Data center scheme with airflow management units

STULZ updates its product line for flexible airflow management

Elimination of hot spots and pinpoint cooling of high-density zones with no need for structural alterations to the data center

Integrated sensors ensure the required amount of cold air is determined automatically, so precisely the right airflow is always supplied. Depending on the specific volumetric airflow required, the air is supplied either purely passively via adjustable louvers, or actively via an integrated, speed-regulated EC fan.

Hamburg, 31/1/2017 – STULZ, the German specialist in data center air conditioning is updating its range for efficient airflow management. The units in the AirModulator and AirBooster series have benefited from extensive upgrades and a new design. Like the previous generation, the new AirModulator 2 and AirBooster 2 models from STULZ can be installed in the existing raised floor with the greatest of ease. There, they infinitely regulate the existing airflow and therefore ensure targeted, on-demand cooling of the individual server racks.

Typical areas of application are high-density or blade servers with a high performance density or areas with an extreme processor load. Furthermore, integrated sensors ensure the required amount of cold air is determined automatically, so precisely the right airflow is always supplied. Depending on the specific volumetric airflow required, the air is supplied either purely passively via self-regulating louver dampers or actively via fan-assisted raised floor grilles.

The "AirBooster 2" from STULZ generates an airflow of up to 4,360 m³/h via an EC fan, and can reliably discharge heat loads of more than 20 kW, to suit the permitted operating temperature of the servers. The air conduction fins in the AirBooster 2 are manually adjustable and can be aimed at two different zones. The fan speed is controlled on the basis of temperature using a mean value from three sensors in total. These can be mounted on the rack at different heights, where they record the current server inlet temperature of the supply air at all times.

The STULZ "AirModulator 2", on the other hand, manages without fan assistance, but is equipped with a motor-driven louver damper. Here too, the damper is opened and closed in line with the temperature. In addition, airflow management solutions from STULZ can also be supplied with pressure control, in order to automatically compensate pressure differences between different cold aisle zones, for example, and so ensure correct, on-demand airflows throughout the data center. The ventilation grilles of STULZ airflow management solutions are also available in a heavy duty version on request, for withstanding high mechanical loads. The heavy duty version can also bear the weight of lift trucks.
