Variable-Speed Motor Controller

When changing reservoir condition are problem, look to ODI's variable speed motor controller (VSMC) for the solution.

Built for any type of environment, from desert heat and dust to freezing cold and rain, ODI's VSMC give consistent, year-round dependable service. A simple adjustment of the frequency setting varies flow rate and pump discharge pressure to match your changing reservoir conditions, eliminating costly system change-outs over the life of the well.
