A New Generation of Backup Power, Built for Long-Term Value

Choosing backup power isn’t just about today’s performance. It’s about knowing your investment will hold up tomorrow, next year, and ten years from now. The new Rehlko KD Series™ 60–600 kW range is designed to deliver that kind of confidence: premium performance that pays off over the long haul.

Reliability, Proven in Testing

Every KD Series unit is built to withstand more than standard industry checks. From vibration and thermal balance to electrical safety and noise, each generator is tested until it proves itself ready for critical uptime. For customers, that means assurance that when the grid goes down, your power doesn’t.

• Vibration Testing: Built to meet ISO 8528-9 standards, our gensets are tested to prevent long-term wear and protect critical components like engine-alternator couplings.

• Thermal Performance Validation:

  • EMEA: Units are tested at ambient temperature and extrapolated to simulate operation from -20° to +50° in Celsius and -4° to 122° in Fahrenheit.

  • North America: Thermal cycling and cold start tests expose units to rapid temperature shifts, ensuring reliable ignition and stable performance in extreme climates.

• Sound Performance: Noise levels are optimized and certified to meet or exceed EU and local standards, with annual audits and acoustic testing ensuring quiet operation in sensitive environments.

• Performance Class Validation: Each unit is tested for load acceptance, voltage regulation, and startup reliability—so you know it will perform when it matters most.

Tailored Testing for Your Environment

Rehlko adapts its testing protocols to meet regional regulations and environmental challenges. KD Series units undergo:

• Shake testing to simulate seismic and transport stress (For North American installations)

• Missile and hurricane wind simulations to validate resilience in extreme weather conditions (For North American installations)

• Rain testing: to validate enclosure integrity and ensure uninterrupted operation in wet conditions

With over 100 prototypes tested and approved across our manufacturing plants, the KD Series is more than ready—it’s proven.

Support That Feels Local

Power may be global, but service is personal. Rehlko’s worldwide distributor and service network ensures customers have access to:

• Over 220 distributor partners across every continent

• Stocked Rehlko parts available within 24–48 hours

• Factory-trained technicians on-site within hours

• Rehlko Direct Service and Sales Offices in key European markets including the UK, France, Spain, and Germany.

It’s a model designed to combine scale with the responsiveness that matters on the ground.

It’s more than a service plan, it’s a partnership that powers your peace of mind.

Configured Around You

No two sites are the same. That’s why the KD Series was engineered with thousands of possible configurations.

Whether you’re powering a healthcare facility, a manufacturing facility, a commercial building, or a small business, Rehlko configures each KD Series generator to fit your exact needs.

Whether you need:

• Specific voltage and frequency settings

• Open or sound-attenuated enclosures

• Modular systems for scalability

• Advanced control panels with remote monitoring

• Compliance with local grid codes and emissions standards

Rehlko’s engineering team ensures your generator is built for your requirements—not the other way around.

Built for Long-Term ROI

Investing in backup power is about more than immediate security. The KD Series is designed to reduce total cost of ownership, provide easier access to trusted genuine parts, and extend uptime over its lifecycle. It’s value measured in years, not quarters.
