    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
