FUNCTIONAL PRINCIPLE

Fresh air flows through the filter and heat exchanger. The air is fed into the room by means of the integrated fan.
Used exhaust air is extracted by the fan and discharged outside via the heat exchanger. Particularly in the winter months, the heat and humidity in the exhaust air is transferred to the supply air via the enthalpy membrane of the heat exchanger. In this way, a considerable proportion of the energy generated during ventilation is recovered and is not lost.
In the summer months, the process may be reversed. Fresh supply air is transported inside by the fan via the heat exchanger. The heat and humidity of the fresh air are transferred to the exhaust air via the enthalpy membrane of the heat exchanger. Cooler and drier supply air flows into the room. In the SEPHYR series, the supply and extract air volume flows are completely separated. There is no transfer of impurities, odours or bacteria (germs).

Control unit

The SEPHYR 250D is controlled via the ZS-SEPHYR COMFORT control unit. The intuitive and uncomplicated user interface of the control unit enables effortless handling of the ventilation unit in just a few simple steps.

A POWERFUL TRIO

Heating Coil
Heat Exchanger
Fan Unit

At the heart of the SEPHYR series is an intelligent trio: a highly efficient heating coil, an energy-efficient heat exchanger and a powerful fan unit. These three main components are the key to improved indoor air quality with efficient energy utilisation.

• Electric pre-heater coil for active frost protection during the winter months
• Dynamic adjustment of the heating capacity
• Post-heater coil to increase the supply air temperature (optional)
