RECUTECH are equipped with the latest enthalpic membrane METALPIC. They excel in top-class heat and humidity recovery, high resistance to pressure differences, and long service life. They are among the most advanced enthalpic heat exchangers currently available on the market.

ZERN are fully plastic enthalpic heat exchangers, very efficient, with slightly better moisture transfer, but with higher pressure loss.

No, never block the condensate drain.

Even though enthalpic heat exchangers produce only a minimal amount of condensate due to moisture transfer, in severe frost and specific humidity conditions, condensate can still occur. Blocking the drain could cause irreversible damage to your unit.

Since an enthalpic heat exchanger also transfers humidity, it might seem that the risk of mold is higher. In reality, however, all moisture is carried away with the fresh air, so there is no risk of mold growth.

Our recommendation is to never switch off the unit during the winter months, so that moisture is continuously removed. If you still need to shut down the unit, remove the exchanger, rinse it with clean water, dry it thoroughly, and only then reinstall it

Yes, installation is simple. Just follow the instructions provided with your unit. As with a standard exchanger, it needs to be removed occasionally for cleaning – the process is the same, except that you put the enthalpic exchanger back in instead.
