I.P. One Co., Ltd., a Thai consumer goods manufacturer, applied THERMAL-XR® graphene coating to two air-cooled chillers and measured a 9.27% reduction in energy use, translating to an estimated saving of 184,198 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 I.P. One, the cooling load is carried by two Trane air-cooled chillers, each with a capacity of 48 tons, and they have been in service for 7 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 air-cooled chillers, with no change to the equipment itself.
Results
Energy use was compared before and after coating:
- Electricity usage: 1,512 kWh/day before coating vs 1,372 kWh/day after
- Electricity cost: 165,586 THB/month before coating vs 150,236 THB/month after
- Carbon emissions: 246 tons CO2/year before coating vs 223 tons CO2/year after
- Annual saving: 184,198 THB per year
- ROI: < 2 years
These results equal an energy saving of 9.27%.
Takeaway
The I.P. One case shows that coating existing air-cooled chillers can lower energy consumption and electricity costs without replacing equipment, even on relatively young units that have been running for 7 years.
