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.

Protože entalpický výměník přenáší i vlhkost, mohlo by se zdát, že riziko vzniku plísní je vyšší. Ve skutečnosti však veškerá vlhkost odchází pryč spolu s čerstvým vzduchem, takže riziko vzniku plísní nehrozí.

Naše doporučení je v zimních měsících jednotku nikdy nevypínat, aby byl odvod vlhkosti zajištěn nepřetržitě. Pokud byste přesto potřebovali jednotku odstavit, vyjměte výměník, propláchněte jej čistou vodou, důkladně vysušte a teprve poté jej vraťte zpět.

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.

Feel free to contact us with any unit model. We will do our utmost to provide you with a 100% compatible exchanger, regardless of the type of ventilation unit you have.

In some cases, the exchangers we supply are identical to the original parts used by the unit manufacturers, and in many cases, our exchangers are even of higher quality. However, we must clearly state that we are not official distributors of spare parts from the unit manufacturers. Transparency is very important to us.

An enthalpic heat exchanger should be used all year round. In winter, it prevents excessive drying of the indoor air, and in summer, it helps maintain comfortable humidity and temperature by reducing heat transfer and returning part of the moisture to the fresh supply air. This increases comfort and saves energy in every season.

No, caring for an enthalpic heat exchanger is no more demanding than for a standard one. Maintenance is described in the user manual and in our video guide. In short: first vacuum the exchanger with a soft brush attachment, then rinse it with clean water (max. 50 °C). Never use compressed air or a pressure washer.

After rinsing, allow all water to drain completely. Remaining moisture can be carefully blown out with a regular hairdryer, but always use cold air only. Once the exchanger is completely dry, place it back into the unit in the same orientation as before removal.

We do not recommend using chemicals for cleaning. Only if disinfection is absolutely necessary may a weak solution of peracetic acid be used, followed by very thorough rinsing with clean water.

Yes, the use of an enthalpic heat exchanger is completely safe. The membrane is designed to allow only water vapor molecules to pass through, while blocking bacteria, odors, and harmful substances. All enthalpic heat exchangers we offer are hygienically tested and certified.
