Remote Monitoring of Critical VFDs and Drives

Variable Frequency Drives (VFD) are often used on critical applications in remote locations. Examples of remote and critical VFD applications would be oil and gas pipelines, water treatment and pumping, and oil production. Remote monitoring of these units can be of paramount importance.


Pipeline Medium Voltage VFD Specifications Overview

We’re seeing increased inquiries regarding pipeline VFD specifications for pipeline VFD applications. The following is a general overview that may prove helpful. We cover Siemens, Allen Bradly, Yaskawa, Toshiba and Nidec (Ansaldo).

Medium Voltage VFDs in E Houses

The cost of a medium voltage VFD project involves more than just the medium voltage variable frequency drive (VFD). Putting the drive in an E House is often a viable solution.

Happy Thanksgiving

Thanksgiving as a business practice

A young man from Korea recently taught a training class at our Georgia facility. At dinner that evening we asked him about the Thanksgiving holiday, and what he knew about it. He knew almost nothing about that, but then said, “tell me about this black Friday.” He even went so far as to say, that he’d like to delay his return so he could participate.
