RECUBOXES® are manufactured entirely in the Czech Republic.
as custom production based on the exact specifications provided by our customers.
High quality is guaranteed by the use of the highest quality materials from the German manufacturer SIMONA AG in combination with processing using Swiss Leister AG equipment.
We present you a smart solution for a heat recovery system with endless variability of the resulting ventilation system (unlike heat recovery units, fans are placed
separately into the pipeline, as well as other additional accessories. Thanks to this, the system guarantees a long service life with easy replacement of individual components, unlimited expandability and system upgrades at a minimum price)

REMOVING THE HEAT EXCHANGER FROM THE RECUBOX is very simple, literally in one go. |
|
MAXIMUM HYGIENE is guaranteed thanks to the possibility of removing the exchanger and washing both the exchanger itself and the entire unit. RECUBOX material certified for food storage and use in healthcare |

THE EXCHANGER SEALING in the RECUBOX is done by sealing into the groove without the use of adhesives or adhesive sealing, which degrades over time. This makes removing the exchanger and reinserting it completely simple. The seal can be easily replaced if necessary. |

INFORMATION ABOUT THE INSTALLED COUNTER-FLOW ENTHALPIC EXCHANGER:
The enthalpy exchanger not only transfers heat, but also air humidity. However, it has a lower heat transfer efficiency compared to a classic counter-flow exchanger.
The EX series counter-flow enthalpy recovery exchanger offers an alternative to the classic counter-flow heat exchanger in buildings that suffer from low air humidity.
The return of moisture back into the fresh air is possible thanks to the unique technology of a polymer membrane with micropores, which only allows water molecules to pass through. The membrane blocks the transfer of bacteria, mold, smoke, toxic substances or odors. Of course, heat is transferred with the highest possible efficiency through the slat wall. Thanks to the excellent design of the exchanger and high hygiene standards, the exchangers can also be used for ventilation of kitchens, toilets or laboratories with a permanent source of air pollution.
The geometry of the slats is developed to maximize the efficiency of heat and moisture transfer.
FixedThe exchanger shell is made of HPS ( high impact polystyrene).
The exchanger can be cleaned under running water with a maximum temperature of 50°C.
The exchanger must be protected from freezing.

SERVICE ACCESS AND BY-PASS DIMENSIONS | |
/cms/SERVISNI%20PRISTUP_1.png" alt="" width="299" height="215" /> |
SERVICE ACCESS - dimension E A minimum space corresponding to the length of the exchanger must be provided in front of the recubox door so that the exchanger can be removed from the recubox without any problems. E = C - 60 [mm] INTEGRATED BY-PASS - dimension F The integrated by-pass is located “behind the exchanger” and increases the recubox by 1/3 of the depth.
BY-PASS opens the fresh air bypass around the exchanger with almost zero pressure loss. Opening the BY-PASS does not close the passage through the exchanger, but thanks to the open BY-PASS, the amount of fresh air passing through the exchanger is minimized. |
