e² with heat recovery

Controlled home ventilation with the e² with heat recovery

e² series

The e² is one of the smallest decentralised fans with heat recovery in domestic ventilation.

Special features

The e² is one of the quietest units in its class, making it perfect for use in living rooms and bedrooms. With only 0.09 W/m³/h converted power consumption, it is also unsurpassed in energy efficiency.

The e² is based on the principle of regenerative heat exchange. With the help of the modern manufacturing processes, we have succeeded in developing a compact heat accumulator made of a ceramic composite material that delivers a maximum heat supply efficiency of 96%. The combination with highly efficient ec motors and an intelligent control system has enabled LUNOS to develop one of the most economical fans.

Installation

The e² can be used in new buildings as well as in renovation projects. In new buildings, it is placed between the bricks with the help of a wall installation housing or retrofitted in a renovation project with the help of a 162 mm core drill hole. The wall only needs to be at least 300 mm thick. The wiring is done directly from the control unit, which is installed in a standard electronic box or in the sub-distribution. From there, only three wires are required, which are supplied with 12 V safety extra-low voltage.

Approval

The e² has, of course, been approved by the building authorities.
