Special operation for bake out
• To have a guaranteed cooling during bake out a special procedure is in place:– Both systems in parallel
• If 1 fails we interlock the bake-out– Safe cooling down at half the flow from the 2nd system
• If both systems fail a bottle is emptied through the transfer line to have cooling for an extended time.
– Operation at a temperature set point of -20’C

Blow system summary
• A failure of both system cause automatically a blow system activation.– Safe against: cooling system failure by interlocks– Power loss, blow system is activated in fail safe
condition meaning valves will be opened• Parts have been ordered from SR1 foreseen
test ( never carried out)• Blow system activation can be tested over
junction box.
