BSK NOTUS HV residential heat recovery units offer high thermal insulation with next-generation EPP bodies, up to 90% thermal efficiency, advanced control options with WiFi and mobile application, and easy installation thanks to its lightweight structure.

The NOTUS HV model offers air flow up to 375m3/h, ans combining vertical/horizontal and right/left type devices into a single unit with interchangeable air ducts. Our units are plug-and-play, equipped with G4 filters, automatic bypass damper, temperature and humidity sensors as standard. Additional sensors and functional features can be added with optional expansion modules.

BSK Zephyr decentralized heat recovery device is a ventilation solution designed for rooms without an existing ventilation infrastructure. It is easy to install, has very low noise and energy consumption, and comes with built-in wireless connection features.

BSK Zephyr can recover heat by using a 2-way fan  heating and cooling of the ceramic heat exchanger inside. The device operates on a cycle that extracts and supplies air in periods of 70 seconds. While the air is extracted out from the room, the ceramic heat exchanger will be heated, when the air flow direction is reversed and fresh air from outside is supplied to the room, thanks to the heat stored in the ceramic core, it will be blown inside in a conditioned manner. BSK Zephyr, whose power consumption does not exceed a few watts and can reach 90% thermal efficiency, also allows you to save energy while meeting your ventilation needs. You can connect multiple devices to each other via wi-fi, and you can control your devices with the included IR remote.

BSK Scholar high efficiency heat recovery devices are specially designed for classrooms, meeting rooms or offices without existing ventilation systems. Our devices provide 100% fresh air to the area and exhausting the dirty air. Fresh air is passed through a double filter system which get rids of dust, pollen, spores and other harmful particles.

Thanks to the highly efficiency counter flow heat exchanger inside, the heat energy of the exhausted air is used to heat up the fresh air taken from outside. No energy is wasted for this passive heating process. In this way, you can significantly decrease your heating costs against conventional ventilation methods.
