Stulz-ATS CyberAiR, the Greener Way of Cooling your Data Center
Today, more than ever, the need for less energy consumption is a critical part of your data center cooling solution. The Stulz-ATS CyberAiR family of floor mounted precision air conditioners is the answer.
Whether you are building a new facility or updating a legacy data center, Stulz-ATS has an ideal cooling solution for every application and every room size. Our large capacity, ultra-efficient, Chilled Water CRAH’s with EC plug fan technology are available with right and left hand piping connections for easy replacement of your outdated, inefficient, maintenance intensive, belt-driven computer room air conditioner.
Our exclusive Chilled Water CRAH cabinet design in combination with the energy efficient electronically commutated (EC) plug fan provides an immediate energy savings of up to 30% over units using conventional fan technology with on/off control. Intelligent control of this exclusive combination of technology with the use of redundant units can allow users to see savings over 50% when compared to those same conventional units with on/off control.
Stulz-ATS leads the industry as the first manufacturer in the US to offer CRAC/CRAH units with EC Fan technology, and the only one with measurable experience. We have thousands of CRAH's with this technology deployed in some of the largest data centers across the US. Our expertise affords you the luxury of a top of the line product, proven over time to maximize cooling and energy savings simultaneously.
The EC Fan is available as a standard in our Compact-CWE high capacity chilled water CRAH's ranging from 10-70 tons, and as an option in our VFS CyberTWO floor mounted direct expansion computer room air conditioners which range from 6-30 tons.
With expert insight and experience, our specialists are ready to help you solve your precision cooling challenge.

Stulz-ATS Precision AC's with EC Fan's offer on-demand, automatic and manually controllable variable speed capability and achieve the benefits of improved efficiency, reliability and low running costs.
Advantages of the EC Fan
- Lower running cost - significantly more efficient motor
- No belt drives - reduce maintenance (no changing or adjusting)
- No power transmission losses through belt and pulleys
- No belt dust and therefore no contaminating of mission critical equipment, including servers, disk drives, telecom switch gear, etc.
- Longer filter change intervals
- Lower (audible) noise - no AC inverter whine
- Less vibration
- Site adjustable air volume (fan speed) from CyberAiR C6000 controller and therefore easy adaptation to changing conditions
- Increased net cooling - reduced cooling load on refrigeration plant
- Integrated electronics - no need for secondary electronics e.g. inverters and filters
- Soft start - without high inrush current - no belt slip or peak noise
- Fan direction always correct - no phase directional
- High efficiency is maintained at variable speeds / little efficiency penalty at reduced speeds
- Integral overload protection
- Backward curved aerodynamically optimized impeller
- Due to individual direct drive nature of EC Fan, redundancy is built into each unit containing multiple fans...particularly Chilled Water CRAH units (greater allowable coil air volume range)
- Fan speed is continuously adjustable via a signal from the system controller with the use of VFD's
- Optimized air distribution into raised floor to avoid hot spots
