Refroid Technologies, an Indian innovator in data center cooling solutions, has launched the SentraFlo Series, India's first indigenously developed Liquid-to-Liquid Coolant Distribution Units (CDUs) designed for Direct-to-Chip Liquid Cooling (DCLC) applications. This development signifies India's growing ability to support high-density AI and HPC workloads with locally made solutions.

The SentraFlo cooling ecosystem is engineered for both hyperscale and enterprise-grade deployments, featuring CDUs, rack manifolds, and a secondary fluid network (SFN) plumbing architecture. It offers customizable capacities ranging from 200 kW to 2 MW, positioning it as a scalable and intelligent CDU solution.

Satya Bhavaraju, CEO of Refroid, stated that the launch reinforces India's emergence as a hub for innovation in the global liquid cooling landscape and will enable modern data centers to scale performance while enhancing operational efficiency and sustainability.

Key features of the SentraFlo Series include:

• Scalable CDU capacities from 200 kW to 2 MW with configurable motors, BPHEs, sensors, and filters.
• Advanced monitoring with built-in, redundant sensors for pressure, temperature, flow, turbidity, and pH for continuous health diagnostics and maintenance.
• 25-micron secondary fluid filtration with minimal pressure drop for high coolant purity.
• Dew Point Control technology to maintain dry white space and eliminate false leakage alarms.
• Hot-swappable sensors, redundant motors, and controllers for enhanced fault tolerance.
• Tri-clamp fittings and SS304L/SS316L construction on all wetted components for reliability and serviceability.
• Integrated 10-inch HMI panel and real-time remote monitoring dashboard.
• Support for SNMP, TCP/IP, BACnet, and other legacy protocols for autonomous or dark data center operations.

Srikanth Kanduri, CTO of Refroid, mentioned that the design philosophy centers around reliability, efficiency, and intelligence, with features like reinforcement learning algorithms for dynamic PUE optimization and smart auto-profiling of coolants.

Refroid SentraFlo CDU systems will begin shipping by the end of June 2025, including full integration with rack manifolds and SFN plumbing.
