3C3® Aisle Containment system is a customizable, row-specific thermal solution that divides cold and hot air pathways within a data center. This separation occurs directly at the source, whichenhances airflow control, resulting in better cooling performance and consistency. By containing thermal zones at the row level, the system boosts cooling effectiveness and reliability, making it suitable for both targeted zones and entire data center installations. Doors are manually opened and closes automatic with the help of gas spring that prevents doors from being accidentally left open.
