The IT industry is responsible for a significant share of global electricity use. According to the International Energy Agency, data centre operations together with the data transmission network are responsible for over 2% of the global electricity consumption in 2020  With sizeable growth expected in the industry, this share is expected to rise.
While the energy consumption of this sector is significant, the benefits of the services offered, and the economic activity supported by data centre services are many times larger.
Cooling is critical to safely operate computing equipment and yield maximum performance. The energy required for the cooling of a data centre makes up close to 40% of the total energy consumed . To operate data centres sustainably efficient cooling is key. Liquid immersion cooling – where the hardware is fully submerged in a dielectric fluid to transport heat away from the equipment - offers a great energy saving potential for the industry and has the potential to decrease the impact this sector has .
Castrol ON’s comprehensive range of single-phase immersion cooling fluids have been developed to meet the needs for data centre, edge computing, blockchain and other IT applications. Immersion cooling can help to increase the overall efficiency and sustainability of IT operation while ensuring hardware integrity due to material compatibility properties as well as ensuring safe operations.
Lower viscosity than conventional dielectric fluids, such as transformer oils, enabling efficient heat transfer and pumpability
Good thermal properties across the operating temperature range
Excellent electrical insulation to protect against breakdown
High oxidation resistance to maintain performance over the fluid lifetime while maintaining a low GWP
As a global leader in the lubricant industry Castrol is uniquely positioned to serve and support customers globally in the journey to adopt immersion cooling. Castrol can offer fluid solutions, analytical support and well as testing and validation with its global network of technology centre. Castrol relies on over 120 years of experience and has the capabilities to co-engineer solutions to suit your needs.
