Vents VUT PE EC 350 – 3000

Categories: ,

Ceiling mounted air handling units in compact heat and sound-insulated casing with electic heater. Air capacity up to 4000 m3/h, heat recovery efficiency up to 90%.


The VUT PE EC air handling unit with electric heater and the VUT PW EC air handling unit with water 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 capacity 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.
VUT PW EC – models with water heater.


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

Heat exchanger

VUT 350, 600, 1000 PE/PW EC models are fitted with a counter-flow heat exchanger made of polystyrene. VUT 2000, 3000 PE/PW 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) or the water heater (for the unit VUT PW) 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 water heaters are designed for max. operating pressure 1.0 MPa (10 bar) and max. heat medium operating temperature +95 °C.

Control and automation

The unit includes an integrated automation and a multifunctional control panel with a remote LCD control panel.

  • The VUT PE/PW EC unit incorporates a LCD control panel with a colour sensor display PU SENS 01.
  • The VUT PE/PW EC A7 unit incorporates a monochrome LCD display PU JK 01. The PU SENS 01 and PU JK 01 are interchangeable.

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.
