A proven drive, superior for the gas compression market

SPOC drives have a well-earned reputation for productivity and durability in artificial lift applications. The same engineering, the same productivity, the same proven durability are hallmarks of our products for midstream applications as well.


We make drives for a number of uses in the gas compression market, all of which are proven to help you run more efficiently and reliably. CVD features built-in automation and logic control and is engineered for 240V, 480V, 600V low-voltage motor drives. Control and protection are preconfigured, and our service techs are available for field support.

Our drives can help you save on electrical costs (with an additional benefit of improving your productivity) by eliminating wasted energy and reducing maintenance and downtime on your compressor.

CVD drives serve a wide variety of compression applications:

  • Vapor Recovery Units (VRUs)
  • Gas Lift
  • Injection/Reinjection
  • Wellhead Recovery
  • Refrigeration Compression
  • Gathering/Boosting

With the CVD drive, we make it easy to access your historical and production data. Fault indications are in simple English, so any of your people can know exactly what is going on when an issue occurs.

  • Data logging with USB
  • Single touch USB
  • Color-coded status
  • Parameter change history

4,160v vs 480v — The math is clear. If you are using a medium voltage drive to control a motor of 1,000 HP or less, you should ask yourself “Why?”

WiseGuy: The easiest, most detailed VFD interface available

Smart. Intuitive. Easy. That’s what customers are saying about WiseGuy, the operator interface that comes with every SPOC drive package. WiseGuy speaks your language, so that any operator can master it in minutes. It’s just that easy.

Knowledge is power in the hands of your operators, and the WiseGuy gives you live trending history, date & time stamp, data logging, single touch USB downloads, and much more in the industry’s easiest-to-use, smart and intuitive drive package.

Service is always a standard feature

Service is always a standard feature

Upstream, midstream, the oilfield is a difficult, often brutal place. But we understand the pressure to keep your pumps running, no matter the application, no matter the conditions. Our drives are made for extreme conditions—they are engineered and built to run through the heat, the cold, the dust. That said, in the oilfield everything breaks, sooner or later.

If one of our drives goes down, our technical team is available 24/7

Our service team will have you back up and running in hours, not weeks. As one of our customers said, “In the oilfield, there is no tomorrow. Only today.” And that is the belief we live by.

We also offer customers DriveShield — the most comprehensive extended warranty in the entire industry. With DriveShield, you are protected at all times, even against lightning strikes.

Our low-harmonic drives keep you running reliably, efficiently and in compliance

Harmonic drive compliance becomes more critical every day. At SPOC, we focus on the entire system, providing low-harmonic drives to ensure that you continue running reliably, efficiently and in compliance of IEEE519 and EN-6100-3-2.

We manufacture every type of low harmonics drive, using the latest technology available.  Everything we do is tailored to your needs.

In general, we recommend the Active Front End VFD  for minimizing harmonics in fields incorporating variable speed drives. This technology is electronically based, not magnetically based. It meets the IEEE519 under every scenario and all loading conditions, regardless of voltage imbalance or source impedance. It is so advanced it can actually correct for low-voltage conditions from marginal systems and correct power factor within the electrical system, saving you money.
