CHS vacuum system

​LESS HANDLING, LESS CLEANING WITH FLEXIBLE VACUUM MIXING -
DISPERSION SYSTEM
The ability to disperse and mix under vacuum is becoming commonplace as it is often essential for performance and quality purposes to prepare products under closed conditions and that do not contain entrained air bubbles.  A new Vacuum Dispersion and Mixing System which offers users’ outstanding flexibility, is now available from laboratory instrumentation specialists FULLBROOK SYSTEMS. The range of Dispermat CHS Vacuum Systems, manufactured by VMA-GETZMANN GmbH, is ideal for small batches and sample production where vacuum is required.  
Unlike other vacuum dispersers the DISPERMAT CHS vacuum system offers users exceptional versatility because it is designed to accept single wall pails, buckets, non-standard and most importantly even users own containers. This means that materials can be processed without the need for dedicated vacuum containers, significantly reducing the time associated with handling and cleaning.  Suitable containers can be secured in the vacuum system quickly and easily in just a few simple steps. Users place the container on the mobile system trolley then a top-mounted fixing ring is screwed into place which securely holds the container in place. The vacuum cylinder is then placed over the container whilst the assembled vacuum system is positioned underneath the powerful Dispermat AE pilot plant vacuum dissolver, ready for the dispersion process to begin.
The dissolver disc is height adjustable even with the cover in place which allows the blade to be positioned at the perfect height to ensure that addition of powders can be made to the batch under optimum conditions. This allows for the ideal dispersion conditions to be achieved which are typically indicated by a slow, rolling product flow (“doughnut effect”). The complete process and the product under vacuum are able to be observed by the operator through a large viewing glass in the vacuum cover. To enhance viewing a powerful LED lamp can be added if required as an option.
A vacuum can be pulled on the product at any stage, either during dispersion or at the end of the process. An optional wall scraper is available so that high-viscosity and thixotropic products can be dispersed easily. The high torque scraper system motor is mounted on the top of the vacuum cover and can be adjusted using the control panel.   
The solid scraper arm within the vacuum container effectively removes any product residue which is sticking on the container wall and folds it back into the dispersion process. For  temperature sensitive applications, an optional PT100 probe enables operators to control temperature as required.
At the end of the dispersion process the container is simply released and removed, the finished de-aerated and dispersed product is held in its own container, so no transfer to another container, which often adds air back in, or cleaning is required. The CHS system is then ready to accept the next batch.
The Dispermat CHS30 (pictured) accepts 30 litre containers but is also available for container volumes up to 60 litres and also for other specific container sizes if required. An explosion-proof ATEX certified version is also available.
Dispermat CHS vacuum dispersion and mixing systems are ideal for smaller batch applications across a wide range of industry sectors, such as; paints, varnishes, pigments, additives, printing inks, powder coatings, chemicals, plastics, or wherever efficient, flexible vacuum dispersion is required.  ENDS.
