Subzero Aisle Containment

Data center cooling represents up to 50% of overall energy consumption.

An enormous amount of energy is used every day to maintain an acceptable intake temperature to the IT equipment. In recent years, there has been no greater positive impact on the cooling of data centers than the introduction of containment. The energy savings alone has saved hundreds of millions of dollars and has greatly decreased data centers’ carbon footprint. Data center containment has virtually changed the way IT facilities are designed and operated by fully separating cold supply from hot equipment exhaust air.


What is Data Center Containment?

Data center containment fully separates the cold supply airflow from the hot equipment exhaust air. This simple separation creates a uniform and predictable supply temperature to the intake of IT equipment as well as a warmer, drier return air to the AC coil.

Hot aisle and cold aisle containment is a primary way leading businesses today help reduce the use of energy and optimize their equipment’s performance within their data center. Adopting a cold and/or hot aisle containment solution increases air efficiency, translating to increased up-times, longer hardware life and valuable energy savings.


What Kind of Data Center Containment is Best?

The question most asked when it comes to data center containment is “what should I do —rack-based, hot aisle, or cold aisle containment?” The choice depends on the facility design.

Research has continuously proved that there is improved energy efficiency through the consistent separation of cold and hot air in data centers. There are several factors to be considered when determining which air to contain: obstructions, room design, space, budget, etc.
