Lorillard CompanyThe funnel of a cyclone is an example of the shape aswirling gas assumes.

2 This is commonly called avortex flow. Large circles of gas revolve downwardinto graduated smaller circles, with an ever increasingcentrifugal force. Penn s cone-shaped baffle matchesthe funnel-shaped configuration of the vortex flow andthe entire perforated basket helps eliminate moisture from theflow path along its entire length. This cone also has theadvantage of providing a dead-air space outside the center flowarea, where separated water particles drop harmlessly downthrough the perforated plate to the drain so that moisture can-not be picked up again by the flowing gas.

3 Because the PennCyclonic separator is also designed for natural vortex flow,pressure drop is minimized, while an extremely high separatorefficiency is Baffle Perforated plate allows for free flow ofentrainment to drain area.

The Califor-nia concern which coats these can-dies with sugar uses steam in partof the process. The steam oftencaused the sugar to lump untilPenn inline separators solvedthe lump problem by removing theexcessmoisture. Penn got thingsgoing smooth again!Penn ProtectsStainless Steel KettlesA leading manufacturer of canned fruits and vege-tables in Kentucky had a problem with its stainlesssteel cooking kettles.

5 The steam supply to thekettles contained too much moisture. This excessmoisture combined with the pressure, was respon-sible for pitting the steel in the kettles. The com-pany purchased a Penn separator , which solvedthe problem. Since them, the company has pur-chased several more, knowing the separators willmore than pay for themselves by extending the lifeof the stainless steel ll find our factory trained representatives most helpful in helping yousolve your particular problems. Don t hesitate to call upon their InlineGases and entrainment enter the separator and are quietly directed into a circular path byPenn s Helical Baffle, PHBTM.

6 Quiet is an important word because medium velocity gasesflowing through vanes or slots can produce noise. Efficiency is also important. PHBTM develops maximum centrifugal force with minimum pressure drop, insuring good, strong,cyclonic spinning the entire length of the separator . Entrainment flows to the drain and flowingsteam or gases escape clean, dry and free of entrainment through the central vortex outletback into the flow line. Re-entrainment is restricted because the drainbaffle develops aboundary layer which separates flow area from entrainment area.

Sheet IH418 R4 INSTALLATION AND Piping IS MADE EASY WITH PENN SEPARATORSI nstallation and Piping are simplified byPenn Separators because all separatorsare inline type. It is only necessary to allowfor the inlet to outlet distance given for thespecific type separator chosen. It is recom-mended that inlet and outlet supports beused on smaller units, and that on largerunits (6 and above) the inlet and outletsupports be used in addition to a centralpipe hanger trapping in separators is most impor-tant so that separated entrainment can bereadily drained from steam, air and othergases.

8 The Penn installation sheet (INST-492) discusses this in greater detail. Thetrap selection charge (108A94, pC7-D7)simplifies selection for specific flow andother conditions. Penn s sales people arealways pleased to assist you. Don t hesitateto give them a s Upflow separator is specifically de-signed for pipe-risers . Note that specialtreatment is given to the insertion of Penn sHelical Baffle, PHBTMso that an area existsoutside the main flow area where entrainmentcan flow to the drain area without being pickedup by the main flow system.
