A substantial gray-toned LG Chiller unit commands attention in a machine-filled room, its presence accentuated by green/blue pipes.
Compressor Parts Overhaul
Surge Analysis & Prevention
LTD Analysis/Tube Cleaning
Oil Replacement
Low-NOx Burner Replacement
Heat Exchanger Fin Cleaning
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
Replacement of main parts of the compressor and motor.
Note) A: Bull Gear / B: Pinion Shaft / C: Bearing / D: Impeller
Prevent compressor failures and save energy through product efficiency and performance normalization.
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.
Note)
LTD(Cond.) = Cond. Ref. Temp. – Cooling Water Outlet Temperature
LTD(Evap.) = Chilled Water Outlet Temperature – Evap. Ref. Temp.
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).
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
Reduced nitrogen oxide(NOx) and improved combustion efficiency.
Increased combustion efficiency, reduced fuel costs, and improved air quality.
