Keep Your Chiller Running Properly with Regular Maintenance
LTD Analysis/Tube Cleaning
Increase chiller efficiency with tube inspection
Leaving Temperature Difference (LTD) analysis improves chiller performance and efficiency by verifying tube cleaning time and providing guidance to the customer for water quality management.
LTD Analysis
LTD lift is an index that indicates if the heat exchange performance of your tube cooler is deteriorating (LTD management criteria: below 3°C).
tube cleaning
Scale inside the heating tube interferes with heat transfer, reducing the life and efficiency of the device, therefore periodic cleaning is necessary.
benefit of
benefit of
Better performance and lower power consumption improve the reliability of your cooler (actual values for improvement may vary by site).
Ensure the reliability of the internal parts of the compressor.
Oil change and analysis
The replacement cycle is analyzed by oil differential pressure analysis and replaced with pure LG oil to ensure parts reliability. Oil analysis can be added upon customer request.
benefit of
PPrevention of damage to major components due to lack of lubrication
Propose suitable compressors for better operation
Discharge Overheat Analysis
Site load analysis by analyzing the number of times the upper and lower limits (3 - 10°C) of discharge superheat are reached.
Annual analysis of operating areas
Analysis of operating zones by chilled water temperature and cooling water inlet.
benefit of
Provide suitable compressor and stable operating environment to ensure reliability and energy saving. (A: Inverter, B: High Head Comp, C: High Capacity Chiller/High Head, D: High Capacity Chiller)
Prevent damage with early failure detection of rotating parts
Data-driven vibration analysis
Failure prediction through vibration trend analysis.
Note) A: Bearing oil temperature / B: Oscillation Vibration
Spectral analysis of vibrations
Fault prediction by Hz spectral analysis.
benefit of
Extend compressor life and reduce overhaul costs and downtime by preventing compressor failure.
Safe compressor integrity with surge prevention logic
Surge analysis
The moments of surges that occur in the compressor are analyzed.
Surge Prevention Logic Application
Overvoltages are prevented by resetting the self-learning surge lines.
Note) A: Early surge line / B: Actual surge line / C: Map surge line
benefit of
Prevention of damage to compressor components, energy reduction and stable operation of the product.
Improve heat exchanger performance and cooler integrity
Analysis of absorbent components
The analysis checks for absorbent alkalinity that can lead to scale development and checks for the proper amount of corrosion inhibitors.
absorbent purification
Purification of the absorbent solution by filter or ionic method.
benefit of
Energy saving and longer life of the cooler.
Extend the life of the heat exchanger and improve its efficiency
