BTicino, the Italian electrical equipment and smart home manufacturer owned by the Legrand Group, applied THERMAL-XR® graphene coating to a split-type air conditioner at its site in Thailand and measured an 11.24% reduction in energy use, translating to an estimated saving of 116,536 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 BTicino’s site in Thailand, the split-type air conditioner is a Carrier unit with a capacity of 200,000 BTU, and it has been in service for 12 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: 576 kWh/day before coating vs 511 kWh/day after
- Electricity cost: 86,400 THB/month before coating vs 76,689 THB/month after
- Carbon emissions: 94 tons CO2/year before coating vs 83 tons CO2/year after
- Annual saving: 116,536 THB per year
- ROI: < 2 years
These results equal an energy saving of 11.24%.
Takeaway
The BTicino 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 12 years.
