Why the Transition to Rehlko
In 2024, Kohler Energy rebranded globally as Rehlko, reflecting a stronger focus on long-term power innovation and sustainability.
According to the official announcement, the name Rehlko derives from the letters of Kohler and represents the company’s enduring values of reliability, resolve, reinvention, and resilience.
The rebrand unifies Kohler’s power systems, engines, and energy operations under a single forward-looking identity — designed to support evolving demands for efficiency, lower emissions, and global energy resilience.
What This Means for Equipment Owners
- Engines remain the same in design, displacement, and model coding.
- Part numbers, service intervals, and accessories remain unchanged.
- Rehlko-branded components fit directly onto existing Kohler engines.
- Documentation can reference either brand name interchangeably.
For owners, operators, and distributors, the transition is entirely seamless — only the logo has changed.
