Ahmedabad, August 7, 2026: KühlTherm has launched its indigenous Rear Door Heat Exchanger (RDHx) and Cooling Distribution Unit (CDU) for AI data centres, alongside unveiling India’s first integrated liquid cooling testing and verification laboratory in Ahmedabad.
The new products are designed to address the needs of Indian data centre environments, taking into account local climate, grid fluctuations and infrastructure requirements. KühlTherm’s RDHx and CDU will be integrated with the company’s proprietary NexusFlow OS, an AI-powered thermal intelligence platform aimed at improving cooling efficiency, reducing thermal throttling, and supporting high-density AI and high-performance computing workloads.
First integrated liquid cooling lab
The Ahmedabad laboratory is the first in India to offer integrated liquid cooling validation and verification, enabling KühlTherm to test its products under real-world operating conditions before deployment. The company said this facility will help establish product reliability and trust for data centre operators.
Expansion plans and manufacturing targets
KühlTherm currently manufactures the complete thermal loop for AI data centres, from chip to chiller, entirely in India. The company aims to expand its manufacturing capacity from 300 MW to 2 GW by 2027 as part of its growth strategy.
Sector context and recent funding
According to a study by Cambridge-led researchers, land surface temperatures around AI data centres without adequate cooling rise by an average of 2 degrees Celsius after they open, impacting both the environment and data centre operations. KühlTherm’s solutions are engineered to help operators reduce thermal throttling, improve cooling efficiency, and enable high-performance computing at scale.
The announcement follows KühlTherm’s recent $1.1 million Seed funding round led by Arkam Ventures, intended to support the scaling of its liquid cooling solutions for AI data centres, hyperscale infrastructure, and other high-density computing environments.
Leadership comments
Shailesh Bishnoi, Founder and CEO of KühlTherm, said the launch of the RDHx and CDU is part of the company’s goal to help customers adopt next-generation cooling technologies and strengthen India’s position in the global thermal management ecosystem. “India is entering a major data centre buildout cycle, and decisions being made today will define the efficiency and sustainability of thermal management infrastructure for years to come,” Bishnoi said.
KühlTherm is a precision liquid cooling technology company that designs and manufactures thermal management solutions for high-performance computing environments, including patented Direct-to-Chip cooling, Rear Door Heat Exchangers, immersion cooling systems, coolant distribution units, and the NexusFlow OS platform.
