Chiller Renewal Service
Service to prevent secondary accidents and ensure product stability through regular compressor component replacement.
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 normalisation.
A service to prevent damage to key compressor components and to reduce energy consumption through reducing number of surge occurrences.
The time of surges occurred in the compressor are analysed.
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.
Leaving temperature differing (LTD) analysis improves chiller performance and efficiency through checking tube cleaning time and providing customer water quality management guide.
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).
Regular oil replacement improves the durability of core parts ensuring stable product management.
The replacement cycle is analysed 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
Air pollution can be reduced through replacement of Low-NOx burner that can inhibit the generation of nitrogen oxides (NOx) from combustion temperature and fuel.
Reduced nitrogen oxide(NOx) and improved combustion efficiency.
Increased combustion efficiency, reduced fuel costs, and improved air quality.
Services for improving heat exchange performance and extending its life time by decontaminating condenser cooling fins and preventing fin corrosion.
