Revolutionise your ventilation without touching the wiring

The patent presents an innovative solution that makes it easy to replace an asynchronous motor with an EC motor (electronically commutated) in a ventilation system, without any modification to the existing wiring or to the building’s control system (MCR).

This retrofit approach remains compatible with existing electrical panels and integrates seamlessly into the current infrastructure, greatly simplifying implementation for HVAC professionals. The EC motor, far more efficient, consumes significantly less energy for the same airflow — savings of up to 70% — while reducing heat dissipation and fan operating noise. In addition, EC technology offers finer control over fan speed, allowing more precise airflow adjustment without altering the existing control configuration.

Ultimately, the invention delivers a significant improvement in the energy and acoustic performance of ventilation systems, while easing the transition to modern, high-efficiency technology without additional rewiring costs or changes to existing control systems.
