Heat recovery air handling units VENTS VUE P3 A3/A4

Description

APPLICATION

The VUE P3 A3/A4 air handling units are the fully-featured ventilation units that ensure air filtration, fresh air supply and stale air extract.
During the operation process the extract air heat is transferred to the supply air through the plate heat exchanger.

The units are used in ventilation systems installed in various premises that require reasonable energy saving solutions and controllable ventilation systems.
All models are designed for connection to ø100 and 150 mm round air ducts.

FANS

DESIGN

The single-phase three-speed motors with an external rotor and an impeller with forward curved blades.
The motors have an integrated overheating protection with an automatic restart.

The casing is made of polymer-coated steel panels, internally filled with polyurethane foam layer of 5 or 10 mm for heat- and sound-insulation.

HEAT RECOVERY

The plate enthalpy cross-flow heat exchanger with heat recovery efficiency up to 87 %.
The applied heat exchanger enables not only heat but also humidity recovery, which helps maintaining an optimum humidity level.
In warm seasons the heat exchanger operates to cool down and dehumidify the supply air. In cold seasons the heat exchanger operates to warm up supply air and to humidify it
The recovered humidity and heat are transferred to the supply air flow.
The air streams are fully separated within the heat exchanger and the microbes and smells are isolated.

FILTER

CONTROL AND AUTOMATION

Two integrated panel filters with filtering class G4 and F8 provide efficient supply air filtration.
Extract air is cleaned by an integrated G4 filter.

The unit is equipped with an integrated control system, a mechanical three-speed speed controller P3-1-300 or a sensor three-speed speed controller SP3-1, and a power cable with a mains plug.


P3-1-300	SP3-1

The service side of the unit is equipped with a removable hatch for filter and heat exchanger cleaning and replacement operations.
The control unit is positioned inside the unit casing.
The power cable and grounding cables are connected to the control unit via the cable glands placed at the side of the unit.

FREEZE PROTECTION

INSTALLATION

The heat exchanger freeze protection operates as follows: in case of freezing danger determined by the temperature sensor, the supply fan is turned off to let extract air warm up the heat exchanger.

Due to a low casing height the air handling units are a perfect solution for space-restricted installation above suspended ceilings.
The unit mounting position must provide access for service maintenance.
