Turnkey system solutions from Frerk
We develop, project and deliver complete backup power supply solutions — from needs analysis through engineering, manufacturing and testing to installation, commissioning and long-term service. A continuous process, a minimum of interfaces, maximum support.
Our products and services
Four areas of expertise that cover all requirements for modern backup and safety power supplies. In combination, optimized, reliable and turnkey units and systems of the highest quality are produced.
Generator sets
Complete backup power solution in low and medium voltage. Manufactured in modern production halls on 21,000 m². Gensets, emergency power systems (EPS) and uninterruptible power supply (UPS) systems for worldwide use.
Test field
Full load testing in the test field with inductive load devices for gas and diesel-powered systems. From June 2026, 19 test benches will be available.
System integration
Manufacturer-independent integration of motors, generators, batteries and all other relevant components. The selection of proven OEMs is carried out with precise coordination to find a perfect system solution.
Installation variants
Mobile gensets, container solutions, building installations, roof installations, underground installations or modular power plants — we create the optimal variant for your requirements.
Turnkey solutions
All services from a single source
In the Frerk range of services, each area is managed by specialized and experienced teams, coordinated internally and implemented worldwide. At our headquarters in Schweringen, Lower Saxony, this creates a turnkey replacement power supply that meets individual and highest requirements — everything from a single source.
Individual special solutions for all requirements
Standard gensets reach their limits when there are special technical, spatial or regulatory requirements for the power supply. Frerk is your partner for tailor-made special solutions.
Needs analysis & design
Detailed recording of technical, local and regulatory frameworks.
Transposition
Implementation of complex special solutions through project planning, coordination and quality management
focusing.
Generator sets
Gensets, emergency power systems (EPS) and uninterruptible power supply (UPS)-systems in low and medium voltage: From standard gensets to tailor-made system solutions implemented on 21,000 m² of production and test space. For critical infrastructures, data centers and many other industries and applications worldwide.
Installation variants
Mobile gensets, container solutions, building installations, roof installations, underground installations or modular power plants — every project requires a specific installation variant. We design the optimal solution for your spatial and technical requirements and coordinate the entire installation on site.
System integration
Manufacturer-independent integration of motors, generators, batteries and all other components from proven global OEMs — precisely tailored to an optimized system solution. Maximum integration strength through experience, long-term partnerships and customer-specific design. UPS- systems for uninterrupted power supply for critical infrastructures.
Test field
If required, full load testing of gas and diesel-powered systems with inductive load devices on 19 in-house test benches. Gensets and emergency power systems are tested under real conditions before they are delivered.
Diverse areas of application
Frerk gensets secure the power supply worldwide and in a wide variety of applications. Our solutions ensure reliability where electricity is required decentrally or power outages and fluctuations cannot be tolerated.
Critical infrastructure
Uninterruptible power supply (UPS)-systems and emergency power systems (EPS) so that system-relevant facilities are maintained.
Data centers
Reliable backup power supply without interruption for data centers worldwide.
Immediate, secure and maximum availability guaranteed
