Mitsubishi Motors applied THERMAL-XR® graphene coating to a split-type air conditioner at its site in Chonburi, Thailand, and measured a 9.17% reduction in energy use, translating to an estimated saving of 67,410 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 Mitsubishi Motors’ site in Chonburi, the split-type air conditioner is a Mitsubishi Electric unit with a capacity of 300,000 BTU.
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: 453.77 kWh/day before coating vs 412.16 kWh/day after
- Electricity cost: 61,259 THB/month before coating vs 55,642 THB/month after
- Carbon emissions: 74 tons CO2/year before coating vs 67 tons CO2/year after
- Annual saving: 67,410 THB per year
- ROI: < 2 years
These results equal an energy saving of 9.17%.
Takeaway
The Mitsubishi Motors case shows that coating existing split-type air conditioners can lower energy consumption and electricity costs at a large automotive site without replacing equipment.
