Tartler: bubble-free drum filling and vacuum drum changing
The fully automatic vacuum deaeration system with vacuum clamping drum from Tartler scores highly when processing highly viscous silicones, polyurethane or epoxy resins in highly automated dosing and mixing systems.

Anyone who processes highly viscous silicones, polyurethane or epoxy resins in highly automated dosing and mixing systems currently has three basic options when it comes to routinely replacing the clamping ring lid drums with the A and B components: manual drum deaeration using a ball valve, which is not recommended, the currently widespread method in which deaeration takes place under vacuum, or the new fully automatic vacuum deaeration system with vacuum clamping drum from Tartler.
Pioneering for paste-like resins
The plant manufacturer's new TAVA 200 D system solution is able to fulfil all process and safety-related requirements. Problems when routinely changing material containers with highly viscous polyurethane or epoxy resins. This is a Fully automated dosing system with vacuum drum for picking up, pumping out and venting standard industrial lidded drums.
The TAVA vacuum drum works like a vacuum chamber. This makes it possible to generate a very high vacuum (-0.97 bar) in the drum, which prevents the drum from imploding. (Image: Tartler GmbH)
The solution guarantees that No air intake during drum change into the mixing and dosing system because a vacuum of minus 0.97 bar is generated between the material surface and the follower plate. The air present in the drum is channelled via Vacuum connection completely and continuously through an air-permeable but not media-permeable drum follower plate.
Any air that may have entered the feed and dosing pump is also detected, as pasty material may have dripped out when the previous drum follower plate was lifted. A Overpressurised spraying is generally excluded, as with the TAVA 200 D, the follower plate is moved out under pressure and subjected to a low vacuum shortly before it exits the drum.

The TAVA 200 D from Tartler generates and regulates the vacuum via a Process-orientated control system. The vacuum is only switched off when there is no more air in the system.
A safe bet: The NODOPOX 2K dispensing system is equipped with two vacuum clamping drums. TAVA 200 D prevents air from entering the system and the process during the drum change. (Image: Tartler GmbH)
Maximum process optimisation and safety
The system is user-friendly, works Fully automatic and offers the user Full control with zero material loss, zero risk of spikes and zero manual labour. In combination with the intelligent machine control mixing and dosing systems and the NODOPOX and TARDOSIL series from Tartler, the TAVA 200 D sets a new standard in the processing of paste-like polyurethane and epoxy resins as well as silicones.
As Areas of application of the system The fluid, filling, packaging, mixing, dosing and plastics technology sectors are potential applications. It also scores highly in adhesive production, the manufacture of sealants/fillers and for bottlers of plastics, industrial greases and oils.
[infotext] The systems are currently finding their way into wind adhesive processing and are in the test phase in many other application areas where material processors are struggling with air inclusions in their pasty or highly viscous material and where product quality suffers. [/infotext]
Innovative plant engineering
For over 35 years, the name Tartler has stood for innovative plant engineering in the field of dosing and mixing technology for synthetic resins such as silicone, polyurethane and epoxy resin. Wherever single and multi-component synthetic resins are processed, the Low pressure systems of the company in use. The intelligent Modular construction of the systems, the high Development expertise and close cooperation with the material manufacturers ensure that every customer receives the technologically optimally customised System solution can be provided.
