High Eciency
• Optimized for high temperature chilled water applications, the heat
exchanger design increases the overall eciency of precision cooling
systems.
• The Electronically Commuted (EC) Fans design provides variable fan
speed control for optimal speeds in real-time according to load changes,
avoiding unnecessary power waste.
• Closely couples to IT heat loads and quickly adapts to load changes for
direct and eective heat removal.
High Availability
• Supports dual power feed input and is suitable for any tier level of power
reliability architectures.
• Thanks to the inherent redundancy design of the fan system, other fans
automatically increase fan speeds to make up for the required airow if
one of the fans malfunctions.
• 1+1 redundant design of the power modules increases reliability
(applicable to some models).
• Hot-swappable power module and fan design allows replacement without
the need of a power shut down while malfunctioning.
• The smart group control function is equipped with rotation, back up,
competition free, and soft start functions.
• Comprehensive operation monitoring such as chilled water ow and leakage detection allows full control of machine
operations and the ability to take necessary troubleshooting measures in real-time.
High Flexibility
• Top or bottom piping and wiring options are available to satisfy the pipeline design needs for dierent data center
requirements.
• Multiple communication interfaces satisfy the surveillance and communication needs of a variety of data centers.
• High eciency lter (MERV 8) or washable lters (MERV 1) are available for users to choose according to their needs.
• Equipped with casters for easy movement and positioning during installation without the need for additional handling tools.
• 2.4-meter-high models using the 52U rack are also available to customers. (For special height requirements, please
