Haydale reports 28% thermal conductivity gain in graphene cooling fluid
Haydale's graphene-based additive boosts thermal conductivity in glycol coolants by 28%, aligning performance with water while preserving glycol's protective properties. The company is expanding market partnerships and production capacity.
Haydale has announced advancements in the commercialization of its Super-Efficient Thermal Transfer Fluid, a graphene-based additive designed to enhance glycol coolants for data-center cooling systems. Since its launch last October, the additive has demonstrated an approximate 28% increase in the thermal conductivity of inhibited glycol, aligning its thermal performance with that of pure water while maintaining the freeze and corrosion protection of glycol-based coolants.
Live-silicon testing of the fluid showed thermal performance comparable to water, without any fouling or viscosity issues. Haydale indicated that this technology could enable data-center operators to boost compute density and lower cooling-related energy consumption as rack power and thermal loads rise. However, the company noted that these advantages are contingent on the additive's performance in commercial settings.
On the commercial front, Haydale has established supply-chain and market-entry agreements with Liquitherm and Levidian. The company is also in advanced discussions with data-center operators managing approximately 200 MW of capacity. Haydale's facility in Ammanford has the capability to treat about two million liters of coolant annually, which the company estimates could support the coolant needs of around 2 GW of data-center capacity.
The thermal fluid is part of Haydale's dual-product strategy following its restructuring, alongside the JustHeat underfloor heating platform. Both products utilize the company's HDPlas plasma-functionalization process for graphene materials.
