Designed to seal a wide variety of existing and new openings, the ability of the KoldLok Extended Raised Floor Grommet to cover the full length of a tile, makes it a particularly useful tool for sealing perimeter openings. Simple modification creates the flexibility to seal large and unique openings such as those found under PDUs. Based on measurements 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. The lost air, known as bypass airflow, contributes to IT equipment hotspots, cooling unit inefficiencies and increasing infrastructure costs. KoldLok Extended Raised Floor Grommets are specifically designed to address bypass airflow and its detrimental effects on data center cooling. This product is available in both a 3 inch and 6 inch length.
