Western Innovator LC Manifolds are designed to regulate and monitor vaporized gas from cryogenic cylinders. Convenient and easy to use, the system automatically changes over when the primary cylinder bank is depleted. Simply rotate the control lever to reset the unit. A self-contained alarm system alerts the user to the system's current status. A green light indicates the service bank is functioning and the reserve bank is ready for service. A red light signals that the system has changed over and one or both banks are depleted.
