Overview
DOWFROST™ LC 25% is a specially formulated inhibited propylene glycol based thermal fluid for use in datacom equipment cooling systems or DECS loops. DOWFROST™ LC 25% is a prediluted solution of propylene glycol in water with proprietary anticorrosion inhibitors to maximize thermal transfer and cooling control.
DOWFROST™ LC 25% heat transfer fluid provides freeze protection for the system loop down to −14°F (−10°C) and exhibits incredible protection against metal corrosion even for components with high copper surface area.
DOWFROST™ LC 25% is manufactured from virgin Dow PuraGuard™ USP-grade propylene glycol, resulting in a consistent, high-quality fluid that resists foaming, premature degradation, and poor odors from inferior glycol fluids.
