Samut Prakan Hospital, the main regional hospital in Samut Prakan Province, Thailand, applied THERMAL-XR® graphene coating to two split-type air conditioners and measured a 12.56% reduction in energy use, translating to an estimated saving of 24,556 THB per year and a return on investment of under 2 years.

Background
Air conditioning is one of the largest electricity users in a hospital, where cooling runs around the clock to keep patients and staff comfortable. Over time, condenser coils lose heat transfer efficiency, which forces compressors to work harder and increases energy consumption. At Samut Prakan Hospital, two Carrier split-type air conditioners, each with a capacity of 36,000 BTU, have been in service for 3 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 split-type air conditioners, with no change to the equipment itself.
Results
Energy use was compared before and after coating:
- Electricity usage: 119.03 kWh/day before coating vs 104 kWh/day after
- Electricity cost: 16,292 THB/month before coating vs 14,246 THB/month after
- Carbon emissions: 19 tons CO2/year before coating vs 17 tons CO2/year after
- Annual saving: 24,556 THB per year
- ROI: < 2 years
These results equal an energy saving of 12.56%.
Takeaway
The Samut Prakan Hospital case shows that coating split-type air conditioners can lower energy consumption and electricity costs in healthcare facilities without replacing equipment, even on new units that have been running for only 3 years.
