Superior corrosion protection
We've tested THERMAL-XR® to 30,000+ hours of salt spray exposure (ASTM B117-19) with zero corrosion - protecting your assets and delaying replacement costs.
Coastal corrosion protection
THERMAL-XR® for coastal corrosion protection
For coastal resorts, hotels and businesses, salty air can accelerate air-conditioner corrosion, shorten asset life and make replacement costly, especially on high-rise buildings.

What is THERMAL-XR®
A graphene-powered coating system for air-cooled HVAC‑R equipment
THERMAL-XR® is an air-conditioning coating system powered by GMG Graphene. GMG frames it as a way to resist corrosion and rust by helping repel moisture, with a 5-year product warranty when regular six-month cleaning is maintained.
It is suitable for aluminium and copper fins and tubes used in air-cooled air-conditioning equipment, and can be applied to new or existing units on site without removing them from the building.
Resists corrosion, rust and moisture on exposed HVAC‑R surfaces.
Supports heat transfer and thermal efficiency in the coated system.
Helps extend service life where coastal corrosion drives replacement cost.
On-site application
Treat installed units without removing them from the building
THERMAL-XR® helps coastal operators extend unit life before replacement becomes necessary.
Why choose THERMAL-XR®
Three reasons to choose THERMAL-XR® for coastal HVAC‑R
The coastal-corrosion story is strongest when it stays practical: protect exposed coils, maintain heat transfer and reduce the pressure to replace equipment early.
Superior heat transfer
THERMAL-XR® heat-transfer performance is verified by the University of Queensland, helping reduce energy costs.
Cleanliness and water resistance
Our nanotechnology coating keeps HVAC‑R surfaces cleaner for longer and resistant to water.
Elements of Byron
A beachfront resort case for extending HVAC‑R unit life
Close to the ocean, this resort used to replace air conditioners because of corrosion. After we applied THERMAL-XR®, we expect 3-5 years of extra unit life.
Coastal corrosion costs more than looks – it affects capital planning, access costs and the timing of equipment replacement. THERMAL-XR® protects exposed HVAC‑R assets for hotels, resorts and coastal businesses, while keeping heat-transfer performance high.
