Ahmedabad based startup KuhlTherm has closed a $1.1 million seed funding round led by Arkam Ventures, the company announced this week, as it moves to scale its precision liquid cooling systems for AI data centres and high density computing infrastructure across India and international markets.
Engineering for Rising Compute Demands
Founded in 2025, KuhlTherm builds cooling technology specifically engineered for the intense heat output of AI and GPU-based workloads. Its product line spans direct to chip cooling, rear door heat exchangers, immersion cooling systems, and coolant distribution units, unified under a proprietary software layer called NexusFlow OS.
The startup says conventional air cooling systems are increasingly unable to keep pace with the thermal demands of modern data centres, a gap it aims to fill with liquid based alternatives designed for local operating conditions.
Capital Allocation and Growth Priorities
KuhlTherm plans to direct the capital toward four priorities: deepening product development, expanding its research and testing infrastructure, growing its engineering and business development teams, and securing industry certifications needed to operate at scale. Building strategic partnerships is also part of the roadmap as the company positions itself for international expansion.
A Growing Infrastructure Bottleneck
Data centre cooling has become a pressing infrastructure concern as AI adoption accelerates. Denser server racks and GPU clusters generate more heat than traditional air cooling can efficiently dissipate, pushing operators toward liquid cooling to manage both performance and energy costs. For an India based startup, entering this space early—with technology adapted to local conditions—could translate into faster deployment and lower operating costs for domestic data centre operators, while also opening a path to compete in global markets facing similar constraints.
The Road Ahead
With fresh capital secured, KuhlTherm’s near term focus will be on scaling manufacturing, completing certifications, and building out its team. Its ability to convert seed funding into commercial deployments—both domestically and abroad—will be the key signal to watch in the coming months.
