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.
