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
