Single Room Wall Mounted Ductless Heat Energy Recovery Ventilator

Main Features:

1. Fresh air supply and extract stale air from the room alternately
2. Maintain heat regeneration and indoor humidity balance
3. Reduce heating and air conditioning costs
4. Easy to install through the internal wall with hole diameter from 160-170mm
5. The auto shutter can prevent the insects entering and the cold air flowing backward when the unit stops
6. Consume little energy
7. Silence operation
8. Prevent excessive indoor humidity and mould build-up
9. High efficient ceramic energy regenerator
10. The outer hood can prevent rain draining back and birds nesting

Reversible EC-Fan

The reversible axial fan with a EC motor. Due to the applied EC technology the fan is featured with low power consumption and silent operation. The fan motor has integrated thermal overheating protection and ball bearings for long service life.

Ceramic Energy Regenerator

The high-tech ceramic energy accumulator with regeneration efficiency up to 97% ensures extract air heat recovery for warming of supply air flow. Due to the cellular structure the unique regenerator has a large air contact surface and high heat-conducting and heat-accumulating properties.

The ceramic regenerator is treated with an antibacterial composition which prevents bacteria growth inside of the energy regenerator. The antibacterial properties last for 10 years.

Air Filters

The two integrated air filters with total filtration rate G3 provide supply and extract air filtration. The filters prevent ingress of dust and insects into the supply air and contamination of the ventilator parts. The filters also have antibacterial treatment.

The filter cleaning is done with a vacuum cleaner or water flushing. The antibacterial solution is not removed. F7 filter is available as a specially ordered accessory, but when installed, it reduces the air flow down to 40 m³/h.

Operation Modes 

Ventilation Mode: The ventilator runs in the air extract or air supply mode with a set speed. In the case of synchronous operation of two connected ventilators, one unit operates in the supply mode and the other one in the extract mode.Regeneration Mode:The ventilator runs in two cycles,65 seconds each, to provide heat and moisture regeneration.

Working Principle

The reversible operation of the ventilator enables energy regeneration and consists of two cycles:

CYCLE I

The polluted warm air is extracted from the room and while passing the ceramic energy regenerator, the recuperator will absorb the heat and moisture. In 65 seconds, as the energy regenerator gets warmed, the ventilator automatically switches to the supply mode.

CYCLE II

The fresh, but cold outdoor air flows through the heat regenerator and absorbs the accumulated heat and moisture so that the temperature of supply airflow will close to the room temperature. In 65 seconds, when the energy regenerator gets cold, the ventilator switches to the air extract mode. The cycle starts from the beginning.

Applications

The ventilator is designed to ensure continuous mechanical air exchange in houses, offices, hotels, cafes, conference halls and other residential and public premises. The ventilator is equipped with a ceramic heat exchanger that enables supply of fresh filtered air heated by means of extract air heat regeneration. The ventilator is designed for through-the-wall mounting and is rated for non-stop operation. Transported air must not contain any flammable or explosive mixtures, evaporation of chemicals, sticky substances, fibrous materials, coarse dust, soot and oil particles or environments favorable for the formation of hazardous substances (toxic substances, dust, pathogenic germs).
