Description
Description
  • MICRA 150 E is a single-room air handing unit with air warming up function. It is designed to provide the ideal single-room ventilation of social and commercial premises, flats and cottages. MICRA 150 E is the most suitable solution for arrangement of ready-made and refurbished premises. It has easy mounting without air ducts.
FEATURES CASING
  • Efficient supply and exhaust ventilation of separate premises (rooms)
  • Posistor 350 W air heater with overheating protection
  • Polystyrene plate counter-flow heat exchanger with recuperation efficiency 82-92%
  • EC fans with low energy demand (9 to 40 W)
  • Integrated automation with 3 operation modes (from 60 up to 150 m3/h)
  • Silent operation (30-38 dBA)
  • Air cleaning with two built-in G4 filters
  • Easy mounting
  • Compact sizes
  • Metal polymer coated casing decorated with mirror-polished stainless steel.
  • 10 mm foamed synthetic rubber layer provides heat- and sound-insulation.
  • The modern unit design let it match well with any interior type.
  • The front panel is easily opened for the unit servicing (e.g. for filter cleaning or replacement) and fitted with a protecting opening sensor that cuts power supply off if the panel is opened.
  • Air is supplied to the unit and exhausted from the premise through two Ø 125 mm air ducts.
AIR SUPPLY AND EXHAUST
AIR FILTRATION
  • High-efficient EC motors with external rotor and forward curved blades are designed for air supply and exhaust.
  • The fan motors have built-in overheating protection and ball bearings for longer service life.
  • Due to EC technologies Micra 150 E is featured with low energy demand and reliable operation.
  • Supply and exhaust air flows are cleaned with two built-in G4 filters.
  • The filters serve to provide supply of fresh air free of dust, insects and prevent the unit components from soiling.
CONDENSATE DRAIN PAN OPERATING LOGIC
  • Some condensate that may be generated during heat recovery process is collected in a special drain pan.
  • As the drain pan is filled with condensate, the unit switches automatically off which is confirmed by a light indicator on the control panel.
  • Remove condensate from the drain pan and restart the unit to continue the unit operation.
  • The intake air from outside flows through the filter and the heat exchanger and is supplied to the room with the supply centrifugal fan.
  • Warm stale air from the room flows through the filter and the heat exchanger and is exhausted outside through the wall by the exhaust centrifugal fan.
  • In the heat exchanger heat energy of warm extract air from the room is transferred to clean cold air flow from outside.
  • Heat exchange results in minimization of heat losses and lower heating costs.
  • The extract and supply air flows are fully separated, so no contaminations, odours and microbes come to supply air flow.
 
 
 
 
HEAT EXCHANGER HEATER
  • The unit incorporates a high-tech plate counter-flow polystyrene heat exchanger with heat exchange efficiency 82-92%.
  • In winter period the heat exchanger utilizes heat energy of extract air to warm up intake air and decrease the operating load on the heating system.
  • In summer period supply air is cooled down by colder intake air.
  • The unit is equipped with a semiconductor posistor heater which is used to warm up supply air up to the comfortable air temperature and has a number of advantages compared to standard tubular electric heaters - maintaining of rated operating temperature combined with operational economy, fire safety (no overheating), environmental friendliness, self-regulation, high electric durability, high specific power, low infrared radiation, easy and reliable maintenance.
  • The heater efficiency is in direct proportion to the air flow that goes through the heater and reaches 90-95%.
FREEZING PROTECTION
  • The air handling unit MICRA 150 E is equipped with a built-in freezing protection.
  • During heat recovery in cold season thermal energy of warm extract energy is transferred to cold intake air.
  • If some condensate is produced in the heat exchanger, it is collected in a specially designed drain pan.
  • The electronic freeze protection is applied to prevent condensate freezing during cold outside temperatures.
  • If exhaust air temperature at outlet from the heat exchanger the supply fan is stopped.
  • Warm extract air warms the heat exchanger up and the exhaust air temperature rises.
  • After that the supply fan is turned on and the unit reverts to the previous operation mode.
CONTROL AND OPERATION MODES
  • The unit is equipped with a control panel.
  • The delivery set includes a remote control panel.
  • The control system supported five operation modes:
    • – 1 speed – air capacity 60 m3/h and air warming up function. 
    • – 2 speed – air capacity 105 m3/h and air warming up function. 
    • – 3 speed – air capacity 150 m3/h and air warming up function.
  • The following functions are available:
    • Extra heating of supply air;
    • High speed activation timer adjustable from 20 to 60 minutes;
    • Fan speed adjustment;
    • Week-scheduled operation;
    • Filter replacement and alarm indication.
MICRA 150 E VENTILATION SYSTEM ARRANGEMENT EXAMPLE  
  • Install one or several MICRA 150 E unit in each premise to be ventilated.
  • One unit is capable to provide efficient ventilation of up to 60 m2 area.
  • Ventilation system based on the single room air handling unit with heat recovery MICRA 150 E provides permanent air exchange in a premise, saves heat in winter and cold in summer.
  • The air handling unit MICRA 150 E is mounted on a face wall from inside.
  • The wall thickness must be no less than 100 mm.
  • First mark the holes for the air ducts with a cardboard master plate included into the delivery set.
  • Drill the holes and fix the cardboard master plate to the wall with dowels and screws.
  • Insert the air ducts into the holes.
  • Use the metal master plate to fix the air ducts in a required position and to align the pipes and the air ducts.
  • Mount a double metal hood on outer wall side to protect the unit from water ingress and outer objects.
  • After positioning of the air ducts between the outer hood and the metal plate fill the gaps between the air ducts and the wall with a mounting foam through special slots in the metal plate.
  • After foam hardens remove the metal master plate and cut protruding parts of the air ducts to be flush with wall surfaces.
  • For mounting of the unit casing open the decorative panel and remove the heat exchanger.
  • While mounting the unit direct the branch pipes to the plastic air ducts and fix it to the wall with dowels and screws.
  • The unit is supplied with a pre-wired power cable and a socket.
  • The unit may be connected to the fixed wiring system through terminal leads.
  • For doing that disconnect the power cable from the terminal box and connect the leaded outside power cables.
  • After completing the casing mounting and wireworks re-install the heat exchanger and close the front panel. The unit is ready for operation.
  • To arrange the most optimal ventilation system supplement the MICRA 150 E unit with the extract fan VENTS VN in the bathroom.
