Liquid Rheostats

Liquid rheostats have been proven to be a low-cost alternative to variable-speed drives in starting- and continuous-duty applications for electric motors. Whatever you need in the way of liquid rheostats, HECO will ask the right questions, then provide the one you need to do the job right.

We manufacture, recondition, maintain, and repair liquid rheostats. Reconditioning is performed in our shop, while preventative maintenance (including cleaning) and high-quality repairs can be performed in our facility or yours.

HECO can service any brand, or manufacture a custom solution. We also sell, refurbish, and supply the AC induction-wound rotor motors that liquid rheostats drive, offering a complete package to meet your needs.
