Engineered Products That Work

SubZero engineering, drawing from its knowledge gained through hundreds of Computational Fluid Dynamics studies, has developed products that facilitate necessary airflow changes in the data center.

Data center airflow problems come from three basic areas:

• Uneven subfloor air pressure
• Bypass air flow
• Cold and Hot air mixture

You can be confidant that when you install our products they have been fully tested in real-world data centers.

The Cube

The SubZero Cube is the finest cable cut out cover on the market. Unlike other covers made of brushes or less pliable material the Cube is designed to fill in around cables and both the underside and top of the raised floor. This ensures a complete seal.
Simply squeeze…put into place and release.

The soft cube fills in the opening and around the cables. Installs in seconds… even under equipment. The cube is completely non-flammable.

Subfloor Air Velocity Adjustor

Subfloor air pressure is not consistent. This is because of subfloor air speed. The greater the speed the less the pressure (see Bernoulli Principle). Low pressure means a low ‘throw rate’ or volume of air (CFM) into the computer room. This can have a devastating effect on cooling air in both sufficient volume and height at the computer rack intake.

SubZero velocity adjustors slow subfloor air down and thus balance subfloor air pressure. This way you can get sufficient cooling air in any place in the data center.

RackHat Ceiling Partition System

The Sub Zero RackHat is a Ceiling Partition System that saves cooling energy and increases cooling capacity. At the core of the system is the separation of cold intake air from hot exhaust air. For years data center engineers have seen the value of hot and cold air separation. This knowledge moved managers to migrate rack rows into hot and cold aisles. In spite of this, hot exhaust air often does not have a clear path back to the CRAC unit without rolling over into the cold intake aisle. The RackHat creates an ESD free barrier that hot air must go around, thus preventing it from working its way into the cold aisle.

A study by Lawrence Berkeley National Laboratory demonstrated that data centers that install partitions to more precisely direct the airflow can save energy on both air conditioning and fan systems – 15% and 67% respectively.
