ᐅ Is decentralized ventilation with a cross-counterflow heat exchanger still a current solution?

Hello forum,

I want to install a decentralized ventilation system in my older apartment (built in the 1960s, 3 rooms, 70m² (750 sq ft)). Since I am sensitive to clicking noises, I am hesitant to choose a pendulum fan. From my online research, cross-counterflow heat exchangers seem to be the ideal solution (though they are a bit more expensive, which is not a problem for me). Unfortunately, I simply cannot find any current models. The only decentralized ventilation system with a cross-counterflow heat exchanger I can find is the Vitovent 200-D. However, it appears to have been on the market for a very long time, and there are very mixed reviews online.

Can you recommend any more recent models?

Good luck

Then take a look at InnovaTech, Wolf, Zehnder — at least these manufacturers offer current models that are not reversible. I’m not allowed to post links...

Thank you. The Zehnder Comfo Air 70 looks especially interesting. Although it has already been on the market for 6 years. I’m surprised that there aren’t more new models available.

It’s such a simple technology that there’s no real reason for changes—except maybe in terms of Wi-Fi integration, humidity control, or similar features. But no changes to the ventilation technology itself.
It’s like repainting a red Golf every two years, installing a new radio, and then selling it as a completely new car.
