The ContraFlo cabinet turns airflow upside down to offer an alternative to hot aisle containment or chimney designs. Using a raised floor plenum as the return plenum, ContraFlo can simplify the requirements needed to successfully isolate hot exhaust air.

Using any flooded room approach the cool air is supplied to the IT equipment through a typical perforated front cabinet door. ContraFlo then uses a solid roof and rear doors to channel the exhaust air down through a high volume airflow panel into the raised floor plenum, isolating it from the cool air in the room. Pressure differential monitoring is used at the rack level to maintain accurate airflow delivery at all times, ensuring no more energy than required is used for cooling the space.

Advantage Over Other Hot Air Containment Solutions

Hot air containment requires additional components and considerations to realize the benefits. ContraFlo reduces costs and eliminates the obstructions created by chimneys or aisle containment systems and ductwork to air handling equipment simplifying the distribution of other services.

Reverse Flow Cabinet

Using a reverse flow cabinet allows the exhaust air to funnel into a raised floor return plenum. This allows for any cabinet configuration and eliminates overhead containment structures for more cable distribution space. The raised floor return plenum also provides the perfect pathway for power distribution helping to segregate power and data cables.

Slab Design
Slab designs limit the flexibility and adaptability of a data center. By using aisle or chimney containment on a slab wire & cable service distribution becomes challenging due to the many overhead obstructions.

Reverse Flow Cabinet
Using a reverse flow cabinet with a raised floor offers many advantages over a slab design.  A raised floor return plenum and reverse flow cabinet is more cost effective than a cabinet with hot air containment solution. In addition, raised floors simplify the maintenance and distribution of other services.
