Summer Demand Is Already Here...
Efficiency Matters.
RONK Power Factor Correction Capacitors

As temperatures rise, electrical systems often work harder.

RONK Power Factor Correction Capacitors are designed to help improve electrical efficiency, support motor performance, reduce reactive power demand, and help facilities get more from their existing electrical systems.

For operations running motor-driven equipment through the heat of summer, now is a good time to take a closer look at power factor.

Roto-Con CP
Are you ready for when the rain stops?

A wet start to the season can change fast, and when crops still need water, reliable irrigation matters. The Roto-Con CP is specifically designed for center-pivot irrigation systems, helping operations get the three phase power they need from a single phase source.

When the forecast changes, make sure your pivot is ready to keep water moving.
