Machinery and metalworking

Ulsan · Parts machining, Companies A, B and C

3 plants

Challenge

There was no basis for comparing energy use across the three plants in the same region.

Setup

Core installed on each plant's main distribution panel and on its main machining equipment

Result

With machining equipment and air compressor loads measured separately, the customer identified which compressor run times to adjust. The three plants are compared on one screen.

Plastics and auto parts

Gyeonggi · Urethane foaming and injection molding, Company D

1 plant

Challenge

Mold heaters and cooling chillers ran 24 hours a day, so the base load was high.

Setup

Core installed on the distribution panels of the injection line and the foaming line

Result

The customer identified the load left running during non-production hours, and a ranking of use by equipment made it possible to set inspection priorities.

Paper and finishing

Jeonbuk · Corrugated boxes, Company E

1 plant

Challenge

The relationship between equipment operation and the electricity bill was hard to grasp.

Setup

Measurement points set up on the printing press, die cutter and box-making lines

Result

Use per equipment became visible, giving the customer a basis for rescheduling work during peak hours.

Textiles

Daegu · Towel manufacturing, Company F

1 plant

Challenge

Drying and heat treatment equipment accounted for most of the energy use.

Setup

Separate measurement of the loom, drying equipment and compressor lines

Result

The periods where peaks clustered around shift changes became clear, so the customer could stagger equipment start times.

Food manufacturing

Jeonbuk · Kimchi manufacturing, Company G

1 plant

Challenge

The low-temperature fermentation rooms and cold storage ran 24 hours a day, giving the site a base-load structure.

Setup

Core installed on the refrigeration unit, cold storage and packaging line circuits

Result

The customer monitors refrigeration run patterns continuously, receives early alarms on signs of trouble, and uses the base-load level as a management reference value.

Auto repair, multi-site

Nationwide in Korea · Auto repair network

22 sites

Challenge

Each shop differed in size and equipment, so there was no basis for judging whether its electricity bill was reasonable.

Setup

Core installed on each shop's distribution panel, with central monitoring from head office

Result

The customer compares use by shop on one screen and inspects the shops with high standby power outside business hours.

Electronics and semiconductor equipment

Chungnam · Equipment manufacturing, Company H

1 plant

Challenge

Process power equipment and HVAC loads were measured together and could not be separated.

Setup

Separate measurement of the process equipment circuits and the HVAC circuits

Result

The customer tracks power changes during test runs and manages the HVAC load on its own.

Wood processing

Jeonnam · Sawmilling and wood processing, Company I

1 plant

Challenge

The dust-collection blower ran at all times, consuming power even during non-production hours.

Setup

Separate measurement of the sawmilling equipment and the dust-collection and drying circuits

Result

The customer identified the periods running unnecessarily and also monitors signs of equipment trouble.

※ The ‘After deployment’ text in the cases above describes the operational improvements that AI-ELEX made possible. Savings in cost and percentage vary with site environment, equipment configuration and operating conditions. The photos were taken at actual installation sites and do not correspond one to one with each case. For existing buildings, a 5–15% reduction in annual electricity costs can be expected, and more where there is wide scope for operational optimization.
