The enthalpic RECUBOX® 360 VENT-READY is ready for easy installation
top-of-the-line AFL EC fans with CONSTANTFLOW system
![]()
RECUBOXES® are manufactured entirely in the Czech Republic , as custom-made products based on precise 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 on Swiss Leister AG equipment .
RECUBOX® 360 VENT-READY is a completely unique, indestructible and hygienically clean base for the heat recovery unit , made of polypropylene with 100% smooth walls inside and out .
The cabinet is structurally prepared for the installation of AFL EC CONSTANT FLOW fans , which, thanks to intelligent regulation, maintain a constant flow rate and pressure balance of the entire system.
Thanks to their exceptional efficiency, the system can deliver up to 360 m³/h even at an external pressure of 400 Pa (after deducting exchanger and housing losses).
Inside the RECUBOX® there is an enthalpy exchanger that transfers not only heat but also moisture.
The exchanger is deliberately oversized to minimize pressure losses , which guarantees quiet and economical operation.

The fans can be installed within 15 minutes – just by inserting them into the prepared hole and tightening four screws.
All outlets and condensate drains are designed in a mirrored manner , so you only choose the mounting direction during installation .
RECUBOX® can of course also be operated with external fans of your choice.
Regulation, as with all EC fans, is quite simple – it is carried out using a DC 0–10 V signal.
This control method allows for convenient control of either:
manual regulator ,
with smart regulation RekupeX REX EC , or
by direct connection to a smart home system (e.g. Loxone) - without the need for any intermediate link .
The enthalpic RECUBOX® 360 VENT-READY is supplied as a separate cabinet without fans and controls.

Thanks to their robust construction, top quality and maximum hygienic safety, our RECUBOXES are part of a number of CTU projects, including the unique SAWER system, which UCEEB is developing for obtaining drinking water from the air.
MAIN ADVANTAGES OF RECUBOXES®: |
| 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. The exchanger is certified by ILH Berlin with a hygiene certificate and the RECUBOX material is certified for food storage and use in the healthcare sector |
| 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. |
| NO SCREWS, RIVETS OR GLUE - RECUBOX is made from one type of material using hot gas welding technology . This ensures absolutely tight joints without degradation due to aging , unlike other joints of different types of materials. |
| SIZE RANGE We basically offer RECUBOX® VENT-READY in 3 performance types, but we are able to manufacture RECUBOXes up to a volume flow of 10,000 m3/h on request. |
| RECUBOXY OPEN are designed for the complete production line of EUROVENT certified RX, RX-P and RSX-P exchangers |
| PRESSURE EQUALITY when using RECUBOX® VENT-READY with the AFL fan, pressure equalization of your entire heat recovery system is guaranteed without complicated adjustment |
style="margin-left:auto;margin-right:auto;" /> | Options for fitting the MALAPA IN03 IONIZER |
| ENDLESS VARIABILITY of placement of inlet and outlet nozzles in any dimensions |
| MIRROR USE is possible for all variants. The condensate drain is secured with a 1/2" diameter screw connection and is fitted in 2 places |
|
INSTALLATION is easy thanks to mounting holes for threaded rods |
|
LARGE AREA FILTERS for the use of any filter fabric, which is easily replaceable. The unit is basically equipped with filter fabrics of filtration class M5. |
| BY-PASS is available as a short-circuit part or integrated with preparation for manual or servo control. The diameter of the by-pass shaft is 14 mm |

| SERVICE ACCESS AND BY-PASS DIMENSIONS | |
![]() | SERVICE ACCESS - dimension E A minimum space corresponding to the size of the recubox door must be provided. the length of the exchanger so that it 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. |
