maincubes FRA04 is a flagship hyperscale data center strategically located in Dietzenbach, just south of central Frankfurt, within one of Europe’s most important digital infrastructure and cloud connectivity hubs. Delivering 40 MW of critical IT capacity, FRA04 is the company’s largest single-site development and is purpose-built to support the demanding requirements of global hyperscale cloud providers, artificial intelligence (AI), high-performance computing (HPC), financial institutions, content platforms, and large digital enterprises. Designed for next-generation compute environments, the facility supports high-density deployments with flexible direct-to-chip liquid cooling architectures capable of accommodating rack densities exceeding 40 kW, making it ideal for GPU-intensive AI training and machine learning applications. Powered entirely by 100% certified renewable electricity, FRA04 combines operational resilience with industry-leading sustainability, helping customers meet ambitious environmental and carbon reduction goals. The campus incorporates highly redundant electrical and mechanical infrastructure, advanced energy-efficient cooling systems, and waste heat recovery technology that exports excess thermal energy to local municipal district heating networks, contributing to a circular energy economy while achieving an ultra-low operational Power Usage Effectiveness (PUE). Fully aligned with EU Taxonomy sustainability standards, FRA04 also provides carrier-neutral connectivity with diverse fiber routes to Frankfurt’s major internet exchanges, cloud availability zones, and international network gateways. Supported by advanced physical security, continuous infrastructure monitoring, and scalable expansion capabilities, maincubes FRA04 serves as a future-ready platform for cloud growth, AI innovation, and sustainable digital transformation across Germany and Europe.
