VENTS VUT PBE EC, VUT PBW EC air handling units with heat recovery

• The VUT PBE EC air handling unit with an electric heater and the VUT PBW EC air handling unit with a water heater are the fully-featured ventilation units ensuring 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, 200, 250 mm air ducts.

• VUT PBE EC – models with the electric heater.
• VUT PBW EC – models with the liquid (water, glycol) heater.

• The heat- and sound-insulated aluzinc casing is internally filled with 20 mm mineral wool for VUT 300, 550 and 900 PBE/PBW EC units.

• Supply and extract air flows are purified through two panel filters of the filtering class G4.
• The supply filter of the filtering class F7 can be provided optionally.

• 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.

• Models are fitted with a counter-flow plate heat exchanger made of polystyrene.
• In the cold season the extract air heat is captured and transferred to the supply air stream which reduces the ventilation-generated heat losses.
• This can lead to formation of condensate that is collected in a special drain pan and discharged into the sewage system.
• In the warm season the ambient air heat is transferred to the exhaust air stream.
• This allows for a considerable reduction of the supply air temperature which, in turn, reduces the air conditioning load.

• The units are equipped with a bypass for summer ventilation (cooling of the premise with cool outside air) and freeze protection of the heat exchanger.

• The units are equipped with an integrated automation system.
• The A21 controller enables integration of 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 via Wi-Fi, download the VENTS AHU mobile app.

• The electric heater (for the unit VUT PBE EC) or the water heater (for the unit VUT PBW EC), installed after 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.

• The unit is designed for indoor mounting.
• While mounting the unit ensure its correct position to enable condensate collection and drainage.
