A Depair SA patent to modernise ventilation systems

Domotech Magazine has published an article on DEPAIR SA team’s patented innovation, which makes it simple to modernise existing ventilation systems.

Many ventilation installations still rely on old asynchronous motors that are energy-hungry and costly to maintain. Until now, modernising them was complex: complete replacement of the motors, wiring and control system… often requiring heavy investment.

Thanks to a patented electronic unit, developed by Patrick Savioz and the DEPAIR SA team in Sierre, it is now possible to replace these old motors with modern, efficient EC motors without changing the existing wiring or control system.

The main benefits

• Up to 70% energy savings on certain installations
• Less noise and less heat dissipation
• Improved indoor comfort
• Compliance with current energy control requirements (SIA 384/2, BMS, CO₂ sensors, etc.)
• A step-by-step approach: modernise gradually, without replacing everything at once

This solution is ideal for modernising older installations in apartment buildings, public buildings, industrial sites and co-owned properties.

We thank Domotech Magazine for this excellent showcase of our innovation.
