SentraFlo SFN & Rack Manifolds

Refroid’s Server-to-CDU Flow Distribution Network

SentraFlo SFN & Rack Manifolds

About SentraFlo SFN & Rack Manifolds

The SentraFlo SFN(Secondary Fluid Network) and Rack Manifold System from Refroid form the secondary loop of the Direct-to-Chip Liquid Cooling (DCLC) architecture. Engineered for balanced and controlled coolant distribution to every server node in a rack, this system is rack-integrated, leak-resistant, and optimized for minimal pressure drop and ease of maintenance.

Key Features

Modular & Tool-Free Design
Field-installable components with dripless quick-disconnects for fast, safe servicing.
Rack-Integrated Manifolds
Pre-engineered manifold assemblies designed for direct integration with server cold plates
Flow Control & Monitoring
Optional inline sensors for monitoring per-rack coolant flow and temperature.
Non-Intrusive Maintenance
Equipped with isolation valves and blind ports to allow hot-swapping or reconfiguration without system downtime.
Smart Sensors
Real-time monitoring of pressure, temperature, flow rate, and leak detection, with analytics-ready data output.
