STULZ has expanded its portfolio of data centre cooling solutions with the introduction of the new CyberRack SideCooler, developed specifically for high-density IT environments, edge computing applications and micro data centres.
Cooling for high-density IT environments
The CyberRack SideCooler is a water-cooled rack-based cooling solution designed to be installed directly between server racks or within a micro data centre. By removing heat directly at its source, the system reduces heat transfer into the surrounding data centre environment while maintaining stable operating conditions even under high thermal loads.
The growing demand for high-performance computing (HPC), artificial intelligence (AI) and machine learning applications has significantly increased server power densities and cooling requirements. According to STULZ, the CyberRack SideCooler has been developed specifically to address these challenges by combining high cooling capacity with a minimal footprint.
Flexible and energy-efficient operation
The solution is compatible with server racks from a wide range of manufacturers and is available in both open-loop and closed-loop configurations. The system utilizes water-cooled heat exchangers and energy-efficient EC fans, which automatically adjust their operation according to the actual thermal load.
This intelligent control approach enables efficient cooling performance while optimizing energy consumption. By delivering cooling directly at rack level, the system supports improved thermal management and increased overall energy efficiency within the data centre.

Designed for easy installation and maintenance
The CyberRack SideCooler has been engineered with ease of installation and serviceability in mind. Its compact design helps maximize the use of available floor space, while front and rear service access points simplify maintenance procedures.
Hot-swappable fans allow components to be replaced without interrupting system operation, helping to minimize downtime and maintain continuous availability in mission-critical environments.
Optimized for edge and micro data centres
In closed-loop applications, the CyberRack SideCooler prevents warm return air from being discharged into the data centre environment, reducing the need for traditional hot-aisle and cold-aisle containment systems. This simplifies data centre design while contributing to higher cooling efficiency and lower energy consumption.
The solution is particularly suited to environments where limited space, high power density and demanding reliability requirements call for efficient and energy-conscious cooling. CyberRack SideCooler enables operators to meet the growing demands of modern edge computing and micro data centre deployments while ensuring reliable 24/7 operation.
