FEATURES
Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.Heat recovery minimizes ventilation heat losses during cold season and reduces air conditioner load during hot season.Controllable air exchange provides the best indoor microclimate.Compatible with round Ø125 mm air ducts.
DESIGN FANS

The casing is made of expanded polypropylene (EPP) plates, 15-30 mm thick, possessing high heat- and sound-insulating properties.The unit is equipped with service panels for convenient maintenance of filters and heat exchanger.The spigots are located at the top of the unit and are rubber sealed for airtight connection to the air ducts.

Single-phase three-speed external rotor motors with centrifugal impellers and forward curved blades.Integrated motor overheating protection with automatic restart.

HEAT RECOVERY AIR FILTRATION

The KOMFORT S5 230 unit is equipped with a plate counter-flow polystyrene heat exchanger for heat recovery. In the unit condensate is collected and drained to the drain pan under the heat exchanger.The KOMFORT S5 230-E unit is equipped with an enthalpy plate counter-flow heat exchanger for enegry (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.

FREEZE PROTECTIONThe freeze protection of the heat exchanger is activated by shutdown on the supply fan as follows: in case of freezing danger communicated by the temperature sensor the supply fan turns off for the time required for defrosting of the heat exchanger with the warm extract air flow. After freezing danger is no longer imminent, the unit reverts to the standard operation mode.

The built-in G4 supply filter and G4 extract filter provide air filtration.A F8 supply filter (specially ordered accessory) may be used for efficient supply air filtration.

CONTROL AND AUTOMATION

The units have integrated control system based on the mechanical three-speed speed switch CDP-3/5 (KOMFORT S5 230 S3) or sensor three-speed speed switch SGR-3/1 (KOMFORT S5 230 S4) and power cable with mains plug.
The control unit is integrated in the unit casing.The power and ground cables are connected to the control unit via the cable glands on the side of the unit.

MOUNTING

The units are designed for wall and floor mounting.The universal casing design provides left- and right-sided mounting.
