Frequency inverter for exhaust air treatment

Reduce energy costs

Frequency inverters for motors in the exhaust air treatment of metal recycling pay off. Energy savings of more than 50 % can be achieved here. This is because the energy consumption of applications such as pumps and fans depends heavily on the speed of the motor. If this is reduced by 20%, for example, energy costs can be halved. And this is also necessary due to high electricity prices and stricter environmental guidelines of the EU. The precise control of motor speed also improves the operating performance of the fans in exhaust air treatment. Even in low-load operation, power consumption is reduced by up to 60 percent. Precise control of the air flow ensures efficient filtration and wind separation is also optimized. More energy efficiency is provided by the catch function (windmill function) of our frequency inverters for both ventilation and suction. For example, a fan that is switched off is rotating then the inverter reads the speed of the motor before activating it. It then switches to the drive at the same speed to prevent an abrupt start, which would consume a lot of power and possibly cause a failure.

Your solution for efficient exhaust air treatment with frequency inverters

Get the best possible combination of efficiency and precise control

Overseeing air filtration processes in metal recycling depends on four factors: maximum energy efficiency, fast speed control, simple commissioning and maximum flexibility.
These requirements are met by the frequency inverters of the FR-F800 series, which has been specifically optimised for motors in pumps, fans and compressors, and has many innovative features.

Increase efficiency with optimisation algorithm

At the core of inverters from the FR F800 series lies an advanced PID controller, which can manage fans, pumps, and compressors without requiring an external controller. This integrated approach simplifies the system, reduces complexity, and ensures more reliable performance.

The frequency inverters also have special functions that further increase efficiency: the specially developed AOEC (Advanced Optimum Excitation Control) optimization algorithm, for example, enables maximum energy savings even for loads that require a high torque to accelerate or decelerate.

By taking over external controller tasks and maximising energy savings through smart algorithms, exhaust air treatment applications in metal recycling plants can become more efficient, operating cost can be reduced which results in a lower environmental impact.

Experience the benefits of intelligent standby power optimisation

Similar to the start and stop function in motor vehicles, the FR F800 series drives can switch all unused circuits to standby mode to reduce energy consumption so that only 24 V control voltage needs to be applied to maintain control. A restart takes place within one second, so there is no impact on system availability. 

This feature offers considerable energy savings, particularly in applications where the system does not need to operate continuously. The savings can be easily monitored, either online or directly on the device’s display.
