DIST D-2892/5236 CC

DIST D-2892/5236 CCComputer Controlled-Combined Distillation System according toASTM D-2892 (TBP)ASTM D-5236 (Potstill)The i-Fischer® Dist D-2892 / 5236 CC is afully computer controlled unit of turn-keydesign, and ready for use after installationand commissioning. The system is fully housedand equipped with doors in the frontand rear to satisfy safety requirements andto facilitate service aspects.The automatic fraction collector (in the systemsection TBP: with 20 receivers) includesa built-in internal balance for the determinationof the fraction weight, while theseparate volume follower system is used fordischarging the fractions into the final receiversand the determination of the fractionvolume as well as for the direct distillationrate control.The automatic fraction collector (in thesystem section Potstill: with 12 receivers)includes a built-in internal balance and volumefollower system, which is used for thesimultaneous determination of the fractionweight, volume and for the direct distillationrate control.The vacuum equipment and the controlsystem are used for alternative operationof both distillation processes.4
