MiniSpace becomes CyberAir Mini
With our MiniSpace series, we brought a system onto the global market that reliably air conditions rooms subject to high heat loads. In further developing and integrating the MiniSpace in the CyberAir series, the aim was to provide even greater flexibility and user friendliness with the new model. The CyberAir Mini is designed for various mission-critical applications and therefore provides reliable and cost-effective air conditioning of small server, equipment, UPS, and battery rooms.
Minimal footprint for more white space in the data center
Maximum reliability and flexibility with a small footprint – the CyberAir Mini comes in four sizes and ensures economical and reliable operation for all applications. Thanks to their compact design, the various unit sizes all offer even more room for your IT equipment and diverse installation options to make optimum use of your room space.
Future-proof with low GWP refrigerants
STULZ offers efficient cooling solutions with low GWP refrigerants, minimizing your carbon footprint for the long term. With STULZ as your partner, you can satisfy the upcoming regulations for refrigerants, noise, and a reduced carbon footprint, for future-proof and environmentally friendly systems.
Available with:
R513A: GWP = 631 (for A, G, GE, and ACW systems)
R454C: GWP = 148 (for G and GE systems)
Optimized unit design for sound insulation and maximum efficiency
The modern design of the CyberAir Mini series not only enables precise air conduction with low pressure losses – the optimized layout and EC fans also ensure low noise emissions.
During the unit’s development, maximum energy efficiency was the key priority. To do this, we used EC technology and generous heat exchanger and filter surface areas, to cut running costs to the minimum. On top of this, options such as Direct and Indirect Free Cooling increase energy efficiency to the max.
Precise control for maximum reliability
Thanks to its flexible and precise control of the room temperature and air humidity, the CyberAir Mini ensures maximum reliability in continuous 24/7 operation, 365 days a year. In addition, to achieve the highest standards of reliability and usability, STULZ develops the control system in-house, ensuring that software, hardware and air conditioning units are perfectly harmonized. An optional touchscreen offers clear and simple navigation and intuitive controller operation.
Further advantages:
- Energy management: Helps to optimize the energy demand of interconnected systems and enables the operation of several air conditioning units in parallel across more than one machine
- Maximum reliability: Redundancy management, integrated standby management with backup operation, and differentiated warning and alarm system
- Very easy to service: Plug and play installation and optimized control parameters for simplified servicing
- Monitoring: Start-up is simplified by direct BMS interfaces on the controller, support for all relevant BMS protocols, and a compact datapoint list.

The right system for your application
Energy efficiency, capital investment, operating costs, room size, noise protection, redundancy, local climate – every project has its own specific requirements when it comes to precise air conditioning. That’s why STULZ offers you the opportunity to have the units precisely adapted to your project’s individual requirements. The right air conditioning system is a crucial factor here. The CyberAir Mini is available in five different cooling systems, to help you achieve the ideal balance between investment, operating costs, and energy efficiency.
Air-cooled system based on the direct evaporator principle (A/AS)
Heat is extracted from the room air as it flows through the evaporator, and is then transferred to the refrigerant. The air conditioning unit and condenser are connected to one another by a closed refrigerant circuit. The refrigerant emits the heat to the outside air via the air-cooled condenser.
The AS system is equipped with stepless variable-speed EC compressors for maximum energy efficiency. The compressors feature integrated soft start and phase monitoring.
Liquid-cooled system based on the direct evaporator principle (G)
The water-cooled system works like the air-cooled system, with one difference: the heat from the refrigerant circuit is transferred to a cooling water circuit via a brazed plate condenser integrated in the air conditioning unit. This way, the amount of refrigerant required is low. The heat in the cooling water circuit is then discharged into the outside air via an external dry cooler.
Chilled water system with redundant air-cooled system (ACW)
Two independent cooling systems (CW and A) are combined in a single air conditioning unit to guarantee maximum reliability. If the main chilled water (CW) system fails, the air-cooled (A) system keeps the air conditioning going without interruption.
Hybrid Free Cooling system (GE)
This system functions like the GS system, but additionally features an integrated Free Cooling coil. This way, energy-intensive compressor cooling can be partially or wholly dispensed with at low or temperate outside temperatures. The heat is transferred directly to the cooling water circuit by the integrated Free Cooling coil, and discharged into the outside air via an external dry cooler.
Minimal compressor running time
Using Indirect Free Cooling, the hybrid Free Cooling system exploits the cooling potential of outside air as soon as outside temperatures allow. This enables energy-intensive compressor cooling to be partially or even wholly dispensed with.
Minimal refrigerant quantities
As the hybrid Free Cooling system is liquid-cooled, it only needs a minimal quantity of refrigerant. The result is environmentally friendly operation with reduced greenhouse gas emissions, for a forward-looking investment in the future.
Chilled water system (CW)
The air conditioning unit with CW system manages without a refrigerant circuit of its own, but requires a separate chiller. The air conditioning unit and chiller are connected to one another by a closed water-glycol circuit.
Synchronized complete systems
You too can benefit from our perfectly harmonized air conditioning solutions with chillers for indoor and outdoor installation. We would be happy to advise you and work with you to devise the best solution for your particular case.
