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.
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.

Why it matters
Why facilities teams choose THERMAL-XR®
Coil condition affects energy use, asset life and maintenance cost. THERMAL-XR® addresses all three.
Thermal performance
Recover performance at the surface
10-50% energy reduction measured across commercial HVAC, chillers and data centres.
Asset protection
Protect exposed metal coils
30,000+ hours salt spray resistance (ASTM B117-19), independently tested.
Energy logic
Reduce compressor workload
When heat transfer improves, cooling equipment can spend less time fighting thermal losses, supporting lower energy use.
Retrofit
Treat existing HVAC‑R assets
Extends coil service life, deferring capital replacement by years.
Surface area
Use micro surface area in a thin layer
Up to 300 m2 of micro surface area per gram of graphene supports heat dissipation inside the coating.
Application support
From product to qualified installation
On-site installation by GMG-certified applicators.
Where it fits
Built for cooling assets where heat loss becomes business cost
THERMAL-XR® is designed for air-cooled heat exchangers in demanding environments where coil condition drives operating cost.

Buyer questions
Common questions from facilities and HVAC‑R buyers
Is THERMAL-XR® for new equipment or existing assets?
Both. THERMAL-XR® restores lost heat transfer on corroded existing coils and maintains new equipment at peak performance. Existing assets – where corrosion and rising energy use are already visible – are the most common starting point.
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. Black pigment in conventional paints absorbs and retains heat, acting as an insulator. THERMAL-XR® does the opposite – its graphene works like a heat pump, moving heat away from the coil surface while protecting the metal underneath.
What warranty does THERMAL-XR® carry?
THERMAL-XR® carries a 5-year conditional warranty. Coverage requires installation by an accredited applicator and a 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.
