Technical expertise. Personal service.

About us

At Händle & Korte, you work directly with technical specialists. Our team is entirely technical and supports you personally – from initial advice to day-to-day operations.

We are independent of return targets set by external investors. This lets us focus on what matters to our customers: reliable technology, the right solutions and long-term support.

Technology

We operate our infrastructure primarily in four data centres in Düsseldorf. All sites have strictly controlled access, power systems with UPS, diesel generators and at least N+1 redundancy, and redundant cooling systems. Early fire detection and fire suppression systems are installed at every site.

All four sites are close by, allowing our technicians to respond quickly and provide on-site support when needed.
