First Graphene’s PureGraph Suitable as Coolant

First Graphene (ASX:FGR) announced that its PureGraph is highly suitable as a coolant as initial testing confirm that it has enhanced production without compromising fluid performance.

As quoted in the press release:

As previously announced FGR agreed to supply PureGRAPH™ to test its suitability for use in car engine cooling to facilitate better fuel efficiency and reduced emissions. Further applications include coolants in electrified systems such as batteries and high-performance computing and data centres, so they can be charged faster with reduced capacity losses as well as improved cooling of high performance computing and data centres to reduce power consumption. The market size for heat transfer fluids in Australia was $3bn in 2016 and is expected to grow to $4.5bn by 2022. To date, whilst at the experimental scale, FlexeGRAPH has been sourcing its graphene under licence from the Canberra-based university. The opportunity existed for FGR to provide more economically priced largescale graphene supplies.

FlexeGRAPH has been trialling FGR’s PureGRAPH™ 5 as an input material in FlexeGRAPH’s proprietary process for the production of specialty heat transfer fluids. Initial laboratory based testing has confirmed the PureGRAPH™ 5 is a highly suitable component which has enhanced production throughput without compromising fluid performance. This has eliminated a potential production bottleneck leading to a rapid expansion in FlexeGRAPH’s fluid production volume capabilities. Current efforts are focussed on scaling batch sizes to 1,000L of heat transfer fluids incorporating PureGRAPH™ 5. Success in this area will lead to subsequent system testing with one of FlexeGRAPH’s downstream partners where superior thermal performance is a necessity.

Coolant Technology Being Developed by FlexeGRAPH

FlexeGRAPH has developed a family of fluids enhanced with graphene nanotechnology to replace existing water and glycol-based coolants and liquids used in heat transfer applications. These results in enhanced thermal conductivity and heat transfer with excellent stability, even at elevated operating temperatures.

The main areas of focus and the benefits achieved are currently;
a) Car engine cooling
i. enabling higher operating temperature
ii. reduced fuel consumption and emissions
iii. smaller radiators, pumps and fans

b) EV battery cooling
i. reduced charging times
ii. extended battery lifetime

c) HPC and data centre cooling
i. Reduced volume of cooling systems and energy consumed

d) Drilling and cutting fluids
i. Improved tool performance and component quality

Managing Director, Craig McGuckin, stated: “The results of the test work with FlexeGRAPH are further evidence of the suitability of FGR’s PureGRAPH™ products in a range of real-world applications. The performance improvements offered by PureGRAPH™ enhanced materials is being demonstrated repeatedly with our partners and customers. The consistent quality of the PureGRAPH™ products provides the end user with a confidence of a quality assured and proven product.”

FlexeGRAPH CTO Shannon Notley stated: “Consistent material quality from our value chain partners is of the utmost importance as we scale our heat transfer fluid production. FlexeGRAPH is pleased to be entering in the next phase of our testing with the confidence that PureGRAPH™ will provide a versatile material suitable for our bespoke coolant technology.
