High cooling capacity for blade servers

Published: September 2005

A cooling system for blade servers based on carbon dioxide developed by Trox UK and Star Refrigeration can handle cooling loads of up to 30 kW per cabinet.

Trox UK and Star Refrigeration have developed a cooling solution for blade servers based on liquid carbon dioxide. Its method of heat transfer can cope with cooling loads of up to 30 kW per cabinet, with a 30% reduction in running costs compared with air or water solutions.

The basic principle and design philosophy of the C02RAC is to absorb all the heat rejected by blade servers, making the blade neutral to the space. Pressurised carbon dioxide in liquid form is circulated at 14°C and has significantly less environmental impact than HFCs.

Trox says that conventional air-cooled systems for IT suites can only deal with loads of 5 to 8 kW per cabinet, while the use of carbon dioxide can handle up to 30 kW.
