Delta InfraSuite Precision Cooling
RowCool Series 43kW, Chilled Water
Delta’s RowCool CW oers outstanding performance in high temperature chilled water applications via the optimized
design of its heat exchanger. With industry-leading high cooling capabilities, the RowCool CW increases the overall
cooling eciency of data center precision cooling systems. The RowCool CW provides the best cooling solutions for
data centers over hundreds of kW, focusing on both high eciency and high density.
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.
• 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.
