GMG launches G FLUID, a graphene-based coolant additive for data center cooling systems

Graphene Manufacturing Group (GMG) has launched G FLUID™, a patent-pending graphene water-based additive designed to improve heat transfer and curb microbial growth in data center and industrial cooling circuits. The product is sold as a 1-liter concentrate dosed at a 1:100 ratio into existing coolant loops, and targets the cooling water treatment chemicals market.

In preliminary internal testing, dosing demineralized water with G FLUID™ at 1%, providing 0.01% graphene by weight in the final solution, increased heat transfer by approximately 20%. Independent third-party laboratory testing to the EN 1276 standard found the same dosing reduced microbial growth by up to 87%, a factor GMG says matters for operators managing corrosion, fouling and maintenance costs in chiller systems.
