Optimum use of liquid and pasty media

TARTLER GROUP’s vacuum degassing systems improves material yield and reduces waste.

With the degassing system TAVA F, the TARTLER GROUP is offering a ground-breaking solution, through its subsidiary SOMATA, for the optimal handling of liquid and pasty materials and at the same time reduce cost. The vacuum-based system enables both manufacturers and users of high and low-viscosity fluids considerable advantages in material utilisation when filling new drums or refilling between drums. The processing quality is increased, waste quantities and production costs are reduced.

Air pockets, entrapped air and moisture, as well as process waste and unused left overs – these are the enemies of all users of high and low-viscosity fluids who want nothing more than an optimal and cost effective process. SOMATA GmbH from the TARTLER GROUP is providing manufacturers and processors with a strong ally to achieve these goals: The degassing station TAVA F. This vacuum system makes it possible for both liquid and pasty material to be filled into open top drums removing any “harmful air” and then be transferred to the application process – for example a dosing and mixing system. Primarily developed for use with thermosetting polymer technology, the TAVA F from the TARTLER GROUP has now also proven to be a highly efficient solution for other types of materials in which the air-free application of viscous or low-viscosity fluids plays a major role. For example, in adhesive and sealing technology or in the production of filling and design compounds. “The potential savings from using reconditioned materials and ensuring more stable processes are significant” notes company CEO Udo Tartler. He cites as an example “a renowned wind turbine manufacturers who use the TAVA F vacuum station, saves several thousand kilograms of synthetic resin paste every year going to waste and has been able to significantly reduce their costs in rotor production. At the same time, they have improved the ecological footprint of their production”.

Company boss Udo Tartler: “The savings on material and costs achieved by using the TAVA F vacuum station from our subsidiary SOMATA can be significant”.

Air-free filled ex works

The TAVA F is primarily of interest to all manufacturers who fill high-viscosity or pasty media into the standard open top drums and supply them as ready-to-use components to the operators of, dosing, mixing and application systems. SOMATA’s degassing station enables you to prevent undesirable entrapped air from forming in the material even during the factory drum filling and can provide your customers with guaranteed air and void free containers. Udo Tartler explains: “Entrapped air in the material causes the greatest problems during dosing. If this harmful air gets into the pump of a metering and mixing system during the dosing application of the material, the process is massively disrupted. Often it requires the process to be interrupted, where the complete system must be flushed out with fresh material until all air has escaped and it works properly again”. In practice, this tends to mean a greater loss of material and additional costs are often incurred as prefabricated components or upstream processes must be cleaned or replaced at great expense. Additional irritation for the user is caused by the fact that they are normally unable to reuse opened drums with residual quantities or collected material waste, which must instead be rejected and disposed of. This also has a negative impact and undermines all efforts to achieve better material (costs) balances. However, the example of the renowned wind power plant manufacturer illustrates the TAVA F’s ability to be a convincing solution to this problem. Here, the vacuum station from the TARTLER GROUP is used directly in production to recondition material residues from rotor blade production.

Degassing station as a treatment plant

During the processing of synthetic resin in the dosing and mixing systems of the rotor blade production, varying amounts of unmixed material residues accumulate in different process stages. Udo Tartler reports: “Our on-site analysis had shown that up to 11 kg of material still remain in the inliner when the barrel is empty. In addition, the testing and quality control of the mixing ratios for each rotor blade also leaves several kilograms of flawless material behind. And finally, further residues from production surpluses, purging and other ancillary work accumulate”. However, normally the material collected from different sources cannot be reintroduced into the production process, as air pockets would once again form when it is filled into a open top drum – and that is precisely what must be avoided. The wind turbine blade manufacturer therefore uses a TAVA F during production to degas the collected material residues and to guarantee that they are reintroduced into the metering and mixing machine free of harmful air. The reconditioned material can be carried out by a 2K-NODOPOX unit from TARTLER or any similar machine. “This enables considerable cost savings to be made. In the case of rotor blade production, almost all unmixed materials can be reused,” stresses Udo Tartler. The return on investment can be achieved in less than 24 months – in addition significant savings can be made in the added cost for safe and compulsory treatment of hazardous waste.

Air-free in just a few minutes

SOMATA GmbH offers as standard the degassing station TAVA F for the air-free filling and refilling of 50 and 200 litre drums. It can also be designed for other drum sizes upon request. The system consists of a device for clamping and stabilising the drum, a special combination lid for vacuum generation and filling, a vacuum pump and a control system with a touch screen. All components are installed on a base with a drum centring plate and accessible from all sides. The TAVA F system can be loaded manually with a new empty drum or be fully automated. The vacuum application of the drum and the filling of material is fully automated. After a few minutes, a drum is filled without air and is ready for use in production. This process is illustrated in SOMATA’s YouTube channel.

By the way: In addition to the TAVA F, TARTLER GROUP now offers three system solutions for degassing high and low-viscosity materials, namely the drum changing system TAVA D, and the degassing system T-EVAC in either offline or inline configurations. They are all based on vacuum technology and designed to free the handling of pasty and low-viscosity media from harmful air and moisture – both during the filling process and when feeding into the processing plant. As shown by the example of the TAVA F, these systems can also be used for reconditioning material residues and reducing production-related waste.
