Smart pump solutions for CDUs and direct liquid cooling loops. Precise control, superior efficiency. iNERGY keeps AI data centers cool, efficient, and always on.
Liquid cooling is the critical frontier for AI data centers pushing thermal density limits. inergy's pump driver ICs deliver the reliability, control precision, and efficiency needed for 24/7 always-on cooling loops in CDUs and rack-level liquid cooling.
From rack-level CDUs to direct-to-chip liquid cooling, inergy pump ICs address every layer of modern AI datacenter thermal management.
Four product families covering all voltage tiers and motor configurations for AI server fans and liquid cooling pumps — now including the new iU6395 N/N FOC controller recommended for high-current 12V designs.
