For information on the specifications for each KoldLok® Brush Grommet that we offer and to help to choose the proper one to fit your needs, view our data sheet:
Designed to seal a variety of existing raised floor tile cutouts and allow flexibility of removing tiles without capturing cables. Large and XLarge Grommets allow for larger sealing capacities. 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. 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 center cooling.
