Šis entalpinis šilumokaitis yra matmenimis identiškas „Viessmann Vitovent 300-W“ šilumos atgavimo įrenginių šilumokaičiams ir yra įprastai montuojamas šiuose įrenginiuose.

Tačiau tai nėra originali atsarginė dalis, kurią tiekia ir sumontuoja įrenginio gamintojas, todėl jos naudojimą nusprendžia šilumos atgavimo įrenginio naudotojas.

RFK+ / RFC+ serija yra visiškai entalpinė alternatyva REK+ priešsroviniams aliuminio šilumokaičiams, kuri, dėka novatoriškos technologijos, siūlo ne tik iki 90 % šiluminį efektyvumą, bet ir labai aukštą drėgmės efektyvumą. Dėl tų pačių matmenų aliuminio ir plastiko šilumokaitį taip pat lengva pakeisti be papildomų šilumos atgavimo įrenginio modifikacijų.

Kuo ypatingas RECUTECH entalpinis šilumokaitis?


Didelis šiluminis efektyvumas – DMedžiagoms, kurios leidžia formuoti ir tokiu būdu padidinti šilumos perdavimo paviršių, šilumos perdavimo efektyvumas siekia iki 90 %. Nenaudojame tarpiklių, nes jų nereikia.

Drėgmės perdavimo efektyvumas iki 75%.

Sandarumas – Kaip ir esate įpratę prie RECUTECH keitiklio, jis yra sandarus. Mes nesileidžiame į kompromisus net su entalpija. Mes juos visus išbandome ir jus pasieks tik tvirti gabalai.

Optimalus santykis

Didelis atsparumas slėgio disbalansui – Dėl naudojamų medžiagų standumo mūsų šilumokaičiai gali atlaikyti 800 Pa slėgio disbalansą. Jie taip pat leidžia naudoti konfigūraciją, kai vienas įrenginio ventiliatorius įsiurbia orą, o kitas stumia.

Didelis selektyvumas – mūsų membrana yra labai selektyvi. Jis praleidžia tik vandens garus, jokių kitų dujų. Selektyvumas patvirtinamas bandymais.

Lengvas pakeitimas esamose instaliacijose – Dėl tų pačių matmenų ir panašių šiluminio efektyvumo parametrų įrenginyje esantį šilumokaitį galite lengvai pakeisti entalpiniu.

Kaip šie parametrai buvo pasiekti?


Tai daugiausia lemia unikalios medžiagos, vadinamos „Metalpic“, naudojamos „Recutech“ entalpiniuose keitikliuose, naudojimas. Ši medžiaga buvo sukurta tik šiam tikslui ir ją sukūrė „Recutech“. Tai sumuštinio tipo medžiaga, kurioje kiekvienas komponentas atlieka savo aiškiai apibrėžtą funkciją.

Jį sudaro specialiai apdorotas išplėstas aliuminis su kuo didesniu atviru plotu. Pagrindinė jo funkcija – sukurti atraminę konstrukciją antrajam komponentui, kuris yra labai plona polimerinė membrana. Kodėl aliuminis? Nes ši medžiaga labai gerai praleidžia šilumą ir yra lengvai perdirbama.

Antroji sumuštinio dalis yra polimerinė membrana. Pagrindinė jo funkcija yra perduoti drėgmę ir užtikrinti gautos medžiagos sandarumą. Tai jonų mainų membrana, kuri yra selektyviai pralaidi.

Dėl išplėsto metalo atramos membrana gali būti labai plona, o kuo plonesnė membrana, tuo geriau perduodama drėgmė. Abi šio sumuštinio dalys sujungiamos laminavimo būdu.

entalpijos lamelės

Ši medžiaga vėliau apdorojama kaip klasikinė aliuminio folija REK ir REC serijos keitikliams. Šiame procese abi šio sumuštinio dalys, kaip ir aliuminis, turi susidoroti su santykiniu pailgėjimu tempimo metu.

Dėl šių savybių galima sukurti lamelę, kuri formavimo metu sutvirtinama ir padidinama jos šilumos bei drėgmės mainų paviršiaus plotas. Dėl tempimo membrana tampa dar silpnesnė ir, kaip rašėme aukščiau, kuo ji plonesnė, tuo geriau perduodama drėgmė.

    What is the difference between RECUTECH and ZERN enthalpic heat exchangers?

    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.

    Can I block the condensate drain if I replace a standard heat exchanger with an enthalpic one?

    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.

    What about mold formation in an enthalpic heat exchanger?

    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

    Can I install an enthalpic heat exchanger by myself?

    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.

    Why do you include a disclaimer stating that the product is not an original spare part?

    In any case, 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.

    Should I use an enthalpic heat exchanger in summer as well, or only in winter?

    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.

    Does an enthalpic heat exchanger require more maintenance than a standard one?

    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.

    Is the use of an enthalpic heat exchanger safe for health?

    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.

    Is it guaranteed that using an enthalpic heat exchanger will achieve ideal humidity levels?

    An enthalpic heat exchanger will always help improve indoor humidity, as it transfers part of the moisture from exhaust air back into the fresh supply air. It cannot be guaranteed that ideal levels (typically 40–60%) will be achieved, since the final humidity also depends on other factors – such as household habits, number of occupants, natural moisture sources, and outdoor climate conditions.

    However, we can guarantee that humidity will improve, because it is physically impossible for the return of moisture not to contribute to higher values.

    Is it possible to insert the enthalpic heat exchanger into the unit in the wrong orientation?

    The enthalpic plate works the same from both sides, so the orientation of the plate itself does not matter. However, it is essential that after cleaning the exchanger is always reinstalled in the same orientation, ensuring that the channels for fresh air remain for fresh air and the channels for exhaust air remain for exhaust air.

    How long does it take to increase humidity in my home when using an enthalpic heat exchanger?

    An enthalpic heat exchanger does not generate humidity – it maximizes the transfer of humidity from exhaust air into fresh supply air. If you previously used a standard exchanger, not only the air but also the building structure (walls, ceilings, floors) and porous materials became dry. This means it may take some time for humidity levels to recover, so patience is necessary.

    Every enthalpic exchanger we supply is fully functional and improvement is guaranteed. We recommend keeping natural humidity sources (plants, cooking, drying clothes). If you use humidifiers, continue using them until the humidity rises to a comfortable level with the enthalpic exchanger, after which they can be reduced.

    Can I speed up the return of humidity?

    Yes. Unlike a standard exchanger, an enthalpic heat exchanger transfers part of the humidity back into the fresh air. This process is gradual, but you can speed it up by adding humidity – either naturally (plants, drying clothes, washing floors) or with humidifiers. Once the humidity has returned to a stable, optimal level, additional humidification can be reduced.

    Can an enthalpic heat exchanger increase humidity above optimal levels?

    No, an enthalpic heat exchanger does not generate humidity by itself. It only transfers part of the moisture from the exhaust air back into the fresh supply air. If humidity in your home is too high, the cause lies elsewhere (e.g., insufficient ventilation, drying clothes indoors without venting, or residual construction moisture). The enthalpic exchanger helps balance humidity and prevents extreme fluctuations.

    How does an enthalpic heat exchanger work?

    An enthalpic heat exchanger works on the principle of counterflow air streams. During ventilation, two separate airflows meet inside – the warm, humid exhaust air from indoors and the cold fresh air from outside. A special membrane transfers both heat and water vapor from the exhaust air to the incoming fresh air without mixing the two streams. This way, fresh air enters the home with a more comfortable temperature and humidity, improving comfort while saving energy.

    I don’t know how to attach the sealing tape to the exchanger.

    The sealing tape must be applied around the perimeter of the exchanger, so that when inserted it presses firmly against the unit walls and prevents false air from being drawn in. The surface of the exchanger must be dry and clean before application. Always apply the tape straight, without gaps or folds, to ensure proper sealing.
