VENTS VUT/VUE 180 P5B EC air handling units with heat recovery

• The air handling units are the fully featured ventilation units with heat recovery for air filtration, fresh air supply and stale air extract.
• The extract air heat is used for warming up of the supply air stream in the high-efficient plate heat exchanger.

• The units offer energy-efficient ventilation for cottages and flats and are compatible with round Ø 150 mm air ducts.

• Two built-in G4 and F7 filters provide efficient supply air filtration.
• The G4 filter is used for extract air filtration.

• The casing is made of expanded polypropylene (EPP) possessing high heat- and sound-insulating properties.

• The VUT/VUE 180 P5B EC A14/A21 units are equipped with a bypass for summer ventilation (cooling of the premise with cool outside air).

• High-efficient electronically commutated motors with external motor and impeller with forward 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.

• The VUT 180 P5B EC units are equipped with a counter-flow polystyrene heat exchanger.
• In the cold season the extract air heat is transferred to the intake air stream which reduces 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 outside air heat is transferred to the exhaust air stream.
• This allows for a considerable reduction of the supply air temperature which, in its turn, reduces the air conditioning load.

• The VUE 180 P5B EC units are equipped with a counter-flow heat exchanger with an enthalpy at the core.
• In the cold season the extract air heat and moisture are transferred to the supply air stream through the enthalpy.
• Heat recovery minimises heat losses from ventilation.
• In the warm season the outdoor air heat and moisture are transferred to the exhaust air stream through the enthalpy heat exchanger.
• This enables considerable reduction of the supply air temperature and humidity which, in its turn, reduces the load on air conditioners.

• The VUT/VUE 180 P5B EC A21 units are equipped with integrated control system.
• The A21 controller allows integrating the unit into the Smart Home system or BMS (Building Management Systems).
• Remote control panel is not included in the delivery set and is available as specially ordered accessory.
• The unit is controlled via Wi-Fi by means of the VENTS AHU mobile application that must be downloaded.
• The VUT/VUE 180 P5B EC A14 units are equipped with integrated control system and the A14 wall-mounted control panel with LED indication.

• For VUT/VUE 180 P5B EC A14 the freeze protection is realized by means of shutdown the supply fan.

• For VUT/VUE 180 P5B EC A21 the freeze protection is realized by means of turning the preheater on.
