BioNet-Asia Co., Ltd. (BioNet), a Thai-French biotechnology group that discovers, develops and manufactures next-generation vaccines, applied THERMAL-XR® graphene coating to two split-type air conditioners and measured a 15.73% reduction in energy use, translating to an estimated saving of 7,551 THB per year and a return on investment of under 2 years.

Background
Air conditioning is a constant electricity cost in biotechnology facilities, where labs and production areas need stable, controlled temperatures. Over time, condenser coils collect dust and lose heat transfer efficiency, which forces compressors to work harder and increases energy consumption. At BioNet, two Daikin split-type air conditioners, each with a capacity of 24,000 BTU, have 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 coils were cleaned and the coating was spray-applied to the condenser coils of both split-type air conditioners, with no change to the equipment itself.
Results
Energy use was compared before and after coating:
- Electricity usage: 28.07 kWh/day before coating vs 23.66 kWh/day after
- Electricity cost: 4,000 THB/month before coating vs 3,371 THB/month after
- Carbon emissions: 4.57 tons CO2/year before coating vs 3.85 tons CO2/year after
- Annual saving: 7,551 THB per year
- ROI: < 2 years
These results equal an energy saving of 15.73%.
Takeaway
The BioNet case shows that coating existing split-type air conditioners can lower energy consumption and electricity costs in a biotechnology facility without replacing equipment, even on units that have been running for 9 years.
