Easy to use, no harmful emissions and energy savings of 10-40% (most customers report approximately 20% on average), the IronHorse literally pays for itself by reducing energy costs. With near unity power factor, elimination of inrush currents and associated peak demand charges, and a reduction of utility kwh usage, the IronHorse drive payback is quick. Traditional across-the-line starters or Pump Panels will “never reduce” your operating cost or pay for themselves, but it’s guaranteed with the IronHorse Drive!
Experience has taught our customers that the bigger savings can be through decreased mechanical wear on pumping units, virtual elimination of rod separations, and reduction of transmission stress of over 50%. One user reported a 75% reduction of rig workovers in a large field simply by switching to our variable frequency drive technology from the standard across-the-line starter pump panels.
Programming and operating the IronHorse drive is easy and intuitive. Using oil field units of measure like “strokes per minute,” as well as standard fault names such as “field kill” or “vibration switch,” the IronHorse was designed to be used on beam pumps. Built-in production calculations assist in evaluating wells. The IronHorse is also available in single phase input, eliminating the need for costly, problematic phase converters and the associated over-sizing of components or motors. Additionally, those traditional methods cost you more on your O&M budget dollars due to the high electrical losses that accompany them.
Smart. Intuitive. Easy. That’s what customers are saying about the WiseGuy DL operator interface that is optional on IronHorse Series Drive packages. If you know industry terminology like “Daily Strokes,” “Run Time History” or “Pump Offs” then you can operate the WiseGuy DL. It’s that easy. Knowledge is power in the hands of your pumpers and the WiseGuy DL give 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.
Using the WiseGuy DL, the most recent 30 day production history and up to the last 97 pump off events are graphically viewable and downloadable.
Sensorless Pump Off Control
IronHorse drives, with the addition of SPOC (Sensorless Pump Off Controller) software, give you the ability to run your beam pumps and slow them down automatically if enough fluid is available, at pump off rather than stopping the motor. Utilizing the self-teaching mode, the IronHorse with SPOC software will run the pump at optimal speed for the wells inflow rate and maximize production. This will extend the life of the equipment and in most cases, increase production, getting you the maximum return on your investment. In the event your well does not produce enough inflow to keep producing a slower speed, then you simply set the SPOC software up to stop like traditional pump off controllers. What’s more, there are no costly sensors or load cells to install on the pumping unit that can be damaged, which would rend the unit inoperable.
