GMG’s TXR coating system reduces surface temperature of heated aluminium by 15%, says UQMP

The amazing outcomes of heat transfer demonstrations for aluminium coated with THERMAL-XR (TXR) driven by GMG Graphene, as compared to uncoated bare aluminium, have been provided by the Australia-based cleantech company, Graphene Manufacturing Group Ltd (GMG).

The business claimed that GMG's THERMAL-XR decreases the surface temperature of aluminium by around 15 per cent at temperatures ranging from 70°C to 90°C. This claim was verified by the University of Queensland Materials Performance Consulting (UQMP).

A 10-millimetre (mm) thick aluminium plate was split in two during an experiment. One half of the plate was coated with GMG's THERMAL-XR, while the other was left untreated. The undersides of the two neighbouring plates were then both heated at the same time. According to the business, temperature readings were obtained from both plates' top, and bottom edges during the experiment as the heat source cycled up and down.

"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 THERMAL-XR can make a significant contribution to improved performance and efficiency while reducing energy demand in a wide range of applications," said Craig Nicol, CEO of Graphene Manufacturing Group.

More heat transfer was seen away from the common heat source when the THERMAL-XR coating was applied to the top surface of the 10 mm aluminium plate (compared to the panel with no layer). The business also found that, between the temperatures of 70° C and 90° C, the non-coated underside of the coated panel, which was the side immediately exposed to the heat source, stayed around 15 per cent cooler than the heat-exposed side of the uncoated board.

When used for air conditioning condenser coils or other industrial processes requiring heat transfer, THERMAL-XR driven by the GMG Graphene coating technology is a novel approach to increasing the conductivity of heat exchange surfaces, resulting in efficiency and potentially reducing power consumption.

The company stated that THERMAL-XR process fluids (PREP and ACTIVATE), which "clean and remove corrosion on the coil" before applying THERMAL-XR RESTORE, may also "improve" the performance of current air conditioners. GMG stated that it is examining additional metals used in heat transfer applications and at various temperature ranges and would periodically inform the market of its findings.

To engage distributors and direct sales for the HVAC-R maintenance industry, the company is collaborating with many businesses throughout the globe. Additionally, it collaborates with enterprises to direct-sell THERMAL-XR for industrial uses with significant energy needs and emissions, including mineral processing, liquefied natural gas production, mining, and oil and gas extraction.
