RECUBOX® HRV 03/100 is the smallest 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 efficiency up to 95% , custom-made in the Czech Republic, variable necks and a 12-year warranty on casing tightness .
RECUBOX® HRV 03/100 is the smallest RECUBOX® in our range. A compact, extremely durable and hygienically clean jacketed heat recovery exchanger designed for modern modular air recovery.
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:
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 a carefully crafted technical product - with an emphasis on precision, tightness, long service life and the ability to adapt 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. |
 |
|
 |
Without screws, rivets and glues 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, 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 nozzles can be adapted to the specific installation. Thanks to custom manufacturing, we can also solve 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. |
RECUBOX® HRV 03/100 can be equipped with two types of highly efficient counter-flow exchangers.
Both variants offer high recovery efficiency.efficiency of up to 95% while maintaining low pressure losses and very quiet operation.
The exchanger is selected during the order process.
|
RECUTECH RSF+16-100-HF-32 Modern Czech counterflow heat exchanger from the manufacturer RECUTECH with HPS fins and very low pressure losses.
The ideal solution for comfortable and very quiet air recovery. |
|
ZERN ENGINEERING HU-HD EX6 366/100 High-quality counterflow heat exchanger from ZERN ENGINEERING with robust construction and proven technology.
A proven solution for economical and reliable heat recovery. |
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 forextracting 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 structures using 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 for demanding operation. |

The variant selection takes place during the ordering process.
Dimensions are given without insulation. In the case of insulated versions of 30 mm or 50 mm, it is necessary to allow for an increase in dimensions of 70 mm and 110 mm (double-skinned).
If rubber internal insulation is chosen, the dimensions of the RECUBOX® will not change.
If it is necessary to adjust the dimensions, for example due to larger connection sockets or specific installation requirements, we will inform you after ordering.

Do not hesitate to contact us with your specific request. We manufacture RECUBOXY® to order and in many cases we can adjust the orientation or location of the nozzles to suit the specific installation. |
RECUBOX® HRV 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 fansrong> The RECUBOX® HRV RSX-P - 03/100 can also be supplied with a pipe jacket for installation of 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 V 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.
