Based on measurements taken at multiple data centers, on average 60% of valuable conditioned air is not reaching the air intake of IT equipment due to unsealed floor openings. This lost air, known as bypass airflow, contributes to IT equipment hotspots, cooling unit inefficiencies and increasing infrastructure costs. The KoldLok Surface Mount Raised Floor Grommet is specifically designed to address bypass airflow and its detrimental effects on data center cooling. The ability of the KoldLok Surface Mount Raised Floor Grommet to cover a large tile area makes this product particularly useful for sealing a variety of perimeter openings. It is engineered and designed to seal a variety of existing raised floor tile cutouts and allow flexibility of removing tiles without capturing cables. This product is available in 3 model sizes (original, large and extra large).
