The e²: With heat recovery

The e² series

With the new heat exchanger, the e² from the e² series is one of the smallest, lightest and most sustainable decentralised fans with heat recovery in home ventilation in the single-channel device class worldwide.

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 Polymer based composite plastic 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.

Extra

The products of our e² series all have the option of summer ventilation.

Approval

The e² has received building authority approval from the DIBt. In addition, the e² FR with pipe, which is used in the USA and Canada, for example, has received its approval, which is granted on the North American continent according to even stricter rules (e.g. for more fire-resistant material).

Information on the technical data

Show technical data

1) Silvento V are fan inserts that still require a flush-mounted or surface-mounted housing.

2) Silvento KL are complete single-pipe fans that are clamped into pre-wall constructions. Silvento KL single-pipe fans fit into the flush-mounted housings of the LUNOS Skalar series.

3) The specified values are achieved at 20°C, 1013hPa and 1.2kg/m3 ambient air density and (unless otherwise specified) are achievable between free-blowing condition and 60 Pa disturbance pressure in accordance with DIN18017-3.

4) When designing the volume flows, please observe the pressure-volume flow characteristics provided by LUNOS and the specifications of the abZ (DIBt approval)

5) Sound power level: The sound power level indicates how "loud" a device is. The value is independent of the distance.

6) Volume flow rate of the ALD-SV with a straight arrangement of the sound attenuation elements.

7) Max. achievable WBG according to EN13141-8 with reference volume flow rate.

8) At 70 % of the maximum volume flow rate, in accordance with ErP Directive, EU Regulation 1254/2014.

9) According to LÜA (test specification) of the DIBt and EN13141-8 max. achievable exhaust air volume flow free-blowing at 20°C and 1013hPa ambient conditions and 1.2kg/m3 ambient air density.

a) According to LÜA (test specification) of the DIBt, see also proof of usability (abZ), when using the wall-mounted housing 9/MRD as insulation, without 9/MRD 2% deduction.

b) According to LÜA (test specification) of the DIBt, max. achievable value.

c) According to EN 13141-8 with reference volume flow, see also certificate of usability (abZ) of the DIBt.

d) According to LÜA (test specification) of the DIBt and EN13141-7 max. achievable exhaust air volume flow free-blowing at 20°C and 1013hPa ambient conditions and 1.2kg/m3 ambient air density.

e) According to EN 13141-7 at reference volume flow rate, see also proof of usability (abZ) of the DIBt.

f) Determined by the Passive House Institute (PHI), see PHI certificate.

g) Sound pressure level at 1m distance, single-point measurement. All figures are mathematically rounded.
