inVENTer iV-Twin+

Double power for single rooms

Available from summer 2019

  • Single room ventilation – now with a 200-mm pipe
  • Higher energy efficiency through horizontal separation of airflow rates
  • Improved moisture protection thanks to powerful extract air mode
  • Demand-controlled ventilation via temperature sensor with cold protection mode to prevent excessive cooling

  • Greater functionality in single room ventilation

    Two adapted Xenion® fans run in push-pull operation in the iV-Twin+, whereby one fan supplies fresh air and the other simultaneously removes the used air from the room. The fans alternate every 70 seconds. If required, both fans can also switch to extract air mode to remove stale, moist air quickly and reliably.
    The "Twin" principle is based on a consistent separation of the airflow within the device via vertical separating elements in the inner cover, wall sleeve and weather protection hood. Heat recovery is ensured via two thermal accumulators with ceramic honeycombs.

    Powerful single room ventilation
    The inVENTer iV-Twin+ combines two ventilation devices in one, making it ideal for single room ventilation. Unlike with single room ventilation units with recuperative heat exchangers, no frost protection strategy or separate condensate removal is necessary. The iV-Twin+ is a highly functional ventilation system that can be used in bathrooms and kitchens, and also in individual rooms in residential and office buildings as well as retirement homes.


    The iV-Twin provides an option for single room ventilation to our customers. A wall break enables a ventilation of up to 25m². Therefore this system is especially suited for example for nursing homes and hospitals, single room apartments as well as kitchens and bathrooms.

    Easy installation
    The inVENTer iV-Twin+ has a diameter of 200 mm and therefore requires a wall opening of just 225 mm. This can be provided quickly and easily either by drilling a core hole or, in new buildings, via the Simplex wall installation system. 
    Installation is possible from a wall thickness of 270 mm. Vertical airflow separators are pre-assembled in both the inner cover and weather protection hood, further reducing the installation time.

    Thanks to its new design concept, the iV-Twin+ blends even more harmoniously into your living space. The inner cover and weather protection hood are similar in appearance to the iV ventilation systems and are available in a Flair or Nova design – the installation process is also similar. Naturally, the iV-Twin+ can also be controlled via all common controller systems. In the bathroom, the new inVENTer Hygrostat HYG18 provides on-demand ventilation with humidity monitoring.

  • Efficient without paired operation

    The ceramic honeycombs in the two thermal accumulators are designed as half cylinders with large surfaces and achieve a heat recovery of well over 80% in the iV-Twin+. The new device is thus eligible for support from the KfW bank. The iV-Twin+ features one of the largest ceramic thermal accumulators with a honeycomb structure on the market.

    The iV-Twin+ single room ventilation device can be operated at low fan speeds, whereby it carries out the air exchange extremely quietly. The standard integrated temperature monitor prevents excessive cooling of the living space when the outside temperature is very low. A wind pressure stabiliser also prevents elevated running noise in the event of strong winds. The device's filters ensure a high standard of hygiene and can be used either as pollen, fine or activated carbon filters.

    Our extensive experience in the ventilation industry since 1999 led us to identify and meet the demand for a device to provide single room ventilation. Our Twin concept for a single room ventilation system from 2007 has now been adapted and made even more efficient and comfortable. The result is the most powerful single room ventilation unit with reversible technology on the market.
