Antifrogen™ PG25

Antifrogen™ PG25 by Clariant is a high-performance propylene glycol-based heat transfer fluid specially engineered to meet the demanding requirements of modern data center cooling systems. It is ideally suited for advanced applications such as direct-to-chip (D2C) cooling, liquid cold plates, and closed-loop liquid cooling systems used in high-density computing environments.

Formulated as a ready-to-use solution with 25% propylene glycol, Antifrogen™ PG25 incorporates a robust package of advanced corrosion inhibitors based on Organic Acid Technology (OAT). This ensures long-term protection of multi-metal systems while maintaining optimal thermal efficiency.

Designed to support the growing needs of AI, HPC, and next-generation data centers, the fluid delivers efficient heat dissipation, stable performance under continuous thermal loads, and enhanced system reliability. Its optimized balance of thermal conductivity, viscosity, and chemical stability makes it a dependable choice for maintaining consistent operating temperatures and minimizing downtime in mission-critical infrastructure.
