For more efficient cooling of server racks

The AirBooster 2 units from STULZ are deployed in the raised floor systems directly in front of the server rack in just a few simple steps. For cooling the server cabinet, they utilize the same air conduction system from the air conditioners to the racks and are controlled exactly in line with cooling needs. Fast, simple and reliable.

All details about AirBooster 2

Airflow management solutions from STULZ

Server racks deployed in a data center feature different heat loads according to the application. In this era of server virtualization and cloud technologies, changing utilization is the requirement that has to be addressed.

This results in an oversupply or undersupply of air to your servers, which can lead to increased operating costs or even superheating followed by server failure.

Airflow solutions from STULZ are installed in the raised floor systems between server racks and air conditioning systems and are thus able to make use of the air conduction of air conditioning systems. Assuming the airflow in the raised floor is sufficient, the units supply the IT exactly with the required amount of cooling. Integrated sensors ensure that cold air requirements are automatically determined and the necessary airflow is provided. Fast, simple and reliable.

AirBooster 2 – for targeted hot spot cooling

Configurable air conduction fins

As the AirBooster 2 features manually configurable air conduction fins, this enables pinpoint cooling of hot spots where they occur. The fins are precisely directed towards target locations that require increased cooling. This concentrated airflow goes to work on the hot spots, reducing overall hot spot problems. This generates optimum supply air conditions without any complex installations or enclosures.

Airflow in two zones

The air stream of the AirBooster 2 units can be directed at 2 zones per server rack. Depending on the utilization of the server, the manually adjustable air conduction fins can be used to steer the air conduction towards the areas with the heaviest load.

Pinpoint cooling of your server racks

The units feature a speed-controlled EC fan, a controller and multiple temperature sensors. These sensors, which are attached to the server at different heights, measure the server inlet temperature. The controller controls the fan speed depending on the measured temperature values and a configurable setpoint.

If the server inlet temperature should rise, the fan speed is increased in order to ensure sufficient cooling of the servers.
