Chiller Annual Maintenance

Keep Your Chiller Running Properly with Regular Maintenance

LG Centrifugal Chiller unit, grey-toned assembly of circular and rectangular forms, adorned with red tags marking centrifugal, absorption, and screw.

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).
