In data centres across the world, servers are stored in racks and cooled by air to keep them from overheating. Typically, these air-based solutions require large set-up costs, because it’s necessary to have raised floors and enormous amounts of space reserved for the cooling systems and their generators. However, despite the amount of power fed into this system, Power Usage Effectiveness (PUE) rarely dips below 1.8, circulation remains uneven and inefficient with “hot spots” developing on occasion, and dangerous particulates are distributed through this high-turbulence environment.

Introducing Server Immersion Cooling

Server Immersion Cooling is the future of green data centres.

With this technology, servers are submerged in thermally conductive, dielectric liquid, which provides a 45% greater energy efficiency than that of air cooling. The capital investment is substantially reduced because servers no longer require the passage of air across them, and the environment is much quieter.

Immersion cooling offers significant benefits in three key areas:

  • Financial
  • Efficiency
  • Logistics

With our unique SI Cooling solution, your work environment will be much quieter, as there will be no more loud, power-consuming air cooling units or fans. Your server’s density will be higher for the same power consumption, with faster servers that operate cooler within an even heat distribution. Your servers will experience lower fail rates, since they are immersed in coolant will be protected from over heating, moisture, oxidation and dust.

The SI Cooling solution more effectively transfers the heat from the computing system, resulting in a lower chip temperature and no more “hot spots.” A PUE of 1.06 will be achieved regularly. The lower energy required to cool the environment, coupled with the lower temperature of the servers and the greatly reduced fail rates, means most users will see their ROI achieved within one year.
