SAFETY Chart has conducted a rigid test program for liquid cylinders, both internally and through an independent testing laboratory, to verify the safety of Chart equipment. Chart cylinders are safely designed with the following features: 3 Keep all organic materials and other flammable substances away from possible contact with oxygen; particularly oil, grease, kerosene, cloth, wood, paint, tar, coal dust, and dirt which may contain oil or grease.
4 SAFE HANDLING This section describes and illustrates proper cylinder handling procedures. Major considerations for liquid cylinder handling are summarized as follows: Caution Only use replacement equipment which is compatible with liquid oxygen and has been cleaned for oxygen use. Do not use regulators, fittings, hoses, etc., which have been previously used in compressed air service. Similarly, do not use oxygen equipment for compressed air.
SAFE HANDLING Preferred Handling Procedures 4 This method is used when frequent and short distance moves of a liquid cylinder are required. Before utilizing this method of transportation, make sure the area over which the liquid cylinder is to be moved is flat and smooth. Figure B illustrates the preferred cylinder handling procedures. It shows the proper way to approach a cylinder when using a pneumatic-tired hand truck.
4 SAFE HANDLING Use Straps Do Not Use Chains Use A Handtruck And A Power Liftgate Figure C Transporting Procedures The Dura-Cyl/Cryo-Cyl Series liquid cylinders are designed to withstand the normal handling associated with transportation by truck. Do Not use chains. Chain tie downs will scratch the finish and could crush or dent the vacuum jacket. Figures C also shows the proper method of unloading a cylinder from a truck.

THEORY OF OPERATION 7 General Liquid cylinder operation is done completely with the control valves located on the top of the tank. The valves are labeled and color coded for easy identification: Fill/Liquid Valve – blue; Gas Use Valve – green; Vent Valve – silver; Pressure Building Valve – green. The various liquid cylinders of the Dura-Cyl/Cryo-Cyl Series have the same general operating characteristics.
THEORY OF OPERATION Filling Procedures 7 The liquid cylinder should be visually inspected before every fill for possible damage, cleanliness and suitability for its intended gas service. If damage is detected (e.g. serious dents, loose fittings, etc.) remove it from service and repair the unit as soon as possible. The following recommendations should be used to optimize liquid cylinder filling: * Keep the transfer lines as short as possible.
7 THEORY OF OPERATION Economizer Closed Pump Transfer The pump transfer method lowers the product losses associated with filling. Liquid may be pumped into the cylinder so that venting is not necessary. The vent valve on the liquid cylinder has a spray header that will splash the incoming cold liquid onto the somewhat warmer gas in the tank. The cold liquid will actually collapse the vessel pressure while being sprayed into the warmer gas.
THEORY OF OPERATION Pressure Builder 7 fer line. Normal liquid withdrawal operations are performed at lower pressure (approximately 22 psig) to reduce flash-off losses and splashing. For this reason, the pressure building valve is customarily closed during liquid withdrawals. Transfer of liquid at higher pressures can lead to excessive splashing of the cryogenic liquid which could result in burns to the operator and/or nearby personnel.
8 OPERATION OF CRYO-CYL 120 / 180 / 230 LP General The Cryo-Cyl 120/180/230 LP cryogenic liquid cylinders have been designed to transport, store and dispense liquid oxygen, nitrogen or argon in their liquid states only. Liquid product is generally used at ambient or very low pressures. The Cryo-Cyl LP has a working pressure of 22 psig ( 1.5 BAR )to allow for transfer into vented cryogenic dewars or equipment. The pressure is maintained in the liquid cylinder through its normal heat leak of the cylinder.

15 TROUBLESHOOTING The troubleshooting section of this manual deals with the normal operating conditions and the problems that may occur with the Dura-Cyl/Cryo-Cyl Series liquid cylinders. The troubleshooting guide assumes that the tank is in its normal operating environment having a cooled down inner vessel and a reasonable vacuum. Before troubleshooting an operational problem, the liquid cylinder should be examined for vacuum. 7.
TROUBLESHOOTING Problem Liquid cylinder builds excessive pressure or builds pressure too fast. Problem Cause 15 Corrective Action Low usage. If daily gas usage is under 100 SCF (2.8 NM3), the cylinder will build pressure. In liquid service, the cylinder should be equipped with low pressure relief valve and regulator. Normal pressure rise should not be more than 50 psi (3.4 BAR)per day. Cylinder is over filled.
15 TROUBLESHOOTING Problem Frost occurs on head or knuckle. Problem Cause Corrective Action Residual frost remains from This is normal. Ice may remain for days after a fill or heavy use. last fill or recent product use. Check for gas escaping from under sight gauge. Refer to Section 16, page 62, for repair. Sight gauge is leaking. Frost occurs evenly over the cylinder surface. This is normal. The gas withdrawal rate is high. Both the P. B. and gas use vaporizers are frosted. Cylinder has lost vacuum.
SERVICE AND MAINTENANCE General 16 WARNING: Cylinders used in oxygen service must not be changed to CO2 service. This section contains the information regarding the liquid cylinder care and maintenance. It includes the particular maintenance procedures for changes to the operating pressure, service pressure and liquid service changes. When performing a procedure that is described in this section, refer to the previous sections on operation (Section 8 through 13) for a components item number and location.
16 SERVICE AND MAINTENANCE Fittings And Decals It is very important that the proper fittings for the specific gas product being transported are installed on the liquid cylinder. The Compressed Gas Association regulates the fitting design so that equipment compatibility is based on gas product. This keeps from having a nitrogen tank being attached to a hospitals oxygen supply. DO NOT use fitting adapters.
SERVICE AND MAINTENANCE The following relief valve parts list shows the various pressure settings that are offered. The relief valves that are marked for CO2 and N2O are specially designed for those gas products. Reliquefying Solid CO2 In the event the Dura-Cyl HP/Cryo-Cyl HP loses pressure and the contents become solidified, the following procedure should be used: 1. 2. 3. 4. 16 Rego Relief Valve Part No.
16 SERVICE AND MAINTENANCE For Dura-Cyl with LCCM Pressure Control Manifold in Gas Service (Refer to Figure AA) psig is normal). Use an oxygen compatible liquid thread sealant (or Teflon tape) to prevent leaking. 4. Pressure test all new joints using an oxygen compatible leak test solution. 1. Close all four manual valves on the Dura-Cyl . 2. Back out adjusting knob (Item A) on pressure control manifold. 3. Release pressure in the container by opening the vent valve.
SERVICE AND MAINTENANCE Bench Set Combo Regulator Level Gauge Pressure Source Regulator Valve P.B. IN The liquid level gauge in the Cryo-Cyl LP model is a float and spring that approximates the amount of product in the container. The design of this gauge makes it possible to use the same float and spring for nitrogen, oxygen and argon. However, the liquid level decal must be changed for each product. The decals are marked N for nitrogen, O for oxygen, and A for argon. Relief Valve P.B.

18 SAFETY BULLETIN General Oxygen Deficient Atmospheres Cryogenic containers, stationary or portable, are from time to time subjected to assorted environmental conditions of an unforeseen nature. This safety bulletin is intended to call attention to the fact that whenever a cryogenic container is involved in any incident whereby the container or its safety devices are damaged, good safety practices must be followed.
SAFETY BULLETIN 18 Oxygen Enriched Atmospheres Nitrogen And Argon An oxygen enriched atmosphere occurs whenever the normal oxygen content of the air is allowed to rise above 23%. While oxygen is nonflammable, ignition of combustible materials can occur more readily in an oxygen-rich atmosphere than in air; and combustion proceeds at a faster rate, although no more total heat is released. Nitrogen and argon (inert gases) are simple asphyxiants.
