Overhaul Timing
LG's recommended overhaul time is based on two years or 10,000 hours of driving.
Note) A: Initial Failure / B: Stability / C: Wear Failure
Major Part Replacement
Replacement of main parts of the compressor and motor.
Note) A: Bull Gear / B: Pinion Shaft / C: Bearing / D: Impeller
Benefit
Prevent compressor failures and save energy through product efficiency and performance normalization.
Surge Analysis
The time of surges occurred in the compressor are analyzed.
Surge Prevention Logic Application
Surges are prevented by resetting self-learning surge lines.
Note) A: Early Surge Line / B: Real Surge Line / C: Map Surge Line
Benefit
Prevention of compressor components damage, energy reduction, and stable product operation.
LTD Analysis
LTD lift is an index that shows whether the heat exchange performance of your chiller’s tube is deteriorating (LTD Management Criteria: Below 3°C).
Tube Cleaning
Scales inside the heat tube interfere with heat transfer, reducing the life time and efficiency of the device, so regular cleaning is required.
Benefit
Better performance and reduced energy consumption improve your chiller's reliability (Actual improvement values may vary by site).
Oil Change and Analysis
The replacement cycle is analyzed through oil differential pressure analysis and replaces it with LG pure oil to secure reliability of parts. Analysis of oil can be added upon customer request.
Benefit
Prevention of damage to core components due to lack of lubrication
Low-NOx Burner Replacement
Reduced nitrogen oxide(NOx) and improved combustion efficiency.
Benefit
Increased combustion efficiency, reduced fuel costs, and improved air quality.
