Keep your chiller running properly with regular maintenance

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

Site load analysis by analyzing the number of times the upper and lower limits (3 - 10°C) of the discharge superheat are reached.

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)

Failure prediction through vibration trend analysis.
Note) A : bearing Oil temperature / B : oscillation vibration

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.

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.

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.
