Thermal-XR® HVAC Coating System
Thermal-XR® HVAC Coating System is a unique method of improving the conductivity of corroded heat-exchange surfaces and maintaining the performance of new units at peak levels.
The process coats and protects heat-exchange surfaces while improving and rebuilding the lost corroded thermal conductivity and increasing the heat-transfer rate by leveraging the physics of GMG Graphene — resulting in an efficiency improvement and a power reduction.
Thermal-XR® can also protect both RTPF coils (round tube plate fin) and MCHC coils (microchannel) from accelerated corrosion damage, thereby extending the life of the coil and reducing energy consumption. GMG is developing specific formulations of Thermal-XR® for different industry applications and conditions.

Who needs
Thermal-XR®?
Heat exchangers are used in numerous industries wherever metal heat-exchange surfaces are required. Thermal-XR® has been used in industrial, commercial and residential applications.
- HVAC-R
- LNG & gas plants
- Oil & gas upstream
- Energy & power producers
- Refineries & petrochemical plants
- Chemical, heavy & mining industry
Why it matters
How Thermal-XR® benefits your business
Corrosion protection
GMG Graphene creates an impervious layer that prevents oxygen from reaching the metal surface, eliminating corrosion. Graphene's water repellency increases protection further.
Thermal emissivity
Graphene increases the heat emissivity of aluminum by a factor of 8,6.
Energy savings
Improved heat transfer helps reduce compressor operation times, leading to lower energy consumption.

Frequently asked questions
What results will I expect?
The results vary subject to the climate, age and deterioration of the equipment, cleanliness of the equipment, heating and cooling load, and the health of the equipment.
Will a black paint absorb sun radiation and become hotter?
Thermal-XR® is powered by GMG Graphene and leverages graphene to remove heat, whereas black pigment in most black paints absorbs and retains heat. Thermal-XR® works like a heat pump to transfer heat, whereas black paint typically performs as a paint insulator to retain heat in the paint and the substrate it is applied to.
How does Thermal-XR® affect my equipment warranty?
Each jurisdiction has Consumer Protection Laws, and no company or product is excluded from this protection.
Most HVAC-R equipment warranties contain an exclusion clause related to corrosion and weather influence (for example, damage due to corrosive atmospheric conditions such as sea air), and warranties are typically limited by component. Many OEMs recommend coil-coating protection.
Thermal-XR® carries its own conditional warranty on heat transfer and energy savings. Contact us for the full warranty terms for your equipment.
Is the specific Thermal-XR® coating for different industries?
Thermal-XR® is formulated for HVAC and other heat exchangers in industrial applications.
