State-of-the-art. Specially developed.
Measurably efficient.
Renowned clients trust in our products.














Frequency inverters enable precise control of the speed of fan motors, resulting in improved air circulation and regulation. By adapting the speed to the actual requirements of the system, you can reduce energy consumption and extend the service life of your fans at the same time.
Our frequency inverters offer a wide range of functions, including smooth start-up sequences, load balancing and automatic fault detection. This ensures that your fan systems work efficiently and reliably.
In the event of a fire, a safety function in emergency mode prevents the frequency converter from switching off and bypasses its self-protection. Instead, it ensures that the fan continues to operate regardless of control signals, warnings or alarms. Emergency mode contributes significantly to safety in the event of a fire and facilitates the evacuation of the building.
With our many years of experience and expertise, we can help you select the right frequency inverter for your requirements. Our dedicated team will support you in integrating the system into your existing installation and ensure smooth operation.
