Upsite Technologies, Inc. has released a KoldLok raised floor grommet designed for 600-millimeter raised floors typically found outside of the United States.

KoldLok grommets are like custom cable cutouts that include interlocking bristles so that cables can go through but cold air can’t escape. Data centers use them to reduce bypass airflow, which wastes air-conditioning air meant to cool servers. Upsite, formerly Triton Technology Systems, Inc., is the maker of KoldLok and is connected to The Uptime Institute, the group that formed data center tier levels.

The new grommets are available now.
