DOWFROST™ LC Heat Transfer Fluids
Advanced Liquid Cooling for High-Performance Data Centers.


Optimize your data center’s thermal performance with DOWFROST™ LC Heat Transfer Fluids—engineered for direct-to-chip liquid cooling in Datacom Equipment Cooling Systems (DECS). As power densities rise and air cooling becomes inefficient and costly, DOWFROST™ LC offers a reliable, cost-effective solution for next-generation thermal management.


Why Choose DOWFROST™ LC?
Superior Corrosion Protection
Specially formulated to protect high-surface-area copper and other common metals in liquid-cooled systems.
Freeze Protection to -40°C (-40°F)
Available in two concentrations—LC 25 and LC 55—to meet your specific temperature and performance needs.
Fluorescent Leak Detection
Dyed bright yellow for easy visual identification of leaks during maintenance.
Optimized for Direct-to-Chip Cooling
Designed for use in in-rack or external Cooling Distribution Units (CDUs) across multiple server racks.
What are the Benefits of DOWFROST™?
Free annual fluid analysis and customized reports for systems greater than 250 gallons of concentrate
Made with Dow PuraGuard™ Propylene Glycol USP/EP, one of the highest purity propylene glycols available on the market – with a specified purity of 99.8% or greater
DOWFROST is NSF-certified and all fluid ingredients are Generally Recognized As Safe (GRAS), making this fluid suitable for use where incidental food or drinking water contact may occur
Compatible with common metals (including carbon steel, stainless steels, cast iron, copper, brass, bronze, and solder) and most plastic pipe (HDPE, PEX, PP)




DOWFROST™ HD
DOWFROST™ HD inhibited propylene glycol (PG) is comprised of about 94% PG and 6% corrosion inhibitors. DOWFROST™ HD (heavy duty) has a lower PG composition to allow for a higher concentration of corrosion inhibitors for maximum protection and rust prevention. These additional components do not compromise toxicity fluid and provide enhanced corrosion protection that is unsurpassed in the industry.
DOWFROST™ HD has a fluorescent-yellow color and can operate at higher temperatures than regular DOWFROST™. DOWFROST™ HD is suitable for use in environments between −50°F and 325°F (−45°C and 160°C).
