Alert - 2 SeriesAPPENDIX - OLiquid Cylinder ApplicationsThe Liquid by Liquid manifold is specifically designed to regulate and monitor vaporized gas from cryogenicliquid cylinders. The manifold incorporates special cryogenic regulators to prevent regulator freeze up underhigh-flow conditions. To prevent the loss of useful gas into the atmosphere, an economizer circuit is includedto utilize the accumulated excess pressure from the secondary supply bank. The economizer circuit reroutes theexcess pressure into the line via check valves inserted in the main inlet blocks, then passes through the 0.007”orifice which goes into the main centre section of the manifold. The Manifold shall be a digital, fully automatic type and shall switch from "Bank In Use" to "Reserve" bank withoutfluctuation in the supply line pressure and without the need for external power. After the switch-over, the"Reserve" bank shall then become the "Bank in Use" and the "Bank in Use" shall become the "Reserve" bank.When change-over occurs, the ‘Push to Test’ button must be pressed to re-set the manifold into “Ready” mode.The manifold will be powered by a microprocessor located behind the front door panel.Page: 45
