GM2-D series

Digital Automatic Manifold Systems

GM2-D series digital automatic manifold system is designed to provide an uninterrupted gas supply. The fully automatic digital manifold system monitors cylinder bank pressure electronically, automatically changes over to secondary bank when the primary cylinder bank is depleted, and eliminates the need to manually set a priority side. In case of power failure, the system continues to supply gas without interruption. Using our second generation pressure differential switchover valve and newly designed manifold regulators boosts the flowrate and reliability of the system.

Features

Automatic Changeover Cabinet

• Fully enclosed, tamper-resistant metal cabinet
