RowCool for effective heat removal in data centers

As the power density increases in modern data centers, traditional precision cooling fails to provide complete cooling for the following situations:

  • Load variations for peak and off-peak period
  • High power density
  • Uneven heat distribution

The Delta InfraSuite Precision Cooling RowCool Chilled Water can effectively solve the above problems.

 

Applications:

  • High power density rack area
  • Environment that requires precise environmental control

Precision Cooling - RowCool 70kW


Features

High Availability
Built-in dual input for better power reliability
Panel made of cold-rolled steel plate and coated with surface electrostatic spraying of epoxy is highly resistant to rust
Built-in leakage detector capable of leak display and alert
Modular rack design readily expandable by load to enable quick configuration of new cooling units
Built-in manual dehumidifying for quick and precise dehumidification
Supporting group control and used as backup

High Flexibility

Chilled water pipe suitable for both top and bottom insertion, with top and bottom input power wiring, providing flexible configuration as required
Wheels on bottom for easy moving to locations that need cooling
Disposable filter with high efficiency (MERV 8 ASHRAE 52.2)
Remote monitoring can be carried out through SNMP card, providing more comprehensive system protection
Optional reheater and humidifier accessories for more precise temperature and humidity control

High Efficiency

To comply with the high power density of racks, the RowCool series cooling capacity can increase up to 120kW (HCH1CD0) without changing footprint
– for RowCool 95kW
When Applied to the high temperature settings of inlet water, outdoor units save on power consumption by up to 15~20% when the chiller water temperature increases from 5°C to 12°C
Continuously variable speed fan design for energy saving
Cooling system capable of variable flow control for energy saving
Built-in vortex wafer flow meter capable of monitoring chilled water flow that renders easy display of system status
