High Density Cooling

Precision air conditioning units for accurate cooling of high heat loads

STULZ offers a wide range of solutions and systems for direct rack cooling in order to precisely and efficiently cool high heat loads and hot spots on racks. These solutions provide maximum, reliable and accurate cooling with minimum footprint. So your application always operates in the optimum range, even at maximum workloads.


CyberRow is the innovative air-conditioning system in which the air distribution takes a new direction – horizontal. The individual units are carefully integrated in the rows of server racks, greatly improving air distribution and taking cooling directly to the heat load.

Product information


The CyberRack Active Rear Door is a heat exchanger door with EC fans for installing on the rear door of server racks. The server rack door is swapped for the CyberRack Active Rear Door, which transforms the rack into a cooled server rack that no longer discharges any heat load in the data center.
