Save Costs with Automatic Dosing Calibration

With the Rollepaal Gravimetric Systems (RGS) you can control the flow of material to ensure a stable extruder output regardless of fluctuations in bulk density. The automated calibration within our solution reduces overweight and ensures accurate dosing. RGS is engineered to enable a mass flow which makes your operations as efficient as possible, minimizing waste and keeping costs low.

Multi-Component Dosing: Up to Six Additives Simultaneously

Rollepaal Direct Mixing (RDM) is engineered to ensure accurate dosing of each component and to improve multi-component dosing efficiency. RDM is capable of dosing up to six additives at the same time, PVC resin and the necessary additives can be mixed directly on top of the extruder, meaning no need for a mixing plant. 


Easy to Operate and Clean

Our solution is engineered for ease of operation and maintenance, reducing downtime and optimizing productivity. Cleaning and operating our Feeders & Gravimetrics is quick and easy, ensuring maximum uptime to meet customer needs. The user-friendly interface, moreover,  ensures quick and intuitive operation, reducing the time needed for operator's training.

Connected with integrated software

Furthermore, our Feeders & Gravimetrics are connected with a centralized and integrated software system, simplifying operational management. Operators have seamless control of the system, thereby optimizing productivity while keeping costs low and plant managers satisfied.

Color Additive Stability: Results Guaranteed

Our Feeders & Gravimetrics are designed for maximum stability in color additives. We understand the importance of consistency in polymer processing, and our solution delivers reliable and consistent results, satisfying pipe producers needs with confidence.
