Global lubricant brand Castrol is using its expertise to pivot towards immersion cooling technology solutions for data centres handling increased AI demand
As data centre operators race to meet the growing computational demands of AI, they also face significant environmental challenges. How do they cool powerful hardware efficiently? Castrol may have found the answer.
The global lubricant brand is now leveraging its 125 + years of fluid expertise in the automotive sector to develop cooling solutions for the data centre industry.
“ We see an enormous opportunity in improving the thermal management of data centres,” says Chris Lockett, Senior Vice President for Electrification and Castrol Products Innovation.“ When we look at the way data centres are cooled today with air cooling, a significant amount of power is being utilised to keep the servers cool – up to 40 % of the data centre’ s power.”
The evolution away from air cooling Immersion cooling involves submerging server components directly in dielectric fluids that conduct heat, but not electricity. For the data centre industry, moving away from traditional air cooling towards immersion cooling solutions represents a paradigm shift.
