Raised Floor Airflow Management by Koldlok®

Buy Air Flow Management Now

A study conducted by Upsite Technologies determined that up to 60% of cooled air does not reach IT equipment air intakes. Unsealed openings in raised flooring causes bypass airflow that contributes to hot spots and cooling inefficiencies. The Koldlok raised floor airflow management products are designed to significantly reduce bypass airflow issues and improve cool air delivery through perforated tiles and floor grates.

Sealing raised floor openings will, in turn, save you money!


Brush Style Grommets

Designed to seal openings prior to communications cable or power cable installation. The Split Integral Grommets allow tiles to be moved without capturing cables.
