TL;DR:<\/strong><\/p>\n\n\n\n

\u2022 India’s growing AI ecosystem requires sustainable and energy-efficient digital infrastructure.<\/p>\n\n\n\n

\u2022 Traditional cooling methods consume large amounts of water and energy, making them increasingly unsustainable for modern AI workloads.<\/p>\n\n\n\n

\u2022 Varuna, RackBank’s patented single-phase immersion cooling technology, cools servers by submerging them in a non-conductive engineered fluid instead of relying on water-intensive cooling systems.<\/p>\n\n\n\n

\u2022 The solution delivers up to 90% lower water consumption, 95% lower cooling OPEX, 45% lower carbon emissions, and a cooling PUE of less than 1.03.<\/p>\n\n\n\n

\u2022 Beyond immersion cooling, RackBank is advancing sustainable AI infrastructure through renewable energy adoption, carbon offset programs, Smart DCIM monitoring, and strategic expansion into Tier-2 cities.<\/p>\n\n\n\n

\u2022 Varuna represents the future of sustainable datacenter cooling and responsible AI infrastructure in India.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

As India races to build the digital infrastructure needed to power its AI ambitions, the need for sustainable AI infrastructure<\/strong> and water conscious datacenters<\/a><\/strong> has never been greater. Traditional cooling systems consume significant amounts of water and energy, creating new challenges for the future of sustainable datacenter cooling<\/strong>. This is where Varuna immersion cooling<\/strong> technology is redefining how modern AI infrastructure<\/strong> is built and operated.<\/p>\n\n\n\n

At RackBank, we believe this is a problem that demands a fundamental rethink, not just incremental improvement. That is why we’ve built Varuna, our patented immersion cooling system designed to support the next generation of green datacenters<\/strong> and high-performance AI workloads.<\/p>\n\n\n\n

Scaling Sustainable AI Infrastructure with Varuna<\/h2>\n\n\n\n

Varuna immersion cooling<\/a><\/strong> is RackBank’s patented single-phase immersion cooling<\/strong> system. Rather than blasting cold air or relying on water-intensive cooling methods, Varuna submerges servers directly in a non-conductive, non-toxic engineered fluid. The liquid absorbs heat directly from the hardware, which is then transferred away efficiently through a heat exchanger, no cooling towers, no evaporation, and no water waste.<\/p>\n\n\n\n

The fluid itself remains in a liquid state throughout the entire process, which is what defines it as single-phase immersion cooling<\/strong>. This makes it significantly more stable, reliable, and efficient than many conventional cooling systems and two-phase cooling technologies that require the coolant to boil during operation.<\/p>\n\n\n\n

As organizations search for sustainable cooling solutions for AI infrastructure<\/strong>, immersion cooling is emerging as one of the most effective approaches available today. The benefits of single-phase immersion cooling technology<\/strong> extend beyond energy efficiency, delivering improved hardware performance, longer equipment lifespan, and significantly lower operational costs.<\/p>\n\n\n\n
