SCG Packaging (SCGP), a leading multinational packaging solutions provider in Southeast Asia, applied THERMAL-XR® graphene coating to a split-type air conditioner at its Wang Sala No.2 site in Thailand and measured an 11.06% reduction in energy use, translating to an estimated saving of 96,478 THB per year and a return on investment of under 1 year.

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 SCGP’s Wang Sala No.2 site, the split-type air conditioner is a Uni-Air unit with a capacity of 200,000 BTU, and it has been in service for 3 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 the split-type air conditioner, with no change to the equipment itself.
Results
Energy use was compared before and after coating:
- Electricity usage: 509.91 kWh/day before coating vs 453.49 kWh/day after
- Electricity cost: 72,662 THB/month before coating vs 64,622 THB/month after
- Carbon emissions: 83 tons CO2/year before coating vs 74 tons CO2/year after
- Annual saving: 96,478 THB per year
- ROI: < 1 year
These results equal an energy saving of 11.06%.
Takeaway
The SCGP case shows that coating split-type air conditioners can lower energy consumption and electricity costs without replacing equipment, paying for itself in under a year even on new units that have been running for only 3 years.
