The KoldLok® 3″ Extended raised floor grommet is designed to seal a variety of existing perimeter openings, with the added flexibility of modification for large and unique openings. Based on measurements at multiple data centres, between 50% – 80% of conditioned air is not reaching the air intake of IT equipment due to unsealed flooring openings. This lost air, known as bypass airflow, contributes to IT equipment hot spots, cooling unit inefficiencies and increasing infrastructure costs. By sealing cable cut-outs with KoldLok® raised floor grommets you can address this bypass airflow, so drastically improving the cooling capacity within the data centre and preventing the detrimental effects bypass airflow has.
Designed to seal a wide variety of existing and new openings. Simple modification creates the flexibility to seal large and unique openings such as those found under PDUs. Based on measurements at multiple data centres, 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. KoldLok® products specifically address bypass airflow and its detrimental effects on data centre cooling.
