The Fujitsu Server PRIMERGY Liquid Immersion Cooling System cools the entire IT devices equally by immersing it in cooling fluid.
The system cools the entire server equally, and because the heat generated by the server is not emitted into the server room, air conditioning equipment is unnecessary. The cooling system provides high energy efficiency because the server does not require internal cooling fans, boasting a power usage effectiveness (PUE) ratio of 1.07. This not only reduces the server system’s overall power consumption, by approximately 40% compared to air cooling systems (including its cooling equipment), it also enables approximately double the server density in the same installation space, contributing to reductions in the total cost of ownership (TCO).
By using Fujitsu’s specially developed, well-sealed ‘immersion bath,’ this system minimises vaporisation of the cooling fluid. Maintenance of the system is easy because the fluid used as a cooling medium is also non-combustible, not harmful to humans, and does not need to be regularly replaced as it does not deteriorate.
