 600 and 1000 and from the bottom for the dimension types 2000 and 3000.
  • For attenuation of sound generated by the fans it is recommended to install the duct silencer (refer SR) from inside before the unit.

  • For absorbing of vibration in the air duct it is recommended to install the flexible anti-vibration connectors (refer VVG) on both sides of the unit.

  • To disable uncontrollable air backdrafting during the fan standby and to prevent the water heater freezing the units must be equipped with automatic air dampers.
