Reverse technology for exhaust air rooms.
The Lunos ego was developed for optimum ventilation with heat recovery in bathrooms, WCs, and kitchens.
It combines supply and exhaust air by means of two small fans located inside the fan. The ego is one of the world’s smallest fans for domestic ventilation with heat recovery in the two-channel unit class.
The Lunos ego operates in accordance with the principle of the regenerative heat exchanger. A storage element is charged with heat as for the e². However, this is so skillfully distributed via two fans so that supply and exhaust air can be transferred simultaneously. A second unit is not required for operation. This system can also be switched in an exhaust air mode in which a very high flow rate of 45 m³/h is discharged in order to enable the swift inflow of fresh air into a room.
The very low power consumption ensures high energy-efficiency, making an active contribution to environmental protection and at the same time saving you money. The ego thus achieves the energy efficiency class B.
The compact heat store made of a ceramic composite material with an extraordinary honeycomb structure provides high thermal efficiency. The so-called acuvent storage stone is located at the center of the airflow of an ec-motor with axial fan. By means of a reversing airflow arising via systematic change of direction of the fan, the ceramic is charged with the thermal energy of the room air and transfers this back to the outside air supplied.
The ego is among the smallest de-centralized fans for home ventilation with heat recovery in the world in the class of two-way devices. By applying state of the art production processes we have managed to develop compact heat storage of ceramic composite material which provides a mean thermal efficiency of 90.6 or 85 %.
If a LUNOS ventilation system has already been installed, the Lunos ego can be replaced in existing outside wall air outlets of the 160 series.
Lunos ego can be used in new constructions and in redevelopment work. In new constructions, they are installed between the bricks with the aid of a wall rack or installed subsequently e.g. in the case of redevelopment work using a 162 mm large core drill hole. The wall must be at least 30 cm thick.
