Uninterruptible Chilled Water Supply (UCS) Tank for Data Center

Executive Summary

FT Energy implemented an Uninterruptible Chilled Water Supply (UCS) tank that enabled a high density data center to survive a power outage without costly thermal damage to servers. The system, based on auxiliary chilled water storage tanks, kept the data center cool when an outage caused the chillers to shut down.

Why is this system important to data center

In data centers with high power and heat densities, a power sag or outage can cause rapid temperature increases. This is because cooling systems temporarily shut down, while servers keep producing heat because they are on an uninterruptible power supply (UPS).

To overcome this problem, FT Energy implemented an Uninterruptible Chilled Water Supply Tank(UCS) at a large regional hub data center. The system, based on pressurized tanks containing chilled water operated successfully during an outage that lasted several hours.
