Solution is to install a per
manently mounted flat plate Vortex Breaker in accordance with the previous slide, 2X to 3X the diameter of the outlet, and 1/2″ to 1
above the bottom of the vessel. Some s 2500L L vessel in a 2
pment facility where sixteen Media and Buffer
prep tanks and ten bioreactors were fitted with the sizeable and robustly mounted slightly “domed”
plate perhaps 8 times the diameter of the 2″ outlet. No puddle could be found
sadhsagjal when sprayed at 60 Gpm. 100 L Bioreactors with 1″ outlets could be sprayed at 45 Gpm with more appropriately sized vortex breakers.
Why is it necessary to spray a 10
0L Bioreactor at 45 Gpm? The an
swer is easy if it is connected to the sa
me 2″ CIPS/R distribution piping as the
tors. A minimum CIP flow rate of 45 Gpm is needed to meet the 5 Fps velocity requirement for all 2″ piping in the circuit, a point often overlooked by those who consider only tank diameter when specifying sprays.
