Immersion cooling
Involves immersing elements such as entire servers or networking equipment in non-conductive cooling fluid. Effective for high-density equipment, such as that used in data centres and high-performance computing operations. Learn more about Immersion cooling.

Immersion vs. air cooling
Traditionally, facilities like data centres have relied on air-based cooling systems that require extensive equipment like fans and heatsinks to provide cool air – equipment that reduces operational efficiency through its need for additional space and high energy consumption.
Immersion cooling technology offers a completely different approach. Circulating specially formulated cooling fluids around the equipment, it dissipates heat effectively. This contributes to improved equipment performance through better temperature regulation while providing greater operational and energy efficiency.

Title: Shell_Skybox_video_07_11
Duration: {1:00} minutes
Description:
{Shell has converted its high-performance computing cluster at the Houston Skybox data centre to immersion cooling.}
{Compared with air cooling, immersion cooling offers reduced electricity use, carbon footprint, water consumption, floor space and cost of ownship, with increased processing performance. Shell is an early adopter of this technology and has converted its high-performance computing cluster at the Houston Skybox data centre to immersion cooling.}
