FEATURES

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 Ø 125 to 315 mm air ducts.

DESIGN

The casing is made of double-skinned aluzinc panels, internally filled with 25 mm 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

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

HEAT RECOVERY

The 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 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).

FREEZE PROTECTION

The electronic protection system based on bypass and heater is used for freezing protection of the unit in cold seasons. The bypass damper is opened and the heater is turned on automatically according to temperature sensor readings. Cold intake air passes by the heat exchanger and is warmed up to set temperature in the heat exchanger. Synchronously extract air that passes by the heat exchanger is used for its defrosting. After a freezing danger is over the bypass damper is closed, the heater is turned off. The heat exchanger reverts to the normal operation mode.

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.

  CONTROL AND AUTOMATION

The unit incorporates an integrated control system with a wall-mounted control panel and LCD display. The standard delivery set includes a 10 m cable for connection of the unit and the control panel. Control panel functions:

  • Switching on/off.
  • Three-speed fan selection, selecting heating/cooling modes (if connected to duct heater).
  • Temperature display.
Automation functions:
  • Maintaining supply air temperature set from the control panel by controlling the circulation pump and actuating the heat medium regulating valve; input from the heat medium flow switch (pump alarm).
  • Safe start-up/ shutdown of the fans, warming up of the water heater before start-up; return heat medium temperature control when the fan is off.
  • Freezing protection of the water heating coils by the exhaust temperature sensor and the return heat medium temperature sensor.
  • Control of the compressor and condensing unit of the water cooler by the room temperature sensor (for the models equipped with a duct air cooler).
  • Actuating the external air dampers with a return spring.
  • Unit operation according to week schedule (set at the system setup).
  • Unit shut down at signal from the fire alarm system.
  • Smooth bypass damper control in the bypassing mode to prevent the heat exchanger freezing.
AIR HEATER

The unit is equipped with an electric heater for operation during cold seasons at low outside temperature. The integrated electric heater is activated to warm up supply air flow if set indoor air temperature may not be reached by means of heat recovery only. Smooth heat output control ensures automatic supply air temperature maintaining. Two integrated overheat protection thermostats, one actuated at +60 °C with automatic restart and the other one actuated at +90 °C with manual restart.
