KT Cloud to adopt liquid immersion cooling system for data centers

South Korea’s KT Cloud on Tuesday said it signed a deal with Immersion 4, a Swiss provider of liquid cooling solutions, to install next-generation immersion cooling technology at KT Cloud data centers.

Immersion cooling removes heat by immersing information and communications technology equipment in a dielectric solution in which electricity does not flow. This eliminates imbalance in server room temperatures and fan noise at data centers that can occur with an air-cooling system.

Power consumption and carbon emissions are also reduced, as well as the building space needed for cooling.

“Heat is the main culprit that turns data centers into ‘electricity-eating hippos,’” a KT Cloud source said. “Next-generation immersion cooling technology is crucial for data centers.”

Immersion 4 has self-developed liquid immersion cooling fluid and system technology.  Both companies under their agreement will exchange technologies for applying the liquid immersion cooling system to KT Cloud data centers and cooperate to achieve efficient and stable operations.

KT Cloud said higher cooling capacity will ease the adoption and operation of high-capacity and high-density servers. The goal is to cut a data center’s operating costs and create energy efficiency benchmarks.
