Press release
ThermaGraph for closed water loops and ThermaGraph-D for single-phase immersion give operators a new fill for the hardware they already run.
CHARLOTTE, NC — October 23, 2026 — Graphene Integrations today announced ThermaGraph, its line of graphene coolants for data center liquid cooling. The line has two separate products: ThermaGraph, graphene in deionized water for indoor closed loops, and ThermaGraph-D, graphene in white mineral oil for single-phase immersion tanks.
Internal heat-transfer results and system evaluation
Turn that promising thermal result into a plant decision by comparing the same heat load and operating conditions. Log flow, inlet/outlet temperatures, pressure drop, pump, fan and chiller electricity; inspect filters, corrosion coupons and material compatibility. Water-based ThermaGraph is not a dielectric and must not immerse live electronics.
Same hardware, new fill
ThermaGraph works on the fluid side. It replaces the liquid that carries heat away from cold plates, CDUs, direct-to-chip and rear-door heat exchangers in indoor, closed copper loops where freeze protection is not specified. It is a new fill, not a top-off, so glycol loops are drained first. Graphene loading is low, 0.5 to 1.5 wt% in ThermaGraph and 0.05 to 0.20 wt% in ThermaGraph-D, and is stated on the certificate of analysis. ThermaGraph-D is a dielectric fluid for boards that sit directly in a single-phase tank. The two products should not be mixed or used in place of each other.
Who it's for
ThermaGraph is for operators, cooling engineers and integrators who want to test a new fill in a system they already run, using their own baseline data. Both products are patent pending and made in the USA.

About Graphene Integrations
Graphene Integrations is a US graphene manufacturer in Charlotte, NC, making graphene-enhanced additives for coolants, lubricants, concrete and coatings. The company makes graphene and supplies it pre-mixed in water, solvents, resins and oils, never as a dry powder, so manufacturers can add it to products and processes they already run. Its products are patent pending and made in the USA. Learn more about Graphene Integrations.

From heat-transfer performance to an efficient cooling loop
ThermaGraph™ is a complete water-based fill for suitable closed loops, with 0.5–1.5 wt% graphene in the supplied fluid—not a top-off dose. GI’s +6–18% higher convective heat-transfer coefficient versus a glycol baseline comes from internal pumped-loop tests. It is not independent field validation or an equivalent percentage electricity saving.
Turn that promising thermal result into a plant decision by comparing the same heat load and operating conditions. Log flow, inlet/outlet temperatures, pressure drop, pump, fan and chiller electricity; inspect filters, corrosion coupons and material compatibility. Water-based ThermaGraph is not a dielectric and must not immerse live electronics.
DOE’s liquid-cooling evaluation illustrates system-level metering; it did not test GI fluid. Assess environmental outcomes using measured kWh, the actual electricity mix, fluid manufacture, replacement, transport and disposal. Improved heat transfer is an opportunity to optimize the system, not a measured GI carbon footprint.
