A substantial gray-toned LG Chiller unit commands attention in a machine-filled room, its presence accentuated by green/blue pipes.

Chiller Renewal Service

 

Optimize your chiller with the renewal service

A quarter of the chiller component is exposed, revealing a complex interior filled with intricate metallic parts.

Compressor parts overhaul

Secure compressor integrity for stable operation

Service to prevent secondary accidents and ensure product stability through regular compressor component replacement.

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 & prevention

Secure compressor integrity with surge prevention logic

A service to prevent damage to key compressor components and to reduce energy consumption through reducing number of surge occurrences.

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/Tube cleaning

Increase chiller’s efficiency with tube inspection

Leaving temperature differing (LTD) analysis improves chiller performance and efficiency through checking tube cleaning time and providing customer water quality management guide.

 

Note)
LTD(Cond.) = Cond. Ref. Temp. – Cooling Water Outlet Temperature
LTD(Evap.) = Chilled Water Outlet Temperature – Evap. Ref. Temp.

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 replacement

Securing reliability of the compressor’s internal parts

Regular oil replacement improves the durability of core parts ensuring stable product management.

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

Comply with regulations by replacing low-nox burner

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.

Low-nox burner replacement

Reduced nitrogen oxide(NOx) and improved combustion efficiency.

 

Benefit

Increased combustion efficiency, reduced fuel costs, and improved air quality.

Heat Exchanger Fin Cleaning

 

Extend heat exchanger life time and improve its efficiency

Services for improving heat exchange performance and extending its life time by decontaminating condenser cooling fins and preventing fin corrosion.
