Graphene Integrations supplies ThermaGraph™ graphene coolants from the USA for data center liquid cooling. ThermaGraph™ is a water-based graphene coolant for indoor closed loops; ThermaGraph-D™ is a dielectric fluid for single-phase immersion. In internal testing results, ThermaGraph™ showed 6–18% better heat transfer versus glycol. Pricing is by quote, and these figures are laboratory results, not a field-performance guarantee.
What we supply
We are a US graphene manufacturer in Charlotte, NC. For data centers, the product family is ThermaGraph™ graphene coolants:
- ThermaGraph™ — graphene pre-mixed in deionized water for indoor closed-loop liquid cooling (cold plates, CDUs or rear-door heat exchangers, as discussed on the product page).
- ThermaGraph-D™ — a dielectric fluid for single-phase immersion cooling, where servers are submerged in a tank.
Graphene is supplied pre-mixed in the fluid, never as powder. The two products are not interchangeable. A short comparison of loop versus immersion is in ThermaGraph vs ThermaGraph-D. For lab context, see graphene coolants for AI data centers: lab vs field.
What the 6–18% figure means
ThermaGraph™ showed a 6–18% better heat transfer coefficient than a glycol baseline in internal testing results. That is laboratory data from GI, not a third-party field trial, and it should be labeled as internal testing results when it is quoted. It is not a promise of a 6–18% energy saving in a specific hall, CDU or climate. Facility teams should evaluate the fluid in their own loop or tank, including compatibility, filtration, freeze protection and leak behavior. The product FAQ on the coolants page addresses topping off an existing glycol loop, freeze protection, and whether graphene stays in suspension.

|---|---|
| Who supplies it? | Graphene Integrations, a US graphene manufacturer in Charlotte, NC, founded in 2015. |
| Closed-loop water cooling | ThermaGraph™, graphene pre-mixed in deionized water. |
| Immersion cooling | ThermaGraph-D™, a dielectric fluid for single-phase immersion. |
| Published heat-transfer result | 6–18% better heat transfer versus glycol (internal testing results). Not a field guarantee. |
| Form | Pre-mixed fluid, never graphene powder. |
| Pricing and samples | Quote-only. Samples and evaluation support are available on request. |
Typical GI graphene additive doses in other products are 1% to 7% by weight; coolant selection is about choosing the right ThermaGraph™ or ThermaGraph-D™ fluid for the cooling method, not about treating these coolants as a generic 1–7% add-in to an unknown loop. Start with the data center coolants page and, if useful, the nanofluid coolant note.
Frequently asked questions
Are the 6–18% heat-transfer results field-proven?
No. They are internal testing results against a glycol baseline. They should not be read as a measured saving in a particular data center. We help facilities evaluate the fluid in their own equipment.
Can I pour ThermaGraph™ into an existing glycol loop?
Do not assume it is a drop-in top-off. The product page explains the difference between a water-based closed-loop coolant and a glycol system, including freeze protection. Ask us before mixing fluids.
Do you sell a graphene powder for me to mix into coolant?
No. Graphene is supplied pre-mixed in the coolant, never as powder.
How do I start an evaluation?
Request a quote or samples through the quote form or samples page, and tell us whether you are looking at a closed water loop or single-phase immersion. You can also call 704-659-3682 or email sales@grapheneintegrations.com.
