All details about CyberAir Mini CW
MiniSpace becomes CyberAir Mini
With our MiniSpace series, we have introduced a system worldwide that reliably air conditions rooms with high thermal 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. CyberAir Mini is engineered for various mission-critical applications and therefore reliably and economically air conditions small server and equipment rooms, and rooms containing the UPS and batteries.
Precision and comfort air conditioners compared
Precision air-conditioning systems capable of regulating room temperature accurately were developed for equipment rooms. However, often comfort air conditioners are used there. Learn more about the reasons for better using a precision air-conditioning unit:
High sensible cooling capacity = Low operating costs?
The sensible part of the cooling capacity reduces the temperature, while the latent part dehumidifies the air. Comfort air conditioning units can use up to 50% of their energy for dehumidification, whereas precision units convert more than 95% of the energy used exclusively into cooling capacity. The technology required to achieve this pays off quickly in terms of lower operating costs.
Air Distribution, Heat Dissipation and Filtration
Precision air conditioning units from STULZ filter and circulate three times the amount of air as comfort units with the same rated capacity. They reliably dissipate isolated thermal loads even from distant corners of the room, while continuously monitoring and precisely controlling the temperature and air filtration.
Controlled Temperatures
Information and communication technology only works reliably and without faults within a relatively narrow temperature range. STULZ precision air conditioning units ensure optimum temperature accuracy with maximum tolerances of +/- 1 °C, while comfort units can normally deviate from the set value by as much as +/- 3 °C.
Controlled Humidity
Unlike comfort air conditioning units, precision units feature strictly controlled and accurate dehumidification (tolerance +/- 5% relative humidity), as too much humidity can lead to condensation and corrosion, while too little can cause static charges, data loss and damage to hardware.
Excellent Reliability
Comfort air conditioning units mainly operate in summer and only for a few hours each day. By contrast, precision units need to be available whenever the electronic equipment to be cooled is in operation. For most server room cooling systems, this is the case for 24 hours a day, 365 days a year.
This is why STULZ makes such high demands on the quality of their precision server room cooling units and is able to offer high availability systems with 99.999 % reliability.

- Quiet running
- Long life
- Maintenance-free
- Adjustment to the given conditions with pinpoint precision
Chilled water system (CW)
Units with a chilled water system manage without a refrigerant circuit of their own, but require a separate chilled water generator. The room air conveyed by the fan flows through the direct cooling unit, which transfers heat to the water/glycol mixture. A chiller removes the heat from this water/glycol mixture. The air conditioning unit and chiller are connected to one another by a closed water/glycol circuit.
Control and monitoring
Thanks to its flexible and precise control of temperature and humidity, CyberAir Mini ensures maximum reliability during continuous operation 24/7, 365 days a year. In addition, to achieve the highest standards of reliability and usability, STULZ develops the controller in-house, ensuring that software, hardware and air conditioning units are perfectly harmonized. An optional touch display provides clear menu navigation and intuitive operation of the controller.
