Combi 400 Polar Top – energy-efficient and compact

Ventilation, comfort heating and comfort cooling in one unit

The Combi 400 Polar Top combines ventilation, comfort heating and comfort cooling in a space-saving unit that requires minimal room while maintaining a stable and even temperature throughout the home. Advanced control technology optimises energy consumption and delivers overall energy savings.

Two heat recovery technologies – passive and active

The Combi 400 Polar Top is equipped with both a highly efficient counterflow heat exchanger, ensuring optimal passive heat recovery, and a built-in heat pump that actively regulates the supply air temperature – heating or cooling as needed.

Built-in frost protection

The new Combi 400 Polar Top includes an integrated pre-heating element that effectively prevents ice from forming in the heat exchanger during winter. The pre-heating element ensures that the outdoor air supplied to the unit never drops below -3 °C. It regulates gradually to avoid unnecessary energy use while helping to maintain consistently high heat recovery.

HMI panel and gateway included

Ventilation and heat pump control can be managed directly via the HMI panel or from your smartphone. Once connected to the internet through a Nilan Gateway, the unit can be operated via the app, available free of charge in both the App Store and Google Play.

Optimise your product portfolio and offer your customers the very best in ventilation and heat recovery with the Combi 400 Polar Top.
