Thai Cold Rolled Steel Sheet Public Company Limited (TCRSS), a Thai producer of cold-rolled steel sheet, applied THERMAL-XR® graphene coating to two split-type air conditioners and measured an 11.63% reduction in energy use, translating to an estimated saving of 84,671 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, and the dust and heat of a steel mill make condenser coils foul faster. Over time, those coils lose heat transfer efficiency, which forces compressors to work harder and increases energy consumption. At TCRSS, two split-type air conditioners from Carrier and Uni-Air, each with a capacity of 140,000 BTU, have been in service for 10 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 both units, with no change to the equipment itself.
Results
Energy use was compared before and after coating:
- Electricity usage: 631 kWh/day before coating vs 558 kWh/day after
- Electricity cost: 60,670 THB/month before coating vs 53,614 THB/month after
- Carbon emissions: 103 tons CO2/year before coating vs 91 tons CO2/year after
- Annual saving: 84,671 THB per year
- ROI: < 2 years
These results equal an energy saving of 11.63%.
Takeaway
The TCRSS case shows that coating existing split-type air conditioners can lower energy consumption and electricity costs across different equipment brands, even on units that have been running for 10 years in a steel-mill environment.
