Control Techniques drives are powering a significant mixed-waste recycling facility in the UK.

Avelair, which designs and manufactures variable speed air and gas compressors, has utilised Control Techniques’ Unidrive M600 and Commander C200 drives in a unique project responsible for processing large quantities of mixed waste and converting it to aggregates and refuse-derived fuel.

The system employs a full compressed air system, including four 110 kW rotary screw air compressors, air treatment equipment, compressor management and the complete pipework system. In doing so, the new facility deposits mixed wastes via a full suite of automated processes.

David Wood, Managing Director of Avelair, said: “This is one of our largest UK compressed air installations. Our team designed and manufactured four variable speed 110 kW rotary screw air compressors for the recycling plant at our UK facility.

“Control Techniques’ Commander C200 and Unidrive M600 power the four units. The onsite management controller is programmed to switch lead compressors at intervals, to share the load and improve efficiencies. The drives are robust and reliable, and are so simple to install and pair with the motor. The programming equips us with advanced options, specific to the application, if we need it. The Safe Torque Off (STO) and onboard PLC are all further advantages, while the compactness of the drives keeps the installation neat and clean.

“As members of the ‘Made in Britain’ campaign it’s fantastic when we find a British company we can rely on and trust. Control Techniques has supported us in many designs over the years and we look forward to continuing this relationship into the future.”
