The Brief

"In 2009 PayPoint needed to increase the cooling density of their Data Center by 50% without having to expand the real estate footprint and required a cost effective cooling solution to enable this."

"The site had an existing 40kW + 40kW CRAC DX system for which they required a Tier 3 (N+1) redundancy working system to attach to their existing infrastructure."

"The project had to be installed and commissioned without any downtime to their server room operations as this is a critical Government hosting site."

The Cooling Solution

The design comprised of 22 racks and a mixture of 15 C4 and C8 ColdLogik rear coolers. Some rear coolers were retrofitted to existing cabinets via interface frames onto the rest onto USpace ColdLogik compliant cabinets all of which were installed into the working data center without any shut down of operations.

The ColdLogik solution increased the kW capacity from 40kW to 100kW - as the building was on the edge of utility power feed maximum it also reduced this by 16kW (60-80amps).

The combined solution enabled a room density of 2-7kW per rack with duty transfers between racks during a 24 hour period.

Pre-fabricated pipe work was utilised to enable a quick installation and the ColdLogik solution replaced the overloaded CRAC system which was retained as a back up.

Complementing the CL20 rear coolers were 2 x50kW chillers and a 100kW dry air cooler.

Because the client required the pipework to run through their offices to the data center - to provide additional peace of mind throughout the data center, a 100kW patented Leak Prevention System was included bringing together the cooling and data center pipework.
