The Whole range of Data Center cooling solutions

Stulz is a world wide leader in suppling the whole spectrum of data center cooling products and services at the highest quality level.

CyberAir - Stand-Alone solutions for High-End Applications


The CyberAir 3 precision air-conditioning system with Indirect Free Cooling and Direct Free Cooling conditions the air in data centers and equipment rooms with a heat load of over 20 kilowatts up to 90% more economically than conventional compressor cooling systems.

Along with the exacting requirements for data center air conditioning, the need for exceptional ideas is also growing, such as how to regulate temperatures to within a degree at the lowest possible cost. To reach this goal, our engineers strive daily to enhance the energy efficiency of our precision air-conditioning solutions. The CyberAir 3 shows how serious we are: The result is a system with completely reworked air conduction, optimised in many details that work together in perfect harmony.

Compact Plus – Direct-Expansion Air-Conditioning for Data Centers

For minimal investment, the Compact Plus DX precision air-conditioning system ensures the availability of your sensitive technology in large rooms with a heat load from 18 up to 104 kilowatts.

The Compact Plus DX units offer excellent performance and operational reliability for little money. This electronically controlled system uses cooling compressors and works on the direct evaporator principle (Direct Expansion - DX). The system is available as a single- or dual-circuit system.

Easy installation, simple maintenance from the front, and compact design make our Compact Plus units a superior air-conditioning controller in equipment rooms. .

MiniSpace and MiniSpace EC – Compact precision for server rooms


The MiniSpace precision air-conditioning system from STULZ cools small servers and equipment rooms with a heat load of up to 28 kilowatts. With MiniSpace, you can keep your computer systems cool much more precisely, economically, reliably and durably than with conventional comfort air-conditioning systems. The system works either via a cooling compressor with air or liquid cooling (DX system), or especially economically with chilled water (CW system). The units require very little floor space, and their compact size means they can be installed in existing server rooms with no problem. The microprocessor regulates the temperature and humidity precisely to the last degree.

CyberRow - Intelligent Air Flow Control for more Efficiency in Rack Cooling

CyberRow is an advanced precision A/C unit, which is tailormade for the targeted cooling of racks. In the CyberRow, innovative air conduction has been enhanced by state-of-the-art technology, which enhances the performance, flexibility and efficiency. Fluctuating server rack loads, space restrictions, lack of a raised floor, existing server technology - these are some of the tricky situations in everyday practice that the CyberRow has been specially developed to deal with.

CyberRow is a standalone A/C unit and is installed and operated independently from the rack. This complete separation of the rack and the A/C unit increases reliability and provides greater freedom for designing the layout in the data center.

CyberCool Chillers


Water conveys heat 3500 times better than air. Our chilled water generator from the CyberCool product line was developed for maximum reliability in data centers and in the field of medicine: whatever the local temperature profile and with maximum efficiency – 24/7, 365 days a year.

CyberHandler Air-conditioning unit


STULZ CyberHandler is designed with proven STULZ cooling technology for stringent demands of data centers and can be mounted on top of a building or ducted to the side of a building.

CyberHandler is a centralized cooling solution designed specifically to free up white space in the data center.


CyberCon - Cooling for Containerized Data Centers


The STULZ CyberCon outdoor modular container system is designed for conditioning the air in a prefabricated data center. This modular cooling solution is ideal for rapid deployment and reduced construction time.

CyberCon can be mounted on top of a containerized computer room.

Air flow management for Data Centers with closed-circuit air conditioning


Air flow system solutions from the STULZ AirBooster series are installed directly in front of the server rack, in the raised floor. Integrated sensors ensure that cold air requirements are automatically determined, and exactly the right air flow rate is provided based on the required temperature. All elements of STULZ air flow solutions utilise the same air conduction system, from the air conditioners to the racks, and are controlled exactly in line with cooling requirements.
