Total System Integration.
Total System Integration.
Everything works together. Just as it should.
Rehlko designs modular components that work together flawlessly. Then, we use these building blocks to engineer a system custom-made for your space. After rigorous factory testing and expert installation, every part will work harmoniously with the entire system—for decades.
Rehlko supports mission-critical infrastructure during an outage.

Remote Annunciator
A monitoring system that provides a user-friendly display of the generator's status.

Automatic Transfer Switch
This product automatically switches a building’s power source from the main grid to a backup generator during an outage. When normal power is restored, the ATS reconnects to the main supply to ensure continuous power without manual intervention.

Paralleling Switchgear
Paralleling switchgear synchronizes multiple generators to work together, sharing the load and ensuring a reliable power supply. It automatically manages the power distribution, balancing the load between sources and allowing seamless transitions.

Generators
Rehlko generators come in a range of sizes and can operate in parallel with multiple units. For added protection, Rehlko offers durable enclosures and user-friendly controls with advanced network communications for seamless operation.
Cleaner energy solutions.
At Rehlko, we're committed to advancing sustainable power without compromising performance. From renewable fuels to transparent environmental reporting, our cleaner energy solutions help reduce your carbon footprint while maintaining mission-critical reliability.

Hydrotreated Vegetable Oil (HVO)
HVO fuel provides up to 90% renewable energy for your backup generator, ensuring both mission-critical reliability and a commitment to a sustainable future.

Conscious Care
Our Conscious Care program delivers advanced solutions through more sustainable procedures that minimize your environmental impact - without compromising the reliability of your generator.

Environmental Product Declaration (EPD)
Rehlko became the first in the industry to publish an EPD for the KD Series™ K175 generator, in accordance with ISO 14025 standards and in the form of a PEP Ecopassport®. This document provides full transparency into the generator’s environmental footprint.
