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.

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.

Why it matters

Why facilities teams evaluate 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), independently tested by Industrial Inspection & Analysis.

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?

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.
