Ensuring there’s no wasted cooling is vital. Accurate control of the airflow through KoldLok Grommets allows us to consider energy-savings strategies such as increasing CRAC set points.

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.
