The mounting bracket enables easy and quick installation of the recuperator on the wall or ceiling without the need for additional brackets and hangers. Integrated handles integrated with the casing ensure safe transportation of the device.
The dry siphon supplied with the device allows for trouble-free and maintenance-free operation of the condensate drainage system throughout the year, eliminating the need to refill the water seal during the summer to ensure the system’s tightness.

Smart Mode

Innovative control system for reQnet heat recovery units

Energy savings

Energy savings through optimization of the heat recovery unit's operation based on current conditions in the building.

Automatic operation

Without the need for involving household members in the daily operation of the ventilation system and manual changes in its performance.

Higher air quality

24/7 in-house operation to improve the comfort and health of the entire family.

Control the heat recovery unit with your phone

In each central unit, we have placed a Wi-Fi module that connects to your home internet and allows convenient control of the device via the phone by any family member – even on the couch, even on the other side of the world!

The reQnet application provides full control of your heat recovery unit, without the need to install additional wall controllers. It allows you to control various operating modes of the device and enables remote viewing of current working parameters.

Advanced solutions in the IN-OUT cassette

reQnet heat recovery units come with a modern hi-tech automation system as standard equipment. It controls the operation of all device parameters using advanced algorithms.

The reQnet automation board has been equipped with several additional connectors allowing cooperation with a wide range of peripheral devices.

We have also developed an innovative IN-OUT cassette that allows you to remove and insert the automation board into the device with just one move!!

Connect to the cloud and remote service

Don’t get left behind and update your heat recovery unit’s software independently with cloud work. You can also provide remote access to your device for the installer or service technician!

Stay up-to-date and maximize your heat recovery unit’s capabilities. Cloud connection allows for automatic software updates and remote access for the service technician!

DOUBLE FILTRATIONInnovative double anti-smog filtration system in reQnet heat recovery units
Stops over 95% of PM10 smog particles

A two-stage filtration system using two pleated filters, including an F9 precision filter, guarantees the capture of over 80% of the smallest PM1 smog particles, which are less than 1 micrometer in size. These particles are the most dangerous to our bodies because they can penetrate directly into the bloodstream and spread to internal organs

Original filters included in the price of replacements!

COUNTERFLOW HEAT EXCHANGERSThe heat exchanger is the heart of a heat recovery unit

In reQnet ventilation units, it is possible to use two different types of heat exchangers: a standard counterflow heat exchanger HRV or an enthalpic counterflow ERV.

The used counterflow heat exchangers with cross-partitions allow air exchange and do not allow mixing of air. They recover thermal energy, and in the case of an enthalpic heat exchanger also humidity.

Exchangers of this type do not contain moving parts, which makes them very durable and easy to keep clean.

* In the case of reQ V and H, due to the high flow, it is recommended to connect the drain to the sewer.

Slim design


The longitudinal arrangement of the connection ducts allowed for the creation of a narrow housing, which does not take up much space in technical rooms.


Thanks to the unique flat design with a heat exchanger placed transversely, the reQ V. heat recovery unit only protrudes from the wall by 47 cm! This allows for convenient installation of the heat recovery unit in narrow rooms or garages.

The reQ V. series unit is mainly intended for wall mounting in technical rooms. The original stainless steel mounting bracket, which is included as standard equipment, allows for hanging it on the wall quickly and securely.

In the case of floor mounting, dedicated feet are also available, allowing for easy installation of the siphon.
