Examination

Seat tightness and set pressure of the safety valve may

only be examined by means of t he bubble methodoutlined below. Contamination and corrosion of the valvemechanics are thus avoided. The set pressure is ind icatedon the type plate of the safety valve.

1. Admission of Test PressureFor the admission of the test pressure, a suitable testingdevice has to be used. With safety valves which shall not bedismantled, the feeding pipe from the pressure room of thevessel has to be locked.Do not carry out examinations wi th oxygen or combus-tible as well as cor rosive gases.

2. Examination of Seat Tight ness Increase the test pressure to 90 % of the set pressure. Thevalve has to remain tight, i. e. that no bubbles may produce.

3. Examination of Set PressureSlowly increase the test pressure to 100 %. The set pressurewill be indicated by a clearly increased number of bubbles.

Full-flow safety valves do open abruptly ! Possibly,set pressure and opening pressure are identical.

4. Examination of Opening PressureRemove rubber bungs and slowly increase the test pressure.The opening pressure may exceed the set pressure by up to 5%. The full flow can mostly be realized as stress-relievingbang.

For the pre-assembly of the progressive ring, the hardened

pre-assembly muff is recommended as follows: Type VOMO12 L for MG 84, manufacture: Ermeto.

Media 04 PN 40 with 2 relays4 Valve "instrument leads below"

Determination of the Vessel Level• by reading the scale of the level indicator in litres un-

der consideration of the gas type.

Note !• Valve 4 opened.

Caution! The positive pressure relief and seal-offdevice protects the vacuum room from overpres-sure. Re-evacuation may only be carried out by• manufacturer’s skilled staff

The protective cover (2) intercepts the valve insert(1), when there is overpressure existing in the vacu-um room.

• Do not remove the protective cover (2).• Protect the valve from heat as well as cooling, as

brittleness results in the loss of the operating vacuum.

Cryotherm GmbH & Co. KG recommend that the userrequest an EU – Safety data sheet fo r liquid n itrogen at his

gas supplier

Caution, when handling intensely cooled liquid gas-es!Observe the following documents and procedures:• Safety advices „Handling with cryogenic liquefied

gases ”• Regulation for the Prevention of Accidents „gases“

BGV B 6 (VBG61)

• Regulation of pressure devices

For safe operation:• Additional aggregates for filling/withdrawal have to be

adjusted to the operating conditions of the vessel.• Test the tightness and function of the fittings at regu-

lar intervals.• Use original spare parts.• Employ suitable tools.•

Keep fittings free from oil and fat due to danger ofexplosion with oxygen.• Do not operate valves abruptly or jerkily.• Protect lockable rooms against exceeding of the max-

imum operating overpressure by means of a safetyvalve.

• Have adjustment, maintenance and repair workdone only by authorized skilled personnel.

• Do not carry out any mechanical and thermal work atthe vessel (loss of vacuum).

• Do not transfuse contents with foreign gas.• Do not overcharge the vessel.• Protect safety valves against splash water and lees. • Wear gloves and safety glasses.• Loosen the screwings only in unpressurized condi-

tion.

Transportation and Assembly

13

Transport of the vessel

• Observe safety instructions• Avoid impacts and strong shocks

Transportation in evacuated and warmed up condi-tion only !

• Close Valves 1(filling valve), 10 (pressure raising), 30(overflow) 41.1/41.2 (purge valve)

• Maximum value at Manometer 5 (pressure inside thevessel) 0,1 bar, otherwise relieve pressure: openValve 30 (overflow) until the pressure 0,1 bar at ma-nometer 5 (pressure inside the vessel) is achieved.

• Mount sealing cap on filling and withdrawal coupling

Observe national and international regulations in the

case of transport on the road.(Only without filling!)

For transportation use the fork lift attachments (longitu-dinal and across) and the crane eyes respectively.

Installation!Installation only on planar and hard access subgrade in

interior- or outside area.Observe PED (pressure equipment directive)

- Consider installation space- Take care of good ventilation indoors- In outside area shut off the control box against

unauthorised access (padlock)- Place exhaust – gas line (at least DN 25) out – of

doors

At tention: d ischarge of cryogenic liquid !

The vessel can be commissioned immediately after delivery.

Observe safety inst ructions, chapter 3

Note !• When cooling down the hot vessel to operating tem-

perature, increased boil-offs do occur.• Take care of good ventilation indoors• Place exhaust-gas line out of doors

Observe !• Observe safety instructions chapter 3• Cylinder filling only via certificated and approved fill-

ing system• Wear gloves and safety glasses• Protect the vessel against damage• The operating pressure of the filling system must not

be higher than 3 bar (ideal 2 bar) otherwise the safetyshut off valve will act ( see appendix safety shut-offvalve)

Filling:• Attach transfer hose between the SIRIUS ® - Vessel and the

withdrawal Vessel.• Open Valve 1 (filling valve) an Valve 30 (over flow).• Open withdrawal valve at the filling system• Stop filling when:

• Pointer of the level indicator is 5% below maximum.• Pressure of the pressure gauge (5) rises• liquid pours out of Valve 30 (overflow)

•

Close Valves 1 (filling valve) and 30 (overflow)..

• Close the withdrawal valve on the filling system, reliefpressure from the filling line via valve 41 and loosen thefilling line

Note !• Open Valve 30 (overflow) for pressure relief in the

SIRIUS ®.• Adjust the working pressure only as high as required

in order to avoid an undue heating of the medium.• Avoid blowing-off of the safety valves. Relieve pres-

sure, if required.

Withdrawal of liquid• Connect the withdrawal hose at the withdrawal coupling.• Open valve 11.• Close valve 11 after withdrawal of liquid.

Observe safety instructions !

Note !• Adjust working pressure only as high as required in

order to avoid an undue heating of the medium.• Avoid blowing-off of the safety valves. Relieve pres-

sure, if required.

Pressure build - up 1. Slowly open Valve 10 (pressure raising).2. Screw-in the regulating screw at 8 (pressure build-up

control valve), until the working pressure at Manometer5 (pressure inside the vessel) is achieved.

3. The Pressure Build-up Control Valve 24 is closedabove the blow-down pressure.

Hinweis !• Screw-in the regulating screw for pressure increase.• Unscrew regulating screw for pressure decrease.• Depending on the filling ratio, operating overpressure

and type of gas, the pressure build-up needs varyingtime until the desired working pressure is achieved.

• Adjust the working pressure only as high as requiredin order to avoid an undue heating of the medium.

• Avoid blowing-off of the safety valves/gas controlvalve. Relieve pressure, if required.

• The icing of the pressure build-up evaporator (Cu-

gilled pipe) is operational.

For pressure relief close Valve 10 (pressure build-up)and open Valve 30 (overflow) until the working pressureat Manometer 5 (pressure inside the vessel) is achievedThe overpressure of the vessel is limited upwards overthe adjustable Gas Control Valve 25.

• Adjust the desired maximum pressure at Gas ControlValve 25 (at least 0.5 bar above the set pressure ofthe pressure build-up control valve)

• Screw-in Regulating Screw 8 for pressure increase.• Unscrew Regulating Screw 8 for pressure decrease

• With conventional use, the vessel does not requireany special maintenance or attendance.

• Regular examinations with regard to operativenessand tightness of the fittings and screwings are rec-ommended.

• Every two years, the safety valves have to examinedwith regard to function and set pressure. The ma-nometer indicates the set pressure.

• Carry out vacuum work only at the manufacturer’sworks.

• Observe the instructions for handling, examinationand assembly of the safety valves.

• Only use original spare parts, according to Item 2.9(accessories / spare parts).

• Have repair and maintenance work carried out only byskilled personnel.

• Carry out recurrent examinations at the manufactur-er’s works.

Faults

21

Immediately put the SIRIUS ® Storage Vessel out ofoperation, in case that• the fittings are leaky.• the safety valves blow off intensively.• the rate of evaporation is too high.• the outer vessel is thawed / iced-up, which indicates a

loss of vacuum.

In case of gas escaping,• there exists the danger of suffocation• open windows and doors• leave closed rooms

Vessels with vacuum loss are useless and have tobe returned to the manufacturer for examination /repair.

In case of queries, please indic ate• type of vessel• maker’s number• year of construction
