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 Capsule Products, the cooling load is carried by Carrier air-cooled chillers with a capacity of 600,000 BTU, which have been in service for 14 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 air-cooled chillers, with no change to the equipment itself.
Results
Energy use was compared before and after coating:
- Electricity usage: 2,294.84 kWh/day before coating vs 2,088.02 kWh/day after
- Electricity cost: 279,084 THB/month before coating vs 254,050 THB/month after
- Carbon emissions: 373 tons CO2/year before coating vs 340 tons CO2/year after
- Annual saving: 300,406 THB per year
- ROI: < 1 year
These results equal an energy saving of 8.97%.
Takeaway
The Capsule Products case shows that coating existing air-cooled chillers can lower energy consumption and electricity costs without replacing equipment, paying for itself in under a year even on units that have been running for 14 years.
