SplitLok™ Integral Raised Floor Grommet

Name: SplitLok™ Integral Raised Floor Grommet
SKU: 4040

Designed to seal openings in new or existing raised floor cutouts used for communications or power cabling. Based on measurements at multiple data centers, on average 48% of valuable conditioned air is not reaching the air intake of IT equipment due to unsealed floor openings. This lost air, known as bypass airflow, contributes to IT equipment hot spots, cooling unit inefficiencies, and increasing infrastructure costs. KoldLok® products specifically address bypass airflow and its detrimental effects on data center cooling.

After having hands-on experience with nearly every available product on the market, HotLok is by far the superior choice. Not only does it create the best seal, but its universal mounting system and finger grips make it the easiest to use and reuse.

We have looked and looked for a solution like KoldLok. If KoldLok had been around ten years ago, we probably would not have needed to add a cooling unit back then. It improves the efficiency of our cooling system a great deal.

The 4 R's of Airflow Management™

Managing cooling in your data center is a holistic process. We've developed a methodology which we call the 4R's of Airflow Management which addresses the specific needs of aisle containment, floor containment, hot aisle containment and then monitoring of the facility. Each part of the 4R's addresses particular needs which build upon each other and enhance the effectiveness of cooling optimization efforts.
