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).
Scales inside the heat tube interfere with heat transfer, reducing the life time and efficiency of the device, so regular cleaning is required.
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.
Prevention of damage to core components due to lack of lubrication
Discharge Superheat Analysis
Site load analysis by analyzing the number of times the upper and lower limits (3 - 10°C) of the discharge superheat are reached.
Annual Operating Zone Analysis
Analysis of operating zones by temperature of chilled water and cooling water inlet.
Propose suitable compressor and stable operating environment to secure the reliability of it and energy save. (A:Invertor, B:High Head Comp., C: Large Capa./High Head Chiller, D: Large Capa.Chiller)
Data-based Vibration Analysis
Failure Prediction through vibration trend analysis.
Note) A : Bearing Oil Temperature / B : Oscillation Vibration
Spectral Vibration Analysis
Prediction of failure through Hz spectral analysis.
Extension of compressor life time and reduction of overhaul costs and downtime through avoiding compressor failure.
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
Prevention of compressor components damage, energy reduction, and stable product operation.
Absorbent Component Analysis
The analysis checks absorbent alkalinity which can lead to the development of scale and checks appropriate amount of corrosion inhibitors.
Purification of absorbent solution by filter or ionic method.
Energy savings and extension of chiller life time.
