Background
Air conditioning and chiller systems are among the largest electricity users on an industrial site, especially in food and supplement production where temperature and humidity must be tightly controlled. Over time, condenser coils lose heat transfer efficiency, which forces compressors to work harder and increases energy consumption. At Pronova Laboratories, the cooling load is carried by a Daikin air-cooled chiller with a capacity of 586 kW, which has 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 coating was spray-applied to the condenser coils of the air-cooled chiller, with no change to the equipment itself.
Results
Energy use was compared before and after coating:
- Electricity usage: 785 kWh/day before coating vs 654 kWh/day after
- Electricity cost: 105,968 THB/month before coating vs 88,356 THB/month after
- Carbon emissions: 128 tons CO2/year before coating vs 107 tons CO2/year after
- Annual saving: 211,343 THB per year
- ROI: < 2 years
These results equal an energy saving of 16.62%.
Takeaway
The Pronova Laboratories case shows that coating an existing air-cooled chiller can lower energy consumption and electricity costs without replacing equipment, even on a unit that has been running for 9 years.
