TMC LC-25 Heat Transfer Fluid is an inhibited Propylene Glycol water-based fluid blend with a low pH and is a direct replacement for PG25. It is specifically designed for liquid cooling in data centers because of its balance of thermal performance and safety. It provides freeze point suppression, along with protection against corrosion, bacterial growth, and hard scaling.

APPLICATIONS

TMC LC-25 is designed for liquid cooling in data centers and IT infrastructure for direct, DTC and closed-loop systems. It can be used as an alternative for all types of PG25 that are used for DLC cooling of data centers. It is a versatile, inhibited heat transfer fluid. This fluid contains an advanced alkalinity additive for a longer working life, reduced maintenance costs and enhanced protection of capital assets.
