CONICAL VACUUM DRYERS & SSP
REACTORS MODEL 159
Conical rotating vacuum dryer systems
Conical vacuum dryers deliver gentle, uniform drying at low temperatures and eliminate the contaminating and destructive effects of air drying. These drying systems are ideal for powders, crystalline or heat sensitive materials that need to be dried without excessive agitation.
PET solid-state reactor systems
BOC Edwards is the preferred equipment supplier of the plastics industry for solid state polymerization (SSP). SSP systems are sold as complete packaged systems to improve product uniformity and dramatically shorten cycle times in processing of PET, PEN, nylon and other polymers. As batch systems, they offer significant advantages over continuous solid-stating techniques. These include easier switches from one product to another, and easier specification changes for processing a single polymer, in order to achieve the various molecular weights (intrinsic viscosity) required for different end users. The unique Plus Surface design is an extended heating surface concept which significantly improves heating surface/volume ratio. |
Plus-Surface results in 115% more “wetted” heat transfer area while sacrificing only 6% of working volume. Plus-Surface is a distinct advantage to polymer processors since it dramatically reduces cycle times andenhances mixing characteristics to ensure product uniformity.
