A FinTech Pioneer's Journey to Immersion Cooling
Industry: Energy Sector – Financial Location: India Infrastructure: 4MW Data Center
The Challenge: Scaling in a Tropical Climate As one of India's fastest-growing digital payment platforms, this FinTech leader faced critical infrastructure challenges. Trying to process millions of daily transactions in India's tropical climate, their air- cooled data centers were hitting performance and efficiency limits. Rising energy costs, limited capacity for high-density workloads and ambitious sustainability commitments created real urgency. They risked falling short on performance while missing the opportunity to return unused power to the grid.
The Solution: Hybrid Innovation The company chose a ground- breaking hybrid approach combining air cooling, direct contact liquid cooling (DCLC), and liquid immersion cooling across their 4.8MW facility. The immersion setup features 48 Dell 1U servers submerged in dielectric fluid within each Green Revolution Cooling (GRC) tank. A Coolant Distribution Unit (CDU) connects four immersion racks, transferring heat from fluid to water, then cooling via rooftop dry coolers. This eliminated traditional HVAC infrastructure while dramatically improving efficiency.
Measurable Results
PUE dropped from 1.6 to as low as 1.1 with immersion
Hybrid model averages 1.27 PUE - a 26% efficiency improvement
PUE 1.1
26% Gain
$ 1.58 megawatts of power savings - enough for 400,000 homes
Immersion-cooled servers achieved 99.9997% reliability - 8x higher than air-cooled counterparts
