Control Techniques inverter drive technology provides smooth, reliable power for improved wash and extraction, reduced energy and water consumption and enhanced customer experience.

Schulthess, the leading Swiss supplier of washing equipment, has selected Control Techniques’ Commander C300 inverter drives for its latest product development, helping to meet its demands for quality and performance, while also offering a technological advantage and satisfying regulatory requirements.

Inverter drives are crucial components in the design of the laundry solution as proprietary inverter drive technology provides smooth, reliable power for better wash and extraction, reduces energy and water consumption, and improves the customer experience.

The Swiss and UK team at Control Techniques worked closely with Schulthess’ R&D department to provide the best match for its needs. Commander C300, with the built-in laundry specific software, proved to be the right solution.

Commander C300 can detect imbalances caused by laundry becoming tangled into large lumps and initiate a tumbling sequence to untangle the load. Thanks to this feature the wash cycle is much smoother and the machine life is extended as there is less stress to the mechanical parts. 

The on-board PLC has allowed the joint teams to further expand the laundry specific capabilities while also reducing the size of the installation as an external controller was no longer required.  

Commander C300 is built to cope with harsh environments. Control Techniques are so confident in its durability it is supplied with a free 5-year warranty, yet another valued benefit to guarantee the quality of the Schulthess machinery.

Mr. Remo Bucher, Engineering Manager, Schulthess, concludes, “Since switching to Commander C300, we have been able to simplify the system design. For example, we no longer need an imbalance sensor. Imbalance detection and broken belt detection are all built-in the PLC. Commander C’s motor control performance is outstanding, and it has greatly improved our testability and troubleshooting compared to the previous drive.

Throughout this project, we have had excellent support from the Control Technique teams in the UK and Switzerland and it’s been a great working partnership. We will most certainly use Control Techniques’ inverters for our future projects.”
