Smaller 3000L Media Prep vessels were affected in the same manner for whereas the CIP flow rate specified was 60 Gpm, only 40 Gpm was possible, with an excessive puddle in the vessel.
A quick effort to obtain dimensional data for the X-Type Vortex Breakers followed, and the tank vendor was able to supply fully detailed drawings for each of the 65 vessels.
