CK Power, a St. Louis Generator Builder

CK Power is a St. Louis manufacturer, distributor, fabricator, and authorized service provider for engines and generator sets. The company traces its roots back nearly a century and is now run by the third generation of the Costello family. Its generator sets are built at its St. Louis manufacturing hub. That combination of roles is unusual. CK Power sells its own proprietary equipment directly to end users, distributes engines and power units, and builds equipment under contract for other manufacturers. The result is a company with deep engine and packaging expertise, even if its own badge is less familiar than the largest national brands.

CK Power Generators for Agriculture and Utilities

CK Power serves industries where power systems often need custom configuration rather than an off-the-shelf unit, including agriculture, healthcare, and utilities such as water districts and municipal systems. Custom design and flexible lead times are a core part of how the company operates. For a buyer, that means CK Power units in the used market can vary more from one to the next than mass-production equipment. Engine, controller, enclosure, and fuel configuration should be confirmed on each listing rather than assumed from the brand.

Why Configuration Matters on a Custom-Built Unit

With a national-brand generator, one model number usually tells you most of what you need. With a manufacturer that builds to application, the spec sheet carries more weight. Before committing to a CK Power unit, confirm four things:

• Engine make and model. This determines where you source filters, injectors, and major components for the life of the generator.
• Rating and duty. Standby and prime ratings differ on the same machine, so compare like with like.
• Controller. Confirm it supports the transfer switch, monitoring, or paralleling your site requires.
• Fuel and enclosure. Match fuel type to what is available on site, and the enclosure to the environment it will live in.

Sizing a CK Power Generator

List every load running at the same time, separate resistive from inductive, and account for the surge motors draw at startup. Our power calculators will get you a working estimate. Once you have a number, shop the matching range: 25kW – 99kW for light commercial and agricultural use, 100kW – 499kW for mid-size facilities, or 500kW – 999kW for large buildings. The shop by kW page lists every range across every brand we carry.

Buying CK Power Equipment Outright

For standby duty, buying is the clear answer, since a backup generator earns its value by being on site when the utility drops. Our used industrial generators keep the upfront cost down, and our generator financing options spread it further. Renting fits a project or temporary gap with a defined end date. Our rental division, Stag Power Rentals, handles those situations.

Testing Custom-Built CK Power Packages

Every generator we sell passes a 22-point inspection and load bank testing before shipment. On custom-configured equipment, testing under load is what confirms the package performs as a system, not only as a set of components. We have been buying and selling industrial generators for more than a decade. Every purchase is backed by our 30-day IronClad warranty. After delivery, our service team handles preventative maintenance and fuel system repair. Comparing independent American manufacturers? Taylor Power Systems generators are a close parallel, and our shop by brand page covers every manufacturer we carry.
