48 Optidrives are used to control water pumps in the cooling systems on six continuous casting lines in the Beltrame Group foundry in Italy. Optidrive Plus 3GV and Optidrive Plus VTC , with its innovative energy saving features, were specified in a range of sizes up to 22kW.
Innovative energy saving features
Optidrive Plus 3GV uses 3GV technology to deliver 200% torque down to 0.0Hz, allowing this unique open loop product to be used without any feedback device in many traditional closed loop applications. Designed specifically for fan and pump applications the Optidrive VTC maximises energy saving with its sleep mode feature and an automatic energy optimiser function, which reduces the motor voltage to match the load.
The Optidrive’s were supplied to Beltrame by Invertek Drives Sales partner in Italy, Siei Peterlongo electric S.p.A.
