R-PTS from
rubitec ag

In the pharmaceutical and chemical industry every detail counts: particularly when powdered substances are involved, the demands on safety, purity and process control rise. With highly potent active ingredients or toxic substances in particular, closed conveying is therefore essential – without dust, without risk. That is exactly what the R-PTS from rubitec ag was developed for. It is a modern pneumatic transfer system that conveys powder under vacuum – safely, under containment and therefore ideal for sensitive substances. What makes it special is that the filter can be changed under containment (push-push filter), and the filter surface is considerably larger than in conventional systems.

The abbreviation „R-PTS“ stands for Rubitec Powder Transfer System – a system for conveying bulk materials using vacuum. The required vacuum is generated by a vacuum pump. This can either be supplied directly by rubitec ag or connected to existing equipment, according to the customer’s wishes. Unlike gravimetric methods, the PTS system therefore draws on the power of vacuum: the powder is pulled through closed pipework without coming into contact with the ambient air or the operating personnel. This not only avoids emissions but also makes it possible to bridge greater distances. Control is either pneumatic or via a PLC (programmable logic controller), depending on the complexity of the process. Both variants can be connected without difficulty to an existing process control system (PCS), so that material flow can be controlled centrally and monitored as effectively as possible.

The R-PTS from rubitec ag is more than just a simple conveying device; it is an important part of modern containment strategies. Like all our products, our R-PTS can be adapted individually and integrated optimally into existing containment systems. The modern Rubitec Powder Transfer System offers a range of advantages:

• Closed powder conveying by vacuum: The powder is moved through closed lines without contact; the entire vacuum-based conveying process has low product loss and reliably protects against emissions.
• Efficient push-push filter technology: High-performance filters of class H13 or H14 ensure safe exhaust air cleaning – a filter change is possible without interrupting containment.

• Cleaning without opening the system: Thanks to the WIP/CIP function (wash/clean in place), the system can be cleaned completely, with no dismantling and no break in containment.
• Safe dosing: Even powder flow.
• ATEX: Suitable for hazardous (explosive) zones up to zone 1/21.
• Containment-ready: Tested and usable up to OEB level 5. (conveying with nitrogen)

As a modular pneumatic transfer system, the R-PTS can be linked precisely with further components, such as our bag emptying stations, drum stations or big bag stations.

PTS systems are used wherever powder has to be conveyed reliably and without loss under containment conditions, with no manual intervention and no open transfer points. In the pharmaceutical industry they are used, for example, to transfer highly potent active ingredients into reactors or dryers under control. In chemical production they are suitable for the safe handling of toxic or reactive substances.
