Press Release TXR News, Installed & Tested



BRISBANE, QUEENSLAND, AUSTRALIA – Graphene Manufacturing Group Ltd. (TSX-V:GMG) (“GMG” or the “Company”) is pleased to release results of heat transfer demonstrations of Aluminium coated with THERMAL-XR® (TXR) powered by GMG Graphene, compared to uncoated bare Aluminium.

The University of Queensland Materials Performance consultancy (“UQMP”) verified that GMG’s THERMAL-XR® when applied to aluminium reduces the surface temperature by approximately 15% in temperatures between 70C and 90C.

GMG’s experiment results are shown below. The same 10mm thick aluminium plate was divided into two parts, GMG’s THERMAL-XR® was applied to the top side of one half of the plate, while the other remained uncoated. The same heat source was applied to the underside of both adjacent plates simultaneously. Temperature measurements were then taken from the top and bottom sides of both plates as the heat source was cycled up and down.

Managing Director and CEO, Craig Nicol stated “This is a powerful demonstration of GMG’s THERMAL-XR®’s ability to increase the transfer of heat. The graphene-enhanced heat transfer properties of THERMAL-XR® are apparently outweighing the traditional insulating effect of coatings. GMG believes the ability to increase heat transfer with a simple application of the technically advanced GMG THERMAL-XR® can make a significant contribution to improved performance and efficiency while reducing energy demand in a wide range of applications.”

When the THERMAL-XR® coating was applied to the top side of the 10mm aluminium plate, more heat transfer was observed away from the common heat source (compared to the panel that had no coating). Furthermore, the non-coated underside of the coated panel – being the side directly exposed to the heat source – remained approximately 15% cooler than the heat-exposed side of the uncoated panel, within the temperature range of 70° C to 90° C.


GMG’s product demonstration shows THERMAL-XR® coating increases heat transfer when applied to aluminium.

THERMAL-XR® powered by the GMG Graphene coating system is a unique method of improving the conductivity of heat exchange surfaces, resulting in an efficiency improvement and a potential power reduction when applied to air conditioning condenser coils or other industrial processes needing heat transfer.

The performance of existing air conditioners can also be increased with THERMAL-XR® process fluids (PREP and ACTIVATE) which clean and remove corrosion on the coil before applying the THERMAL-XR® RESTORE.

Relevance to Heat Exchangers (in Air Conditioners and Industrial Applications)


GMG is undertaking further assessments on other metals used in heat transfer applications and at various temperature settings and will publish market updates from time to time on these.

GMG is a proud member of Stanford University’s Thermal and Fluid Sciences Affiliates Program (see 10th May 2022 Announcement) and will continue to work with UQMP on heat transfer data verification.

GMG is working with a number of companies globally to engage distributors and direct sales for the HVAC-R maintenance market. Furthermore, GMG is engaging with various companies for direct selling of THERMAL-XR® for industrial applications with high energy requirements, and high emissions – including oil and gas production, power generation, liquified natural gas production, mining, and mineral processing.
