CKD in Thailand applied THERMAL-XR® graphene coating to its split-type air conditioner and measured a 12.88% reduction in energy use, translating to an estimated saving of 4,004 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 CKD, the split-type air conditioner is a Mitsubishi Electric unit with a capacity of 18,000 BTU, and it has been in service for 9 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 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: 19 kWh/day before coating vs 16 kWh/day after
- Electricity cost: 2,591 THB/month before coating vs 2,257 THB/month after
- Carbon emissions: approximately 3 tons CO2/year (rounded), with the energy reduction lowering emissions over time
- Annual saving: 4,004 THB per year
- ROI: < 2 years
These results equal an energy saving of 12.88%.
Takeaway
The CKD 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 9 years.
