CKD Corporation, a Japanese manufacturer of automated machinery and pneumatic control components, applied THERMAL-XR® graphene coating to a split-type air conditioner at its site in Thailand 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 is a steady electricity cost across offices and production areas. Over time, condenser coils lose heat transfer efficiency, which forces compressors to work harder and increases energy consumption. At CKD’s site in Thailand, 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 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: 19 kWh/day before coating vs 16 kWh/day after
- Electricity cost: 2,591 THB/month before coating vs 2,257 THB/month after
- 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 THERMAL-XR® delivers double-digit savings even on small, everyday split-type units, so the same approach can be rolled out across every air conditioner on a site.
