RECUBOX® ERV 03/100 is the smallest enthalpic RECUBOX® for flow rates up to 140 m³/h . With a height of only 160 mm , it is ideal for low ceilings and small spaces. It offers heat transfer efficiency of up to 95% and humidity efficiency of up to 75%. Variability of nozzles and a 12-year warranty on the tightness of the casing .
The enthalpy RECUBOX® ERV 03/100 is the smallest enthalpy RECUBOX® in our range. It is a compact, extremely durable and hygienically clean jacketed enthalpy recovery exchanger designed for modern modular air recovery.
Unlike a conventional heat recovery exchanger, the enthalpy variant can transfer not only heat but also some of the moisture from the exhaust air back into the fresh air supplied. The result is a more comfortable indoor environment, especially in winter, when the air inside is often too dry.
Thanks to its extremely small dimensions of 441 × 441 × 160 mm, it is an ideal solution for low ceilings, small apartments, tiny house projects, toilets, sanitary facilities, technical rooms with limited space and decentralized HVAC systems.
The height of only 160 mm allows installation even where classic heat recovery units simply cannot be used.
Main parameters:
The enthalpy exchanger does not create humidity, but it can return some of the humidity from the exhaust air back into the interior. This helps to alleviate excessive drying of the indoor air during the heating season.
In normal operation, the humidity in the interior does not increase immediately. The enthalpy exchanger works gradually - the humidity is returned continuously and the resulting effect depends on the specific house, the ventilation mode, the outdoor temperature, the humidity of the exhaust air and the absorbency of the building materials.
The practical result is a more pleasant indoor climate, less feeling of dry air, higher living comfort while maintaining hygienic air exchange.
Custom production in the Czech Republic. RECUBOXY® is manufactured completely in the Czech Republic according to the exact requirements of customers. We use high-quality polypropylene materials from SIMONA AG and professional hot gas welding technology on Leister AG equipment.

Each RECUBOX® is created as an honestly processed technical product - with an emphasis on precision, tightness, long service life and the possibility of adapting to a specific installation.
 |
Maximum hygiene The exchanger and the entire unit can be easily cleaned by rinsing with clean water. The exchangers used have ILH Berlin hygiene certification. |
 |
Mechanical sealing without adhesives The exchanger is sealed with a groove gasket without the use of adhesives or tapes. The gasket can be easily replaced if necessary. |
 |
Without screws, rivets or glue RECUBOX® is made from a single type of material using hot gas welding technology. The result is strong, tight and long-lasting joints. |
 |
Extremely wide size range We can design a suitable RECUBOX® even for very limited technical spaces while maintaining the required volumetric air flow. |
 |
Compatibility with various types of exchangers RECUBOXY® can be fitted with exchangers from RECUTECH, ZERN ENGINEERING, AIRWOODS, CORE, HOLTOP and other compatible types. |
 |
Wide range of performances We produce RECUBOXY® in the range from approximately 50 m³/h to several thousand m³/h . |
 |
Maximum variability The location of the inlet and outlet ports can be adapted to the specific installation. Thanks to custom manufacturing, we can to address even atypical requirements. |
 |
Left and right versions All variants are available in left and right versions. Condensate drainage is provided by a 1/2" connection in two positions. |
 |
Easy installation The unit is ready for assembly using threaded rods and simple installation in a technical space, suspended ceiling or separate technological part of the building. |
The enthalpic RECUBOX® ERV 03/100 can be equipped with three types of enthalpic counterflow exchangers.
Each of the exchangers offers a different technology, design and price/performance ratio. This allows RECUBOX® to be adapted to the specific requirements of the project – from an economical solution to the cutting-edge METALPIC technology.
The exchanger is selected during the order process.
|

RECUTECH RFK+16-100-HF-28 – METALPIC enthalpy A top-of-the-line enthalpy exchanger from the Czech manufacturer RECUTECH with modern METALPIC technology. This is the most advanced option for customers who want the maximum technological level, low pressure losses and long-term durability.
Recommended choice for the most demanding applications where emphasis is placed on efficiency, comfort and quality of workmanship. |
Thanks to their robust construction, high quality and hygienic safety, our RECUBOXY® are part of a number of CTU projects, including the unique SAWER system, which UCEEB is developing for obtaining drinking water from the air.
We provide a superior 12-year warranty on the tightness of the RECUBOX® unit casing.
The casing is made of high-quality polypropylene and joined using hot gas welding technology, which creates homogeneous, strong and long-term stable joints without the risk of degradation .
Unlike constructions using Whether glued joints, sealing tapes or combinations of different materials, RECUBOX® retains its airtightness and mechanical resistance even after many years of operation .
 |
Possibility of installing inspection doors The exchanger is a fixed part of the RECUBOX® structure, but its cleaning and flushing with water can be very easily done through the inspection door (openings). This makes system maintenance extremely easy even after many years of operation. |
 |
RECUBOX® can be ordered in several insulation options:
In the double-walled version, the insulation is hermetically sealed between two shells . In addition to the insulation itself, this creates an additional robust 5mm polypropylene shell , which further increases strength, durability and overall quality of the design. The result is an extremely durable and long-term stable construction suitable even for demanding operation. |

RECUBOX® ERV 03/100 is designed for use with external duct fans.
For optimal performance, we recommend fans with similar parameters as:
 |
Possibility to order AFL EC CONSTANT FLOW fans The RECUBOX® ERV 03/100 can also be supplied with a pipe jacket for installation with AFL EC CONSTANT FLOW fans. AFL EC CONSTANT FLOW fans for RECUBOX® A huge advantage of CONSTANT FLOW technology is the ability of fans to automatically respond to changes in pressure losses in the system and adjust the speed to maintain a stable airflow over the long term. The fans are also very suitable for smart homes – thanks to 0-10 control They can be easily connected to, for example, Loxone, Home Assistant and other intelligent systems. |
The regulation and control of RECUBOX® can be solved in many ways depending on the type of fans used and the requirements of the specific installation.
The big advantage of a modular system is that you are not tied to one specific control. The control can be designed simply for undemanding applications, or as part of a smart home or advanced ventilation system.
| AC fans |
Simple and economical control for light applications. For example, control using a 0/1 - on / off - style timer can be used for AC fans. The operation of fans can also be regulated using triac controllers . |
| EC fans |
Modern, economical and very well adjustable solution. If you use EC fans, their performance can be continuously controlled using a DC 0–10 V signal. To control EC fans, you can use, for example, our RekupeX REX EC controller: REX EC – controller for heat recovery systems with EC fans You can also use another EC controller or a direct connection to a smart home, such as Loxone or Home Assistant . |
Thanks to the modular RECUBOX® concept, you can choose exactly the level of control your project needs – from simple on and off to fully integrated smart home control.
