Sahaviriya Steel Industries Public Company Limited (SSI), a major Thai producer of hot-rolled steel, applied THERMAL-XR® graphene coating to five split-type air conditioners and measured an 11.42% reduction in energy use, translating to an estimated saving of 96,966 THB per year and a return on investment of under 2 years.

Background
Air conditioning and chiller systems are among the largest electricity users on an industrial site. Over time, condenser coils lose heat transfer efficiency, which forces compressors to work harder and increases energy consumption. At SSI, five Carrier split-type air conditioners, each with a capacity of 120,000 BTU, have been in service for between 14 and 22 years.
The solution: THERMAL-XR®
THERMAL-XR® is a graphene-enhanced coating from Graphene Manufacturing Group (GMG), designed to deliver superior heat transfer and protection for heat exchanger coils. The coating was spray-applied to the condenser coils of all five split-type air conditioners, with no change to the equipment itself.
Results
Energy use was compared before and after coating:
- Electricity usage: 590 kWh/day before coating vs 522 kWh/day after
- Electricity cost: 70,757 THB/month before coating vs 62,676 THB/month after
- Carbon emissions: 95 tons CO2/year before coating vs 84 tons CO2/year after
- Annual saving: 96,966 THB per year
- ROI: < 2 years
These results equal an energy saving of 11.42%.
Takeaway
The SSI case shows that coating existing split-type air conditioners can lower energy consumption and electricity costs without replacing equipment, even on units that have been running for up to 22 years in a heavy industrial environment.
