Install one of modern single room air handling units with heat recovery MICRA!
The single room air handling unit with heat recovery MICRA is the best cost–saving solution for creating of energy saving ventilation of separate rooms in apartments, cottages, social and commercial premises.
Single-room air handling units MICRA – efficient, reliable, energy saving ventilation:
- clean fresh air supply to the premises
- stale extract air removal from the premise
- clean air free of dustand insects
- no excessive humidity and mould
- silent operation
- heat regeneration
- air warming up to set temperature (MICRA 150 E)
- reducing heating costs in winter and air conditioning costs in summer
- low energy demand
- non-stop operation
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.
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
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.
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.
Air supply and exhaust
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.
Condensate drain pan
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.
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%.
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.
