FEATURES

Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings. Heat recovery minimises ventilation heat losses. Controllable air exchange for creating the best suitable indoor microclimate. Compatible with round Ø 125 mm air ducts.

DESIGN

The compact casing is made of double-skinned aluzinc panels, internally filled with 15 mm PE foam film layer for heat and sound insulation. The casing has mounting angles 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 supply and exhaust spigots are equipped with backdraft dampers. The hinged side panel of the casing ensures easy access to the internals for cleaning and other maintenance operations.

FANS

Asynchronous motors are used for air supply and exhaust. Centrifugal impeller with forward curved blades ensures high pressure and low noise level. Integrated overheating protection. Dynamically balanced impellers. Equipped with ball bearings for longer service life.

HEAT RECOVERY

The KOMFORT Ultra D 105-A unit is equipped with a plate cross-flow polystyrene heat exchanger for heat recovery. The unit condensate is collected and drained to the drain pan under the heat exchanger. The KOMFORT Ultra D 105 unit is equipped with an enthalpy plate cross-flow heat exchanger for energy (heat and humidity) recovery. Due to humidity recovery condensate is not generated in the enthalpy heat exchanger. The air flows are completely separated in the heat exchanger. Thus smells and contaminants are not transferred from the extract air to the supply air. Heat recovery is based on heat and/or humidity transfer through the heat exchanger plates. In the cold season supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. Heat recovery minimizes ventilation heat losses and heating costs respectively. In the warm season the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cool extract air. That reduces operation load on air conditioners and saves electricity. When the indoor and outdoor temperature difference is insignificant, heat recovery is not reasonable. In this case the heat exchanger can be temporary replaced with a summer block for the warm season (available as a specially ordered accessory).

FROST PROTECTION

The integrated electronic frost protection system in KOMFORT Ultra D 105-A is used to prevent the heat exchanger freezing in cold seasons. In case of heat exchanger freezing danger communicated by the temperature sensor the supply fan is stopped to let warm extract air warm up the heat exchanger. After that the the supply fan is turned on and the unit reverts to the normal operation mode.

AIR FILTRATION

The built-in G4 supply filter and G4 extract filter provide air filtration.

CONTROL AND AUTOMATION

The unit has three speeds. Air flow control by the external speed switch CDP-3/5.

MOUNTING

Indoor installation in horizontal position. Mounting in a false ceiling is possible due to compact casing size. A small air distribution network for central ventilation may be arranged based on the unit. The correct mounted unit must provide free access to the hinged side panel for servicing and filter replacement.
