CONTAINER SAFETY NOTE: For detailed information on the handling of cryogenic liquids, refer to the Compressed Gas Association publication: P-12 “Safe Handling of Cryogenic Liquids” available from the Compressed Gas Association, Inc., 1235 Jefferson Davis Highway, Arlington, VA 22202. Pressure Hazard - The containers covered by this literature may contain pressures up to 230 psig (16 bar/1586 kPa.

Handling the Container The XL Series containers are very rugged liquid cylinders. All cryogenic liquid cylinders have an inner container and an outer container with an insulated vacuum space between them. Any abuse (dents, dropping, tip-over, etc.) can affect the integrity of the containers insulation system. When fully loaded, the XL-55 in argon service will contain 551 lb. (250 kg) of product. While moving a full container, you may be handling 821 lb. (372 kg) and you should treat the load accordingly.
OPERATION XL-45/50/55 Component Locations The XL-45 will store up to 169 liters of product, the XL-50 up to 181 liters and 200 liters for the XL-55. All three cylinders can deliver either liquid or gas. The following component and circuit descriptions are pertinent to the operation of all the containers and should be read before attempting operation. The components may be identified on the Component Location Illustration.
inner container is vaporized in a heat exchanger which is inside the outer casing. The expanding gas is fed into the upper section of the container to build pressure. The resulting pressure will drive either the liquid or gas delivery system. Pressure Building is not normally required unless container pressure drops below the gas output pressure desired. If, for example, the container pressure gauge reads 75 psig (5 bar/517 kPa), and your gas pressure requirement is 100 psig (6.
The VENT Valve – This valve controls a line into the head space of the container. It is used during the fill process. The VENT valve acts as a fill point during a pump transfer, or to vent the head space area while liquid is filling the inner container during a pressure transfer fill through the LIQUID valve. The Pressure Gauge – The pressure gauge displays the internal container pressure in pounds-per-square-inch or in kilo Pascals.
Increasing Gas Supply Capacity – Two or more liquid containers may be manifolded together. Accessory manifolds are available for use in creating a higher capacity gas supply system. The XL-45/50/55 can supply gas at flow rates 1 up to 350 cfh @ NTP (9.2 cu.m/h @ STP) using only its internal vaporizer. At low flow rates, the gas supplied will be at near ambient temperature. As the flow demand is increased, the gas will become proportionately colder.
Determine Proper Fill Weight 1. Visually inspect the container. Do not attempt to fill containers with broken or missing components. NOTE: The weight calculation includes the weight of residual liquid and is applicable to both Pressure Transfer and Pump Transfer filling methods. 2. Move the container to a filling station scale and weight it both with and without the fill hose attached to determine the weight of the fill line assembly. The difference is the fill line weight. 3.
2. During the fill, monitor the container pressure and maintain a pressure of 10-15 psig (0.7-1 bar/69-103 kPa) by throtting the VENT valve. 3. When the full weight is reached, close both the LIQUID and VENT valves. 4. Close the liquid supply valve and open the dump valve on the fill line assembly. 5. Disconnect the fill line from the container and remove the container from the scale.
Fill Hose Kits Fill kits are available with different combinations of hose length and fittings for a specific gas service. The following chart identifies the available transfer hoses and fill tee assemblies.

Service CGA Connection Part Number Inert (N2, Ar) CGA 295 GL50-8C60 Read the Safety Precautions in the front of this manual before attempting any repairs on these containers. Also follow these additional safety guidelines while performing container maintenance. MAINTENANCE PROCEDURES Never work on a pressurized container. Open the vent valve as a standard practice during maintenance to guard against pressure build-up from residual liquid. Use only repair parts cleaned for oxygen service.
CAUTION: When changing gas service, install the proper fittings – DO NOT use adapters. The following procedures address the physical changes to the container only. For detailed procedures on the decontamination of the container itself, refer to CGA pamphlet C-10 “Changes of Service for Cylinders Including Procedures for Inspection and Contaminant Removal.” GAS SERVICE CHANGE KITS Kit Part No.
Regulator Removal or Replacement Procedure 1. Close manual Pressure Building Valve. 2. Vent the container to atmospheric pressure. 3. Loosen and remove both the tube connections on the pressure building and economizer output sides of the regulator. 4. Remove the regulator from the container by unscrewing the valve body and elbow from the output of the Pressure Building Valve. 5. Repair the regulator and readjust its setpoint using the bench test setup. 6.
CHECKING CONTAINER PERFORMANCE Cryogenic containers are two container, one within 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. The high technology insulation is very effective in preventing radiated heat from entering the inner container.
WARNING: Cold surfaces should never be handled with bare skin. Use gloves and other protective clothing when performing this procedure. Wharton Customer Service at (334)443-8680 for disposition. FULL VIEW CONTENTS GAUGE MAINTENANCE The content of these containers is measured with the Full View Contents Gauge. The device consists of the gauge assembly beneath a clear plastic protective cover.
NOTE: The yellow band will move approximately ¼ in. (6.4 mm) to each 10 turns of the rod. NOTE: Make sure that the Gauge Assembly is not bent or out of line before reinserting that gauge into the container. Calibration For XL-45, XL-50, XL-55 Contents Gauge Installation Before installing a new or repaired gauge, inspect the gasket seals. If any damage is apparent, replace the gasket. (See following page for illustration.) 1.
again. CAUTION: When installing the gauge assembly, care must be taken to ensure that the float rod is inserted through the “guide ring” located on the liquid withdrawal line inside the container. If the gauge does not engage this ring, the contents indication will be inaccurate, or the gauge may be damaged in use. Contents Gauge Insertion 6.
