APPLICATION

Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.Heat recovery minimises ventilation heat losses.Control of air exchange for creating comfortable indoor microclimate.Compatible with round Ø125 to 315 mm air ducts.

DESIGN

The casing is made of aluminium profile and double-skinned aluzinc panels, internally filled with mineral wool layer for heat and sound insulation.The casing has fixing brackets with vibration absorbing connectors for easy installation.The spigots for connection to the air ducts are located at the side of the unit and are rubber sealed for airtight connection to the air ducts.The hinged casing side panels ensure easy access to the internals for cleaning, filter replacement and other maintenance operations.

FANS

Asynchronous external rotor motors and centrifugal double-intake impellers with forward curved blades are used for air supply and exhaust.Integrated motor overheating protection with automatic restart.Dynamically balanced impellers.Equipped with ball bearings for longer service life.Reliable and quiet operation.

AIR FILTRATION

Two built-in G4 cassette filters provide efficient supply and extract air filtration. Optionally, an F7 supply filter may be used (special accessory).

HEAT RECOVERY

The unit is equipped with a cross-flow aluminium heat exchanger with a large surface area and high heat recovery efficiency.The air flows are fully separated within the heat exchanger. Odours and contaminants contained in the extract air are not transferred to the supply air flow.Heat recovery is based on the utilization of the thermal energy of the extract air for heating up supply air. Extract air transfers most of its heat to the intake air flow. Heat recovery reduces heat losses in cold seasons. In summer the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cool extract air.This contributes to better performance of the air conditioner in ventilated premises.The built-in freezing protection system automatically turns the supply fan off in case of a freezing danger to enable warming of the heat exchanger with the warm extract air flow. When a freezing danger is over the the supply fan is turned on and the unit reverts to previous operation mode.The drain pan under the heat exchanger block is used for condensate collection and drainage.Heat recovery is not useful in warm season with small indoor and outdoor temperature difference. In this case the heat exchanger may be temporary replaced with a summer block (available separately).

CONTROL AND AUTOMATION

Speed control by means of the four-position speed switch CDP-3/5 that enables setting low, medium, maximum speed and turning the unit off.

MOUNTING

Mounting to floor, ceiling or wall with fixing brackets.The correct mounted unit must provide condensate collecting and drainage and free access to the hinged side panel for servicing and filter replacement.
