KoldLok® raised floor grommets are designed to significantly improve energy efficiency in data centers with climate‑controlled raised floors. By sealing cable openings, they prevent valuable cold air from escaping through unsealed cutouts — a common cause of cooling losses and reduced airflow at the front of server racks.

Unsealed cable penetrations allow conditioned air to leak into the wrong areas, typically behind the racks. This reduces the cold air volume available in the cold aisle and forces cooling systems to work harder, increasing energy consumption. KoldLok® grommets eliminate these leakage points and support the cooling system by ensuring that cold air reaches the equipment where it is needed most.

The patented KoldLok® design uses high‑quality brush elements and a specialized sealing structure that allows cables to pass through while preventing air from escaping. This improves overall cooling efficiency, stabilizes rack inlet temperatures, and reduces operating costs for the data center’s cooling infrastructure.

By integrating KoldLok® grommets into your airflow management strategy, you enhance energy efficiency, improve system availability, and create a more stable thermal environment for your IT equipment.
