A highly adaptable, field-fabricated hot or cold aisle containment solution that installs over cabinets of varying sizes and works around architectural obstacles—ideal for retrofit deployments. By isolating the cold aisle, containment reduces unintended mixing of cold supply air with hot exhaust air, maintaining uniform, predictable. Armstrong aisle containment combines flexible design, strategic sourcing, and American manufacturing to deliver solutions that ensure long-term performance in a rapidly evolving digital world. Armstrong aisle containment solutions provide high-performance systems that support efficient, scalable. Beyond implementing basic measures such as sealing moisture out of the data center and improving air flow, aisle containment to prevent the mixing of hot and cold air stands out as a method that can dramatically reduce energy costs, minimize hot spots and improve the carbon footprint of data. Chatsworth Products (CPI) offers adaptable aisle containment solutions—helping you get the most from every rack and every watt. Airflow management is one of the most effective ways to improve efficiency, reduce cooling costs, and meet sustainability goals. With. Traditional open aisle data centres use perimeter PAC (precision air conditioning) or CRAC (computer room air conditioning) units to channel cold air up through a raised floor void via grilles positioned in front of the IT cabinets. These cooling systems, which are usually considered in isolation.
