Data center liquid coolants

ZITREC® EC - more than PG25

ZITREC® EC direct-to-chip coolants are designed for modern data centers operating under increasing thermal loads. They deliver reliable heat transfer and long-term system protection in high-density server environments.

Why liquid cooling is becoming essential in modern data centers

The growth of AI and high-performance computing (HPC) is increasing the thermal demands on modern data centers. As CPUs and GPUs continue to become more powerful, chip power and heat output increase accordingly, making thermal management a growing challenge.

Traditional air-cooling infrastructure was not designed for this level of heat density. To address this, direct-to-chip cooling removes heat directly from CPUs and GPUs, making it a more efficient way to manage rising thermal loads in high-density server environments. This approach enables faster heat removal, improved system reliability and lower power usage effectiveness (PUE). The ZITREC® EC range was developed specifically for these next-generation cooling demands.

ZITREC EC ECO

Reduced carbon footprint, same trusted performance

The ZITREC® EC range is also available in an ECO version with a reduced Product Carbon Footprint (PCF). The ECO version uses base fluids derived from bio-based or recycled raw materials, allocated through a certified mass balance approach.

This approach allows renewable or recycled feedstocks to be used in production with full traceability through ISCC PLUS certification.

ZITREC® EC ECO delivers the same trusted cooling performance, system compatibility and operational reliability as the standard formulation, with the added benefit of a reduced PCF.
