DESCRIPTION |
|
- 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.
|
FILTER |
 |
- Two built-in G4 and F7 filters provide efficient supply air filtration.
- The G4 filter is used for extract air filtration.
|
CASING |
BYPASS |
- 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).
|
FANS |
|
- 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.
|
HEAT EXCHANGER |
|
- 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.

|
AUTOMATION |
|
- 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.
|
|
FREEZE PROTECTION |
|
- 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.
