Description

DESCRIPTION

The intelligent arrangement of fans, heat recovery cores and filters, makes units slimline and easy to mount in small loft spaces, ceiling voids and false ceilings.

Such as electric & LPHW heaters, volume control dampers and Nox filters are available.

CASING

Casing panels made of zinc–aluminum coated steel with a 40 mm mineral wool heat- and sound-insulating layer.
Corrosion class C4 according to ISO 12944: class C4.

Each model available in left or right versions.
Service access on both sides and bottom.
Units are designed for indoor installation.

FILTER

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.

FANS

Fans with ERP-compliant EC motors.
Impellers with backward-curved blades.

Low power consumption at any speed, low noise and stable operation in any climate.

HEAT EXCHANGER

High-efficient counter-flow heat exchanger made of polystyrene.
Stainless steel drain pan on both supply and exhaust sides.

BYPASS

Automatic heat exchanger bypass damper with Belimo actuator provides active frost protection, free-heating and freecooling functions.

CONTROL AND AUTOMATION

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.
