TGCS (TED Gas Control System)
We have engaged in designing and development for dryer facilities under the theme of “energy-saving” and “safety”. To maximize energy savings in drying processes, the most effective approach is to increase the drying exhaust recycling rate, thereby reducing the energy consumed by the heat source.
In order to increase the recycling rate of dryer exhaust, we developed the "TED Gas Control System (TGCS)" in 1990. a system that system ensures explosion-proof safety of dryer equipment. This system uses an interferometric gas concentration meter, which is not affected by sensitivity degradation even with high-concentration dryer exhaust, to detect gas concentration in real time and automatically controls the exhaust to maintain a safe concentration level set at 25% LEL.
Furthermore, the TGCS allows dryer exhaust to be processed at higher concentration and lower flow rates, enabling downsizing of exhaust gas treatment equipment, reducing auxiliary fuel consumption through improved self-sustaining combustion rates, and when waste-heat boilers are installed, increasing the recovered steam.
In addition, by integrating ancillary and energy-saving equipment, the system can significantly reduce the total installation cost of an energy-efficient exhaust gas treatment system.
Moreover, we have developed feed-forward control synchronized with production machine behavior, as well as a temperature control compensation function that prioritizes drying temperature stability. The system continues to evolve to ensure both safety and production stability.

Features of Optical Interferometric Gas Analyzer
| Compact & Low Cost | Compared to the conventional models, this is more compact and cost-effective. |
|---|---|
| Long Service and Maintenance-Free | Measurements use Fourier Transform Optical Interferometry. An optical interferometry sensor shows no sensitivity deterioration. Using LED as a light source, and CCD as a detector minimizes deterioration. |
| No sensitivity degradation | Non-contact measurement ensures zero sensitivity degradation caused by coexisting substances such as silicone. |
| Additional features | Various functions, such as temperature and pressure compensation via a built-in microprocessor. |
| Control function | The digital controller is equipped with a dedicated programs that enable PID and feedforward control to predict transient increases in concentration. It also features a temperature compensation function that prioritizes stable drying temperature control on machines. |
| Self-diagnostic function | ・Flow Alarm – Pump deterioration or filter clogging ・Light Source Alarm – Light source degradation or drying chamber contamination ・Contrast Error Alarm – Dirty in drying chamber or CCD degradation |
| Quick response | A quick response is achieved thorough continuous sampling method. |
| No warm up operation | No warm-up operation is required. |
| Minimal sensitivity variation | Minimal sensitivity variation across different target gases simplifies recalibration and setup. Also ideal for mixed solvents. |
