  • Page 9 INSTRUCTION MANUAL LIQUID CYLINDER GL-SERIES Flow Diagram  Liquid Fill and Withdrawal Valve Liquid product is filled into or withdrawn from the container through the connection controlled by this valve. It is equipped with a connection (CGA fitting) specifically required for the liquid service, for which the container is configured. If the liquid service changes, this connection must be changed as well.

  • Page 11 INSTRUCTION MANUAL LIQUID CYLINDER GL-SERIES Vaporizer Performance Graph  Pressure Building Coil A pressure building circuit is used to ensure sufficient driving pressure during high withdrawal periods. The function is actuated by opening the pressure building valve that creates a flow from the bottom of the container, through the pressure building coil, the regulator into the gas space in the top.
  • Page 12 INSTRUCTION MANUAL LIQUID CYLINDER GL-SERIES Pressure Building Rate Graph  Economizer An economizer circuit withdraws gas preferentially from the head space over the liquid in the container-gas that otherwise lost to venting. Excess pressure in the head space of the container is relief by allowing gas to flow from this area directly to the gas withdrawal (use) valve outlet while gas is withdrawn from the container;...

    INSTRUCTION MANUAL LIQUID CYLINDER GL-SERIES Caution: Internal orifices in pressure regulators used with CO2 are subject to the formation of dry ice if excessively cold gas or high flow rates are used. If this condition occurs, an external vaporizer should be used to ensure the gas is warmed before it reaches the regulator.

  • Page 16 INSTRUCTION MANUAL LIQUID CYLINDER GL-SERIES Pressure Transfer Filling Filling a liquid cylinder using the pressure transfer method is common for 22 psig (1.5 bar/152 kPa) service where the product is used for refrigerant purposes. This method may also be used for higher pressure cylinders to increase liquid holding time.
  • Page 17 INSTRUCTION MANUAL LIQUID CYLINDER GL-SERIES CAUTION: With carbon dioxide, pressure in the container being filled must be above 70 psig (4.8 bar/483 kPa) before the fill begins and at all times during the fill to prevent the product from freezing into dry ice. Pump Transfer Filling Method When a pump is used for filling liquid containers, the fill may be accomplished through either the VENT valve or LIQUID valve.
  • Page 18 Fill Rhrough Vent Valve Fill Hose Taylor-Wharton fill hose for these cylinders is designed to transfer specific liquefied gases to, or from, the containers. Cryogenic transfer hoses are constructed of stainless steel for the transfer of cryogenic liquids and are available in six feet (1.8 m) lengths with 3/8 in.

  • Page 19: Repair And Maintenance

    Pressure in the container must be maintained above this value to ensure a solid block of CO will not form inside the container. Before performing maintenance on an XL-45HP/50HP/55HP/50VHP/55VHP in service, the contents must be transferred to another container so that container pressure can be released.

    INSTRUCTION MANUAL LIQUID CYLINDER GL-SERIES 11. Change of Gas Service These cylinders may be converted from one service to another within the confines of the services for which the containers are designed if a change of gas service should be desired. For this conversion, the connection fittings on the pipes must be exchanged, further the scale on the liquid level gauge as well as product decals.

  • Page 24: Checking Container Performance

    INSTRUCTION MANUAL LIQUID CYLINDER GL-SERIES 14. Checking Container Performance The cryogenic container consists of two containers, one inside the other. The space between the containers acts as a highly efficient thermal barrier including high technology insulation, a vacuum, and a vacuum maintenance system. Each serves a very important part in the useful life of the container.

  • Page 25: Liquid Content Gauge

    Any test results greater than two times the listed value is indicative of a failed or failing vacuum. If NER is found to be high, contact Taylor-Wharton or your distributor. An increased evaporation rate is shown by fast pressure building, but it is not dangerous, because the container is protected by a pressure relief valve and an inner container bursting disc.
