Data Center Raised Floor Grommet

RLE Grommets Provide Immediate Airflow Improvements, ROI

Plugging holes is one of the easiest ways to improve airflow and efficiency in any raised floor environment. If air can escape through holes in a raised floor you limit the effectiveness of containment and decrease your facility’s cooling efficiency.

Filling cutouts in raised floors with grommets will result in improved airflow and efficiency. Filling cutouts with Split Integral Floor Grommets from RLE Technologies will take airflow improvements to the next level!

What Set’s RLE’s Grommets Apart?

RLE’s patent-pending foam grommet seals better and prevents air from passing through the grommet significantly better than the leading competitor’s grommet. How much better? When tested against the leading competitor, 50% LESS air escaped the RLE grommets. Drop in an RLE grommet and see an immediate improvement in air loss.

RLE Grommets feature:
