Generac Liquid-Cooled & Industrial Series Generator Installation in Ohio

Liquid-cooled engines for long run times and large loads, for businesses, facilities and large homes across Ohio, installed by our own licensed team.

Liquid-Cooled

Why Choose Generac Liquid-Cooled Generators?

For a commercial or industrial customer, a generator failure can halt operations, compromise refrigerated inventory and expose a facility to liability. Liquid-cooled engines carry larger loads for longer, which is why large homes, businesses and facilities choose them.

Higher Output

The Protector Series runs from 25kW to 150kW on natural gas or propane and from 15kW to 50kW on diesel, past the top of the air-cooled line.

The Whole Building

The generator senses the outage, starts on its own and powers the entire home or business, large equipment and sensitive electronics included.

For Sites That Cannot Go Dark

Industrial diesel units suit high-kW sites where code requires fuel stored on site. Generator One serves residential, commercial and industrial customers from Mentor.
