Right: The Econia 3000 is a fully automated underwater pelletising system


designed by Econ for highly efficient and sustainable production


The company says it will continue to uphold its development philosophy of creating value for customers and continuously empowering the industry, accelerate the R&D and industrialisation of domestic high-end equipment, and contribute to achieving independent control of more key technologies in Chinese manufacturing. The CPS-F is a scalable pelletising


platform, developed by Buss for de- manding compounding processes. The new CPS-F 200 unit, the first size in the flange- based design that can be directly connect- ed to the company’s Compeo kneader series, was presented at K2025 with additional sizes following from early 2026. The CPS-F is particularly suitable for cable and performance compounds, as well as viscous or porous polymers. Well-designed mechanical interfaces mean the unit can be combined not only with Buss systems but also integrated as an OEM-independent solution into existing compounding lines. The adaptable flange, adjustable discharge height, and easily accessible utility connections for water and electrical supply, enable flexible integration even with limited installation space.

Cutting consistency The heart of the CPS-F is an exchangeable, segmented die plate with special geometry that compensates for thermal deformation. This keeps cutting quality consistent even under high pressure and temperature, a key aspect for consistent pellet quality. A rear-mounted drive allows access to the cutting zone without having to open the drive train, which saves time during cleaning and mainte- nance. A manual rotor brake with release mecha- nism and viewing windows with optional lighting further enhance operational safety, while additional features include an optional screen changer for inline filtration, integrated pressure moni- toring for process control, short material flow paths for clean processing, and compact, accessible design with clearly defined interfaces. With a throughput range of 80 to 3,500 kg/h, the CPS-F series, comprising four sizes, spans a broad application spectrum, from flexible lines to high-perfor- mance production. Compared to conventional

underwater pelletising systems, Buss said the CPS-F offers advantages including up to 50% lower pressure drop meaning more energy-efficient

operation and a 20-25% lower total cost of owner- ship. It is suitable for dual-mode users as the unit is switchable between wet and dry operation so it can be used in various application product families. Particularly helpful for manufacturers working with changing formulations or materials sensitive to temperature variations, the CPS-F represents a precise, reliable, and economical solution whether for cable compounds, performance compounds, or specialty applications, according to the company.


Glass fibre At K2025, Austrian company Econ presented its own underwater pelletising system, EUP50, in combination with the Econ Dehydrator, to show- case the granulation of glass fibre-reinforced polymers under real production conditions. The material composition used (PP with 30% glass fibre content) imposes demanding requirements on process stability, cutting precision, and drying efficiency. The company said it chose this arrange- ment to demonstrate how precise control of process parameters, consistent pellet formation, and reliable residual moisture removal, can ensure uniform product quality even under challenging processing conditions. Econ product specialists were on hand to explain the features and functional principles of the system, including the hydrody- namic design of the cutting head, process water temperature control, and the energy-efficient operation of the dehydrator, helping K visitors gain insights into the system’s operation and its suitabil- ity for demanding pelletising applications. In addition, Econ presented other highlights


from its current product portfolio, including the Econia 3000, a fully automated underwater pelletising system designed for highly efficient and sustainable production which offers intelligent process control for optimal resource utilisation. Meanwhile, the EPO-N 1000 system provides exceptional flexibility and productivity through its modular construction and adaptable process
