Customer Testimonial

  • Game Changer

    We found the transition to Freelance went very smoothly. The product and support have been exceptional. It has opened windows into our plant that we never had. We’ve been very satisfied with the ABB system.
    Instrument & Controls Lead - Gas Plant

  • Nice software

    Sales, installation, troubleshooting… Winn-Marion has become our one-stop shopping partner.
    Production Superintendent - Gas Production Company

  • You can't beat the price

    Winn Marion's retrofit eliminated a whole lot of linkage, probably 6 joints, and wherever you have a joint you have problems. Right now both the turbines are running the best I have ever seen in my 30 years of maintaining them.

  • Our BFW turbine retrofit, performed by Winn-Marion, couldn’t have gone any smoother or been more successful.
