Decentralised ventilation SEVi Multi

SEVi Multi with recuperative enthalpy heat exchanger

The SEVi Multi (decentralised ventilation SEVi Multi) was developed to ventilate several rooms simultaneously. Indoor bathrooms can be actively integrated into the ventilation concept with the SEVi Multi. The warm exhaust air from the bathroom is reused to a large extent. A large part of the heat from the extract air (up to 89 %) is transferred to the supply air through the duct counterflow heat exchanger.

Structure of the product

The SEVi Multi (decentralised ventilation SEVi Multi) combines state-of-the-art technology in a slim ventilation housing. On the façade, 2 weather protection bonnets prevent water from entering the ventilation system. Inside, an elegant and slim inner panel covers the ventilation housing including the mounting box. The mounting box of the ventilation unit is recessed into the masonry and can also be installed directly under a window. The load of the window is absorbed by the ventilation unit’s own statics (observe maximum values: see installation instructions). The mounting box contains the device insert, which can be revised without tools. The unit insert contains 2 high-pressure EC centrifugal fans from ebm-papst, an enthalpy heat exchanger, the control of the ventilation system, 2 filters and optionally an automatic damper lock. The filter of the SEVi Multi decentralised ventilation system can be changed without tools via the inner panel.

Integrated control element

The integrated control simplifies the installation of the ventilation system, as there is no need for a remote control element. The control is easily accessible and simple to operate. The ventilation system has 4 different ventilation levels and can be deactivated. The filter indicator signals when you should look at the filters and possibly clean or replace them. There are also a number of special functions:

With the optional motorised flap control, the flaps close even in the event of a power failure.
Switch-off function can be deactivated
Frost protection Disbalance control
Adjustment mode: Supply and extract air volume flows can be readjusted directly at the control unit when using a duct.
