FRERK & DEIF: More safety in the backup power supply
FRERK Aggregatebau GmbH relies on a broad network of proven, long-standing suppliers committed to quality.
As a system integrator and OEM packager, FRERK Aggregatebau GmbH relies on a broad network of proven, long-standing suppliers committed to quality.
This includes DEIF (Danish Electro Instrument Factory). Since 1933, the company has stood for safe and reliable control technology and systems for decentralized energy generation. For decades, we have shared the common goal of continuously and consistently improving products and solutions with this family-run and independent company.
Through ongoing collaboration, ideas and technological innovations in control systems could be extensively tested and adapted directly in FRERK's own test field on emergency power systems for data centers, critical infrastructure, decentralized energy generation, and many other applications.
The personal exchange with Burkhard Klinkert made the collaboration particularly valuable. Due to his imminent retirement, he and his successor, Zeljko Miulovic, Senior Sales Manager at DEIF GmbH, paid us a final visit in Schweringen.
With sincere thanks for the excellent support and enormous expertise, we wish you a wonderful and well-deserved retirement and look forward to continuing our collaboration with Mr. Miulovic.
