43 Simovert Masterdrive drives from 0.75 kW to 700 kW 

Client expectation

A manufacturer of heat-laminated steel drums based in Germany wished to back up one of its production lines. Indeed, the electrical installation of the latter, which processes the manufacture of drums with a 98% pure alloy destined for top range automobiles, had not been updated since its first commissioning, in other words for more than 15 years. Within this context, it was imperative to back up the line drivers in order to extend the life of our client’s installation over the next 10 years.

DV GROUP Solution

Satisfied with our quality of service during a previous emergency intervention on a 630 kW principal reinjection feed, our client entrusted us with the preventive repair of 43 Simovert Masterdrive drives from 0.75 kW to 700 kW.

So, over 8 weeks, the experts were mobilised onsite in Germany to process the products and meet the schedule imposed by our client.
