SentraFlo CDU

Refroid’s Coolant Distribution Unit for Direct-to-Chip Liquid Cooling

SentraFlo CDU

About SentraFlo CDU

The SentraFlo CDU from Refroid Technologies is a high-performance, liquid-to-liquid heat exchange system designed to connect facility water systems with a secondary coolant loop for direct-to-chip liquid cooling (DCLC). It plays a pivotal role in maintaining thermal stability in high-density compute environments by efficiently circulating and conditioning dielectric or water-based coolant.

Key Features
