Reliability & ease of commissioning

05 July 2021

US MIXER manufacturer, MXD Process, has switched to Invertek Drives variable frequency drives (VFD) for use on its electric motor products thanks to their reliability and ease of commissioning.

MXD Process was having quality and supply issues with its previous VFD supplier, which was impacting on its own customers. It wanted to make the installation and commissioning of its own products easier. Reliability of the drives was also crucial, particularly important for their customers.
The company worked with Smith Automation, one of Invertek Drives USA’s Sales Reps, to identify a solution using the Optidrive E3 and Optidrive P2 range of drives.

The varying size of its mixers, from small lab stirrers to industrial mixing tanks, meant a range of VFD frame sizes and power ratings would be needed to integrate with them. The range of operating environments also meant IP66 / NEMA 4X enclosures were needed,  while the range of liquids mixed, varying in consistency and fluidity, necessitates varying torque and speed.
The company uses a range of Optidrive E3 IP66 / NEMA 4X models ranging in motor power ratings between 0.37kW/0.5HP, through to 22kW/30HP. For its larger industrial mixers, it uses the Optidrive P2 Series up to 250HP.
