Rehlko (formerly Kohler): Engineered for Total System Performance

A Century of Power Resilience: The Kohler Legacy, The Rehlko Future

Rehlko is a new name built on one of the oldest and most respected legacies in the power generation industry. The company’s history began over a century ago when, in 1920, Kohler Co. introduced the world’s first engine-powered electric generator, the Kohler® Automatic Power and Light. For the next 100 years, Kohler built a global reputation for engineering excellence, powering historic Antarctic expeditions and providing critical power during WWII.  

In 2005, Kohler significantly expanded its global reach and technological capabilities by acquiring the French-based manufacturer SDMO Industries, becoming the world’s third-largest generator manufacturer. Building on this powerful foundation, the recent evolution from Kohler Energy to Rehlko marks a strategic shift to focus entirely on creating an energy-resilient world. Rehlko inherits Kohler’s century of engineering know-how and is positioned to lead the future of reliable and clean energy solutions.  

Rehlko Power Unit

Rehlko’s product philosophy is centered on providing a complete, factory-integrated power ecosystem where every component is designed to work together flawlessly.

The Rehlko Generator Portfolio

Rehlko is known for factory-integrated systems where the generator, transfer switch, switchgear, and controllers are built to work together.

  • Product lines: Diesel and gaseous generators. KD Series with G-Drive engines. Rehlko ATS, paralleling switchgear, and Decision-Maker® controllers.
  • Power range: From under 10 kW up to 4 MW in the KD Series.
  • Fuel options: Diesel certified for HVO, plus natural gas and LP. The company is advancing hydrogen fuel cell technology for zero-emission applications.

    What sets the KD Series apart for large facilities?

    KD Series generators use purpose-built G-Drive engines for high output and strong motor starting. They are a fit for data centers, hospitals, and campuses that need large, stable power.

    Can Rehlko Decision-Maker controllers integrate with building management systems?

    Yes. Many models offer standard protocols and I/O to tie into BMS and SCADA. We confirm features by controller version.

    Do I need Rehlko ATS and MPAC switchgear with a Rehlko generator?

    You do not have to, but single-source systems reduce integration risk. We can also integrate Rehlko generators with third-party gear when required.

    What is the typical lifespan of a used Rehlko diesel generator?

    With proper maintenance, Rehlko diesel generators are known to run for tens of thousands of hours. Many standby units have low hours and a lot of life left. Our inspection helps estimate remaining life.

    Do used Rehlko generators come with a warranty?

    Used units do not carry a new manufacturer warranty, but Generator Source offers warranty options or guarantees on select units. Ask about coverage for the specific generator you are considering.

    Can Generator Source assist with installation and ongoing maintenance for a used Rehlko generator?

    Yes. We can handle installation and connect you with our service teams for maintenance, parts, and technical support. Service locations include Austin, TX, Brighton, CO, Jacksonville, FL, and Pensacola, FL.

    How do I know the condition of a used Rehlko generator?

    Every unit receives a comprehensive 31-point inspection, including load bank testing. We share reports, photos, and often videos so you have full transparency on condition and performance.

    Are replacement parts readily available for older Rehlko generator models?

    Yes. Rehlko’s global parts and service network is a major advantage. Parts for most Rehlko engines and generator models are widely available, which supports long-term ownership.
