An overcharged refrigerant system in an air-cooled chiller can lead to inefficient cooling, excessive pressure buildup, compressor failure, and increased energy consumption.
If not corrected, an overfilled refrigerant charge reduces system efficiency, causes overheating, and can damage key components.
EKG (Malaysia) Sdn Bhd provides comprehensive overcharged refrigerant troubleshooting, ensuring optimal chiller performance, energy efficiency, and long-term equipment reliability.
Our ISO-certified troubleshooting services cater to:
Industrial & Manufacturing Facilities
