Plastic Pall Rings Brochure

astraPAK®PLASTIC PALL RINGSPERFORMANCE CHARACTERISTICS:An advancement on the Raschig Ring, the Pall Ringhas similar cylindrical dimensions but has two rows of windows with webs within the cylinder, which significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop.We are able to offer these in a variety of plastic: Polypropylene, PVC, PVDF, HDPE and glass filled and high temperature resistant Polypropylene.As standard we offer our Pall Rings in a natural colourbut if you need a different colour we are more than happy to help.FEATURES:CAPACITY vs PRESSURE DROPSuited in low pressure drop, high capacity applicationsA range of sizes allow the tower to operate at optimum efficiency and throughputHigh degree of randomnessConsistent ratio of free and blocked passages, independent of of orientationLarge Surface area: volume ratio augments the rate of liquid film surface renewal to improve mass transferHOLD-UP and TWO-PHASE CONTACTPromotes highly efficient two-phase contact and distributionA relatively high liquid hold-up promotes high absorption efficiencies, especially where the reaction rates are slowUninterrupted and consistent passages for gas and liquid flowVERSATILITYOpen, cross linked design provides a highly efficient use of thering’s surface areaRobust to variations in liquid and vapour distributionHIGH MECHANICAL STRENGTHThe cross structure of diametrical spars make it mechanically robust and suitable for use in deep packed bedsP-Series 16P-Series 25P-Series 38P-Series 50P-Series 90P L A S T I CPALL RINGSINDEX OTHERSERVICESTOWERPACKINGSTHE PALL RINGCOMPANYTOWERINTERNALSMETALLIC PALL RINGSALTERNATIVE PACKINGSwww.pallrings.co.ukThe Pall Ring Company LimitedNew Road CrimpleshamKing’s Lynn Norfolk UKPE33 9AST: +44 (0)1366 389680F: +44 (0)1366 389681E: sales@pallrings.co.uk Registered Office:The Pall Ring Company LimitedCrimplesham NorfolkRegistered No.055360124Specific Weight/(kg/m3)PP11069524542PVDF198128998467PVC165107827056T H E R M O P L A S T I C P A L L R I N G S – D A T A T A B L EPackingSize/mm1625385090FreeSpace/%8891949596PackingFactor/(m-1)3151761078051SpecificSurfaceArea/(m2m3)32020912710059NumberPer UnitVolume/(no./m3)213,00049,36012,1205,9601,090P-Series1625385090PACKAGING & TRANSPORTTerms & ConditionsP-Series 16P-Series 25P-Series 38P-Series 50P-Series 90
