Energy-efficient motor technology

• 11 and 15 kW drive in accordance with energy efficiency class IE5
• Efficiency of up to 96 %
• Smoother running and more thrust when agitating thanks to optimized blade geometry of the wide-blade propeller and hub
• Increased thrust with lower power requirement
• Infinitely variable speed control due to a tuned frequency converter for optimum stirring results under different operating conditions
• Approved up to 65°C substrate temperature and 40 m immersion depth

The new large propeller mixer series is the ideal solution for all applications
where a high circulation capacity is required. Designed for high dry matter contents when used in
fermenters and secondary fermenters for optimum substrate mixing and flow maintenance. With
powerful motors from our own motor factory and the large propeller diameter, this agitator
propeller diameter, this agitator series offers the optimum solution for your operation.
Thanks to the combination of low drive power, enormous thrust and greatly increased
circulation capacity paired with the use of a frequency inverter in the GTWSL 156-E and
GTWSL 206-E, we call these agitators the most economical agitators in the world.
