Chiyoda Seiki MCHP-100A Semi-automatic Switching Gas Supply Device Stand Set (standard flow rate: 50ℓ/min・Air) (for acetylene)

Made in Japan
Manufacturer: Chiyoda Seiki
Model: MCHP-100A

Feature

Our semi-automatic switching device facilitates gas collection from two container lines, A and B. Each line is equipped with two regulators connected in parallel. By adjusting the secondary pressure and adding a differential pressure, gas flows from the container line with the higher set value initially. As gas depletes in one container line, the device automatically switches to maintain continuous flow from the other line.

To replace an empty container in line A, filled with gas, and switch to line B, rotate the lever or adjust the handle to increase the secondary pressure in line B. This ensures stable gas supply from line B. When gas is low in line B, it automatically switches back to line A. Similarly, repeating this process enables continuous gas supply by maintaining stable pressure between the two lines.

In addition, by installing a pressure gauge with a lower limit contact on the primary side and connecting it to the alarm panel, the gas supply line can be switched. A buzzer and patrol lamp inform you of the situation, so it is convenient for container replacement.
