The new degassing units from TARTLER free the media handling from
On the basis of vacuum technology, the plant manufacturer TARTLER now offers several system solutions for degassing high and low-viscosity materials. Primarily developed for filling or conveying processes in plastics technology, they are sometimes also suitable for other applications where the air-free processing of pasty or low-viscosity fluids is of central importance. Shortly before the turn of the year, the company presented its innovative degassing units to a select circle of experts.
“If we have to, we’ll put everything under vacuum now” – with these words Udo Tartler welcomed a small group of experts from the plastics and fluid technology sector a few weeks ago and took them to the area of his assembly hall where the finished machines and systems are prepared for final acceptance. Here, the company boss had all four system solutions that had been developed in his company for the degassing of high and low-viscosity materials set up: The filling unit TAVA F, the drum change unit TAVA D, and the degassing unit T-EVAC in its offline and inline versions. They all operate with vacuum technology and serve the purpose of freeing the process engineering handling of pasty and low-viscosity media from disturbing air and moisture – both when filling in lidded drums and when feeding into dosing, mixing or other processing systems. Depending on the series, TARTLER now supplies these degassing systems not only to manufacturers and users of synthetic resins, but increasingly also to those in fluid, chemical and process engineering. And that is because here, too, the air-free processing of high and low-viscosity media plays an important role in many areas and can be optimised by using TARTLER’s vacuum-supported systems.
Filling lidded drums without air
With TARTLER’s semi-automatic vacuum station TAVA 200 F, material manufacturers can fill pasty and low-viscosity media air-free into 200-litre lidded drums. The system can also be designed for other container sizes.
With the systems in the TAVA F series, TARTLER offers a system solution that can be used across all industries and with which high-viscosity and pasty semi-finished products can be filled into standard clamping ring lidded drums in a reliable process. This makes them interesting not only for use in plastics technology, but also for manufacturers of adhesives as well as sealing, filling and design compounds. In all these areas, the materials are usually delivered in complete containers to users of conveying, dosing, mixing and application systems and are mounted directly into them. Unwelcome air inclusions in the material, which can arise when the manufacturer fills the drum, prove to be extremely problematic.
“If this harmful air reaches the dosing pump during extraction, delivery and dosing, the processing process is massively disturbed. It is not unusual for the process to have to be stopped and the entire system to be flushed out with material until all air has escaped and it can work properly again,” explains company boss Udo Tartler. In such cases, it is not just a significant loss of material that has a negative impact; often, additional costs are incurred as many parts are difficult to clean or even have to be disposed of as scrap.
