Industrial Automation
We build inspection and monitoring systems and dedicated hardware that tie PLCs, instruments, barcodes and MES together — from refrigerant gas leak testing and charge correction to smart factories and vacuum testers.
Industrial automation —
five solutions
From line inspection and quality control to production tracking — software and dedicated hardware together.
Currently supplied to a major Korean manufacturer, with 20+ installations at plants in about 7 countries.
Analyses every charge record to calculate per-model corrections and applies them via PLC.
Process output, testing, stock and shipping tracked in real time by QR and barcode.
A dedicated board and touch HMI measure vacuum to judge leaks.

Refrigerant gas leak detection system
System layout — two test positions, leak detectors, PLC, test PC and two monitors (installation at a plant in China)

Automatic refrigerant gas leak testing for air-conditioner production lines — currently supplied to a major Korean manufacturer, with 20+ installations at plants in about 7 countries. Each system is custom-developed and installed to fit the equipment and process of its production line.
- Custom development and installation for each production line
- PLC, test set and nozzle control with INFICON leak detectors
- Barcode scan linked to GMES model information
- Two-channel real-time charts with automatic OK/NG
- Result database, CSV export, alarm history, per-model parameters
- Operations board on a second monitor — daily stats, yield, channel status
Automatic testing that follows the line
- One PC and two monitors run two test positions at once
- Standby → detecting → cleaning runs automatically, with live graphs per channel
- Barcode read failures or NG results raise an alarm and stop the line
- A separate status board shows today's results and yield
Refrigerant charge correction system
Every record from the refrigerant charger is collected and stored, then analysed over a chosen period to calculate a correction value for each model. The values are sent to the PLC and applied to charging right away.
- Automatic collection of all charging and scale-calibration history
- Mean, standard deviation and process capability (Cp, Cpk) by period and model
- Per-model correction tables saved as dated files for traceability
- Live process capability and correlation for amount, pressure and time
Main screen — charging status, automatic correction history, per-model corrections
Before and after correction, side by side
Pick a period and model, and actual results are calculated next to the expected values after correction. Distribution curves and control limits for both make the effect clear before it is applied to the charging process.
QR- and barcode-based smart factory system
We connected a paper-based production floor with QR codes and barcodes. One scan per process sends plan-versus-actual output, performance-test results, stock and shipments to the server in real time and onto status boards.
- QR codes issued, attached and scanned per process for automatic output counts
- Test-room temperature, flow and current measured, with OK/NG recorded automatically
- Production, stock and shipping history in one database
- LED status boards on each line plus an office overview board
Process status program
Records progress by barcode scan per process, drives the status board and prints QR/barcode labels.
Performance test & shipping
Collects test data from instruments and manages results through to shipping-label printing.
Master data, schedule & stock
Models, specs, users, orders, production plans and stock in one place, with reports.
Overview board
Stock by model and process status by line on a large office display.
Vacuum decay tester
A tester that measures the vacuum level of refrigeration piping to judge leaks. A development case in which we built everything from the main board to the touch-screen software.
- Our own main board (SRM-400) measures vacuum sensors and controls the vacuum pump
- 12/24 V sensor power, photo-coupler inputs, RS422/485 and analog (ADC) sensors
- Reads product data by barcode (RS232) and stores it with the result
- Measurement history saved to USB and shared with other systems over RS485
From measurement to history, by touch
Set the time and set point, and the vacuum curve is drawn live; at the end the minimum, maximum and OK/NG are shown. Past results can be searched by date and operator and opened again.
