Bentec is committed to manufacturing safe and reliable systems that provide all of the power and control electronics needed to power up all of the electric units on a drilling rig. The Bentec Top Drive Control Room provides a high-quality standalone solution for powering up each electrically driven top drive.

In addition to the PLC-controlled VFD unit, the Bentec Top Drive Control Room contains all the components required for operating a top drive. These include an MCC for auxiliary drives, a step down transformer, a harmonic filter, and a range of other controls. All of the top drive’s parameters are accessible via an HMI inside the Top Drive Control Room. The driller’s controls are located on the drill floor and serve to control all functions of the top drive. The plugged connections located outside the container significantly reduce the rig move time.

The VFD unit, a Bentec-own development, is a perfectly aligned and highly reliable system. Featuring a redundant air conditioning system designed by Bentec, it ensures that operation is possible in any environmental conditions.

On request, a remote access client can be installed in the Top Drive Control Room. In the event of failure, a Bentec service technician can log into the system for troubleshooting purposes.

Bentec combines all of the experience it has gained from more than 30 years of developing and enhancing power control rooms to offer a safe, reliable and user-friendly Top Drive Control Room.
