Harvest season puts motor loads to work.
Make sure your electrical system is working efficiently with RONK Power Factor Correction Capacitors

Harvest season can put heavy demand on motor-driven equipment.

From grain dryers and conveyors to pumps, fans, and other agricultural loads, electrical efficiency matters when equipment is working long hours. RONK Power Factor Correction Capacitors are designed to help improve power factor, reduce reactive power demand, support motor performance, and make better use of available electrical system capacity.

When the season gets busy, efficiency matters.

Meter-Rite Double-Throw Switches
Harvest Season Power Support

Harvest season brings long days, full schedules, and plenty of equipment depending on reliable power.

RONK Meter-Rite Double-Throw Switches provide a dependable way to transfer between utility power and an alternate power source, such as a generator. For farms, shops, barns, outbuildings, and rural applications, having a safe transfer solution in place can help keep important work moving when power interruptions happen.

When the season is busy, backup power switching matters.

Rotoverter
Harvest depends on more than the combine.

Harvest season does not stop at the field edge.

Once crops start coming in, grain handling, drying, pumping, and other motor-driven equipment all need dependable power. The Rotoverter from RONK helps provide three phase power from a single phase source for agricultural operations where three phase utility service is not available.

From grain dryers and elevators to pumps and fertilizer operations, Rotoverter helps support the equipment that keeps harvest moving.

Add-A-Phase
Power for motor-driven agricultural equipment

Harvest season can put several pieces of equipment to work at the same time.

RONK Add-A-Phase converters help provide three phase power from a single phase source for demanding agricultural and industrial motor applications. For operations running pumps, conveyors, compressors, processing equipment, or other motor-driven loads, Add-A-Phase can help make existing service work harder when the season gets busy.

When the work stacks up, reliable power matters.
