Imagine a state-of-the-art recycling facility that processes 120,000 tonnes of mixed waste per year, from which it produces aggregates and refuse-derived fuel. Avelair won the prestigious contract to design a full compressed air system, including four 110kW rotary screw air compressors, air treatment equipment, compressor management, and the complete pipework system, for a new recycling facility designed to do just that.
The new site deposits mixed wastes via processes that are mainly automated and consist of shredding, optical sorting, trommels, ballistic separators, magnets, and baling.
To guarantee the plant's efficiency, Avelair required a drive to power the compressors, allowing the ramp-up of the motor speed to produce the compressed air to meet onsite demand.
David Wood, Managing Director of Aveliar, said: "this is one of our largest UK compressed air installations. Our team designed and manufactured four variable speed 110kW rotary screw air compressors for the recycling plant at our facility in Bury St Edmunds."
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 between the four compressors, establishing a super-efficient process.
The variable speed air compressors employ Control Techniques' inbuilt inverter technology on the main high-efficiency motor and fan motors, ensuring maximum energy savings.Button Component Impressed? Contact us for your automation needs
The winning combination of Commander C200 and Unidrive M600 delivered significant benefits to the finished product. David Wood said: "As members of the Made in Britain campaign it's fantastic when we find a British manufacturer we can rely on and trust. Control Techniques has supported us in many designs over the years. For this project, it listened to what we wanted to achieve and helped us to engineer the chosen inverter into the compressor."
"The drives are robust and reliable, and 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, not to mention the compactness of the drives, which keep the installation neat and clean."
