Date Hour ID Note
Fri 25/Nov/05 --:-- FS According to the User Manual, the amount of C4F10 required is:
m=(25/2 + V + 5)* 1.5 kg
where V= volume of the pipes from cooling plant to the sectors, in litres.
In our case V=(Pi*D^2)/4 * l * 10 with D= 4 mm, l= 24 + 5.5 + 5.5 + 5.5 = 40.5 m, V~ 5 l -> m= 33.8 kg.
Transfer stopped at about 33 kg, with almost the same value read from PLC (force sensor) and mass difference with the balance.
We used the Wigam Easy Rec 45 for this purpose with the scheme reported on the paper logbook. I took about 4 h! Better se traditional methods. Initially the bottle was 82.4 kg.
