Koldlok Raised Access Floor Grommets


Improve Energy Efficiency of Server Rooms and Data Centres by preventing “Leaks” through the deployment of Koldlok raised floor grommets.

When raised access floors are deployed in combination with down flow AC systems the leakage of cold air in the wrong places will reduce the effective cooling capacity of the system. Increasing cooling capacity to compensate is expensive and wasteful of energy.

A better solution is to reclaim lost cooling capacity by sealing unmanaged openings that are wasting cold air. This will ensure air is circulated to where it is needed via correctly positioned grille floor tiles.

Typically these openings are found where cable access is required below cabinets.

The installation of specially designed raised floor brush grommets will help seal the floor and prevent leakage of air where cables are routed into equipment cabinets.

The incorporation of floor sealing systems will help:

  • Increase existing cooling unit capacity
  • Reduces the need to purchase additional cooling units
  • Improves equipment reliability and extends equipment life
  • Increases static pressure under the raised floor and improves cool air delivery through perforated tiles and floor grates
  • Facilitates cold aisle/hot aisle best practices

Workspace Technology deploys Koldlok systems within both existing and new server room solutions. Koldlok forms part of Workspace Technology’s “FlexAisle” passive airflow management technology. Further details are available on

KoldLok Configuration Options


The Integral raised-floor grommet is designed for new installations and fits into the raised-floor tiles prior to the installation of the cabinets.

Split Integral

The Split Integral raised-floor grommet is ideal for new installations on the edge of floor tiles. This raised-floor grommet is in two halves and allows the cables to be removed.


The Extended series is designed to fit and seal cut-outs against walls or, when two are used together, they can seal half a floor tile.
