Blanking panels are a crucial yet often overlooked component in data centre management, playing a vital role in optimising airflow and enhancing energy efficiency. These panels are designed to fill the empty spaces in server racks, preventing the recirculation of hot air into the cold aisle, which can otherwise lead to hotspots and reduced cooling efficiency. By directing cool air precisely to where it’s needed and ensuring that hot air is properly expelled, blanking panels help maintain optimal operating temperatures, reduce the workload on cooling systems, and ultimately lower energy costs. Available in various sizes and materials, blanking panels are easy to install and offer a cost-effective solution for improving data centre performance. Regular use and proper installation of blanking panels not only contribute to a more efficient and reliable data centre but also extend the lifespan of critical IT equipment.
