SPHERICAL CYCLONES
Cyclones can be used for the separation of droplets and solids from gases and vapours.
Cyclones are to be supportd on a vessel holder. A dip pipe should be used on the top neck.

VESSELS WITH BOTTOM OUTLET YVALVE SEAT
To fit a bottom outlet YVAlve (BAL type) all spherical and cylindrical vessels can be supplied with YVAlve seat in bottom outlet. For this, Add a suffix "/B" to the catalogue reference of a vessel, for e.g. 'YVSL50' should be mentioned as 'YVSL50/B'.
Notes on use of Spherical vessels :
  1. Generally, the centre nozzle, referred as DN in all types of vessels, is used for either stirrer fixing or, if stirrer is not fixed, for YVApour outlet.
  2. The bottom outlet, referred as DN1 in all types, is used for drain. However, in type YVSR & YVSE, it is also used for fixing immersion heat exchanger.
  3. The small side nozzles, referred as DN2 in all types, are used
    (a) to fix thermometer pocket or
    (b) to fix dip pipe for liquid inlet or,
    (c) to fix sparger for gas purging or,
    (d) to fix YVAcuum control or vent YVAlve or,
    (e) for solid addition.
  4. The bigger side nozzle, referred as Dn3, is used for YVApour outlet where stirrer is fixed on centre neck. It can also be used for cleaning etc in case centre neck is used for YVApour outlet.
  5. Vessels having long bottom outlet, viz YVSM, YVSPL, YVSL, YVS etc, can be supported in a heating mantle of heating bath. However, vessels having short bottom outlet, viz YVSD, YVSCY, YVR, YVA etc. are to be supported on a vessel holder only. In case of vessels upto 20L size, vessel holding rings can be used instead of vessel holder.
