Metal solutions for data centers and IT infrastructure
IT systems must be reliably cooled and protected from external influences. Perforated sheets have been the technically proven solution for this for years:
they ensure maximum air circulation, high stability, and a clean, professional appearance in data center operations.
Graepel combines perforation technology, sheet metal processing, and surface finishing to create server cabinet components that perfectly blend cooling, functionality, and design. Our components support data center efficiency and offer customization options for various rack and cabinet designs.
Graepel Percus enables the precise transfer of digital image data into high-quality perforated metal images. By carefully varying the hole sizes and spacing, a technically defined grid is created that reproduces images, graphics, or logos with great detail on metal surfaces.
Graepel ventilation grilles provide optimal cooling performance and protection in vehicles and machinery, with up to 80% open area.
“As digitalization advances, so does the need for high-performance server infrastructures with efficient cooling. An often underestimated but crucial factor here is air circulation within server and data centers. Cooling via perforated doors—some with a perforation rate of over 85%—enables optimal ventilation, and the various door designs make a significant contribution to the stability and efficiency of the overall system.
At Graepel, we combine our manufacturing expertise with a deep understanding of functional requirements and work with our customers to develop customized solutions that harmonize cooling, stability, and design."
