Faster heat transfer
THERMAL-XR® restores heat transfer across HVAC‑R coil surfaces.
Coil protection
Protects aluminium and copper heat exchange surfaces against corrosion.
Energy savings
Restored thermal performance reduces operating demand, confirmed by independent testing.
Retrofit path
THERMAL-XR® is applied to existing assets on-site with no equipment replacement required.
Commercial coating system
Coating for HVAC‑R heat exchangers
THERMAL-XR® is a graphene-enhanced coating for aluminium and copper air-cooled heat exchangers, corroded or new, where heat transfer, corrosion protection and energy use are connected. Measured across commercial buildings, data centres, hospitals and industrial plant in Australia, Singapore, Thailand, the USA and Romania.

Product system
THERMAL-XR®: how the system works
ENHANCE is a water-based acrylic resin coating containing thermally conductive GMG graphene. Application is completed on-site by GMG-certified applicators. Developed and manufactured in Australia.
Application fit
Built for air-cooled heat exchange equipment
For air conditioning and refrigeration coils, including RTPF and microchannel formats.
Designed to coat and protect heat exchange surfaces while supporting thermal conductivity.
Relevant to commercial, industrial and residential cooling applications.
THERMAL-XR® is backed by independent testing, corrosion-resistance data, U.S. EPA approval and full application documentation.
Independent testing
UQ-verified heat transfer and energy saving results
THERMAL-XR® heat transfer and energy saving results are independently verified by the University of Queensland.
Protection
Independently tested corrosion resistance
20,000+ hours ASTM B117 salt spray resistance, tested by Industrial Inspection & Analysis.
Market access
U.S. EPA approval opens a larger commercial channel
THERMAL-XR® carries U.S. EPA approval for sales in the United States.
Documents

SDS, PDS and application materials help procurement, facilities and partner teams review the product before installation.
Buyer questions
Common questions from facilities and HVAC‑R buyers
Is THERMAL-XR® for new equipment or existing assets?
THERMAL-XR® is designed for existing air-cooled heat exchangers where surface condition, corrosion and energy use are already visible issues.
Who applies the product?
Installation follows product documentation and local requirements. GMG applicator and distributor network connects operators with the right installation support.
Does THERMAL-XR® guarantee a fixed energy saving?
No. Energy outcomes depend on asset condition, environment, installation quality and operating profile. GMG provides testing, mechanism explanations and product documentation for evaluation.
Where can a buyer go next?
A buyer can review product information, open the THERMAL-XR® store, contact GMG about an application, or connect with an applicator or distributor.
Is THERMAL-XR® just a black coating?
No. THERMAL-XR® is a graphene-enhanced coating that improves thermal conductivity and protects surfaces, not a conventional black paint that absorbs and holds heat.
What warranty does THERMAL-XR® carry?
THERMAL-XR® is backed by a 5-year limited warranty, with a recommended 6-monthly maintenance schedule.
Can THERMAL-XR® be applied to microchannel coils as well as RTPF?
Yes, THERMAL-XR® supports both RTPF and microchannel formats.
How is THERMAL-XR® applied?
THERMAL-XR® can be applied by spray applicator, flow coat or dipping. Typical on-site application takes 1-2 days.
