Overview

Your IT equipment is generating more heat than ever and the cost to cool that equipment is increasing. According to The Uptime Institute, Inc.® electricity consumed by IT equipment is the primary driver of data center operating costs. Based on measurements at multiple data centers, 50 - 80% of valuable conditioned air is not reaching the air intake of IT equipment due to unsealed cable openings. This lost air, known as bypass airflow, contributes to equipment hot spots, cooling unit inefficiencies, and increasing operating costs. The fastest and easiest way to save money is to seal your cable openings.

The KoldLok Grommet is a superior sealing solution that increases current cooling unit capacity, mitigates equipment heat loads, and raises static pressure under the raised floor to improve cool air delivery through perforated tiles or floor grates.
