Description
APPLICATION

Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.For arranging of controlled energy saving ventilation systems.Heat recovery minimises ventilation heat losses.Controllable air exchange for creating the best suitable indoor microclimate.Compatible with round Ø160, 250 and 315 mm air ducts.

DESIGN

The casing is made of double-skinned aluzinc panels, internally filled with up to 25 mm mineral wool layer for heat and sound insulation.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

High-efficient external rotor EC motors and centrifugal impellers with backward curved blades are used for air supply and exhaust.EC motors have the best power consumption to air capacity ratio and meet the latest demands concerning energy saving and high-efficient ventilation.EC motors are featured with high performance, low noise level and totally controllable speed range.Dynamically balanced impellers.

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.

MOUNTING

The unit is suitable for floor, ceiling or wall mounting using fixing brackets.The correct mounted unit must provide free condensate collection and drainage as well as good access for servicing and filter replacement.The service access is on service panel side, leftwards along supply air flow.

HEAT RECOVERY

The unit is equipped with an aluminium rotor heat exchanger with high heat recovery efficiency.As compared to plate heat exchangers, the rotor heat exchangers are distinguished with higher heat recovery efficiency, ability to maintain comfortable air humidity and extremely low freezing danger that is nearly excluded in rated temperature and humidity conditions.Heat recovery is based on utilization of heat energy contained in the extract air stream for heating up of supply air stream. Extract air transfers most of its heat to the intake air flow. Heat recovery reduces heat energy 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.

AIR FILTRATION

The built-in G4 pocket supply filter and G4 cassette extract filter provide efficient air filtration. Optionally, an F7 supply filter may be used.

CONTROL AND AUTOMATION

The unit incorporates an integrated control system with a wallmounted control panel and a sensor LCD display.The standard delivery set includes a 10 m cable for connection of the unit and the control panel.Automation functions:

  • Activating/deactivating the unit.
  • Setting required speed for the supply and extract fan. Each speed is individually adjusted during set-up.
  • Automatic heater activation/deactivation and smooth heat output control. Heater overheating protection. Cooling of the heater at the end of the heating cycle.
  • Setting and maintaining room air temperature.
  • Setting week-scheduled operation of the unit.
  • Filter clogging control with a motor meter.
  • System shutdown on signal from a fire alarm panel.
  • Controlling servo-driven supply and exhaust air dampers (to be ordered separately).
  • Cooler control (available separately).
  • Automatic rotor activation and shutdown.
