Chiyoda Seiki MCH-100A Semi Automatic Switching Gas Supply Device Stand Set
Made in Japan
Manufacturer: Chiyoda Seiki
Model: MCH-100A
Features
The semi-automatic switching device uses two parallel regulators to alternate between gas lines A and B. As line A runs low, the system maintains flow and immediately switches to line B. Operators can control switching by rotating a lever (for CH-100, SC-15-B, LC-140) or adjusting a handle (for CH-140). This action boosts pressure in line B over A, ensuring a smooth and stable supply. When line B depletes, the system switches back to A. To keep gas flowing, users simply replace empty containers and operate the switch. Additionally, installing a pressure gauge with a lower-limit contact and linking it to an alarm triggers a buzzer and lamp, making container replacement more convenient and efficient.
