Liquid x Liquid Dewar Manifold
The automatic changeover liquid x liquid x high pressure reserve manifold is designed to provide a reliable uninterrupted supply of gas to a hospital or clinic’s medical gas pipeline system. It is designed to meet NFPA 99 type 1 facility requirements.
The automatic changeover manifold system consists of a manifold control with two supply bank headers, one service and one secondary supply to provide an uninterrupted supply of gas for the specific gas application. The manifold control includes the following components and features: inlet safety relief valves, green “system normal” and red “replace depleted cylinders” indicator lights, inlet pressure gauges, an economizer bypass check valve, and line pressure gauge. The control unit shall automatically switch to the secondary bank when the service bank is depleted. When the depleted cylinders are replaced with full cylinders, the operator should then turn the control knob to the opposite cylinder bank. This will make the partially used “Secondary bank” the “Service” supply and the newly installed cylinders will become the “Secondary “ supply.
