U4X Hybrid system
The U4X hybrid system is a multifunctional radiant ceiling system and is ideal for meeting the increasing demands of modern buildings. A special feature of the U4X is inclusion of the building mass through direct control of the concrete ceiling. This results in a mass storage capacity in addition to the usual water and air cooling capacity. This can significantly reduce operating costs and CO2 emissions.
Thanks to its closed room design, the U4X radiant ceiling module delivers good sound absorption values, particularly in the low frequency range.
The U4X radiant ceiling system is particularly suitable for offices, conference suites, hotels, schools and other commercial applications. It not only ensures comfort, but also promotes productivity and the wellbeing of employees and customers.
