Page 2: General Information
CONTAINER Pressure Hazard – The containers covered by this literature may contain pressures up to 350 psig (24 bar/2412 kPa). Sudden release of this pressure may cause personal injury SAFETY by issuing cold gas or liquid, or by expelling parts during servicing. Do not attempt any repairs on these containers until all pressure is released, and the contents have been allowed to vaporize to ensure no pressure buildup can occur.

Page 4 CAUTION: Handling the Container When using a hoist, always insert hooks The XL Series containers are very rugged liquid cylinders. All cryogenic liquid containers into both lifting lugs. have an inner container and an outer container with an insulated vacuum space between Failure to do so could them.
Page 5: Operation
The XL-65/65HP will store up to 240 liters of product. The two cylinders can deliver either OPERATION liquid or gas. The following component and circuit descriptions are pertinent to the opera- tion of all the containers and should be read before attempting operation. The components may be identified on the Component Location Illustration.
Page 6: Flow Diagram
Pressure Building is not normally required unless container pressure drops below the gas output pressure desired. If, for example, the container pressure gauge reads 250 psig (17.2 bar/1724 kPa), and your gas pressure requirement is 270 psig (19 bar/1860 kPa), and the pressure building valve may be opened to build container pressure to 300 psig (20.7 bar/2068 kPa).

Page 8 WITHDRAWING GAS FROM THE CONTAINER To withdraw gas from the XL-65/65HP connect a suitable pressure regulator to the USE connection, and the output of the regulator to your external equipment. Then open the USE and the PRESSURE BUILDING valves. When the container pressure reaches 125 psig (8.6 bar/862 kPa) for the XL-65, —or 300 psig (20.7 bar/2069 kPa) for the XL-65HP –...
Page 9: Filling The Container
FILLING THE CONTAINER Cryogenic liquid containers must always be filled by weight to ensure there is enough gas head space (usage) for liquid to expand as it warms. Using the procedure below, first determine the proper filled weight of each container. The weight derived is then used in either the Pump Transfer of Pressure Transfer filling procedures that follow.
Page 10 Pressure Transfer Filling Procedure (Low Pressure Source) – Once you have deter- mined the proper full weight for a container, connect a transfer hose to the LIQUID fitting from a low pressure source of liquid. 1. Open the supply valve. Then, on the XL-65/65HP, open the LIQUID and VENT valves to begin the fill.
Page 11 Fill Hose Kits In use, the CGA Tailpiece couples to the fill connection on the container being filled. The Relief Valve vents pressure over 350 psig (24 bar/2413 kPa) that builds up in the fill line due to trapped liquid. The Dump Valve is used to allow the operator to blow-don the receiving container during a pump fill, or to relieve residual pressure from expanding liquid trapped in the line before disconnecting the fill line.

VENT TEE CHART The vent tee connects to a transfer hose to complete a fill line kit. Each assembly in- cludes a 3/8 in. pipe connector to CGA fitting with a a 350 psig (24 bar/2413 kPa) relief valve, and a ball-type dump valve. WARNING: Never put any liquid Service...

Page 14 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 econo- mizer output sides on the regulator. 4. Remove the regulator from the container by unscrewing the valve body and elbow from the output of the Pressure Building Valve.
Page 15 CHECKING CONTAINER PERFORMANCE Cryogenic containers are two containers, 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.

Page 19 HAND VALVE REPAIR Hand valves are an integral par of the container and the valve bodies rarely need replace- ment. However, the handwheel and internal part of the valves are renewable. The illustra- tion below are exploded views of the valves replaceable parts used on Taylor-Wharton liquid containers.

Partially thread Seat Assembly (12) (seat disc first) into large end of Bushing (13) leaving tan of nipple assembly exposed about 1/8 in. beyond top of Bushing. 2. Insert Seat Assembly (seat disc first) with attached Bushing, into valve body until properly seated.
