Automatic Changeover - Gas Supply Panel

An automatic gas changeover panel is designed to facilitate seamless changeover between two cylinder banks without interrupting gas flow. It utilizes two pre-set regulators operating on differential pressure to control the changeover process, ensuring continuous and stable gas delivery.

When the pressure in the active cylinder bank drops below the pre-set level, the system automatically switches to the standby cylinder bank. The changeover mechanism disengages the empty cylinder and activates the full cylinder bank, maintaining uninterrupted gas supply. Supplied ready for installation with all components pre-mounted on a panel, it is ideal for applications where continuous gas availability is critical.
