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 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 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.

AIR FILTRATION

The built-in F7 cassette supply filter and G4 cassette extract filter provide efficient air filtration.

HEAT RECOVERY

The unit is equipped with a plate 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 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.The drain pan under the heat exchanger block is used for condensate collection and drainage.

CONTROL AND AUTOMATION

The unit incorporates an integrated control system with a wallmounted 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:

  • Activating/Deactivating the unit.
  • Setting required fan speed.
  • Setting and maintaining supply air temperature.
  • Displaying indoor temperature.
  • Setting week-scheduled operation of the unit.

Automation functions:

  • Controlling supply and exhaust air dampers (available separately).
  • Filter clogging control.
  • Preventing overheating of the electric heating elements.
  • Disabling heater activation during the fan shutoff.

The control system is short circuit protected with an automatic circuit breaker.

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.
