Pentair Technical Products’ Hoffman brand PROLINE containment system is designed to segregate cold (intake) and hot (exhaust) air. Consisting of aisle doors, ceiling panels, and chimney stacks, the new containment system can be used for hot or cold air containment, preventing the hot and cold air from mixing, which can lead to poor cooling and wasted energy. By increasing cooling efficiency, the system manages a higher thermal density without requiring additional cooling units, which can result in extra capital costs and expensive equipment downtime. Available for use on raised or non-raised floors in small to large data centers, the PROLINE Containment System is designed for use with the company’s line of PROLINE cabinets and can be modified to work with alternative enclosure brands.
