The solEX NG 105 model, which completes the series of the most powerful single-screw extruders from battenfeld-cincinnati and provides a further optimally matched size level, celebrated its premiere at this year's K show. The series comprised the 45, 60, 75, 90 and 120 models. The solEX 105 fills the performance gap between the two large extruders perfectly. Naturally, the 105 machine with a length of 40 D, which covers a performance range from 1,680 to 2,100 kg/h, offers all the familiar features of the previous models and also includes valuable new innovations.

The machine is also equipped with a newly developed water supply. The solEX NG 105 has its own internal water supply, which is filled once with water including corrosion protection. Previously, the extruder was usually supplied with water for cooling the processing unit, gearbox and motor via the service water pipe in the processing plant. This can have two main disadvantages: Firstly, the impurities contained in the water, e.g. sand, can cause cooling channels to become clogged. Secondly, the cooling water reaches the components at a constant, usually low temperature. While cold water is advantageous for cooling the processing unit, it increases the lifespan of the engine and gearbox if the cooling water is at a low temperature. These requirements are met by the own water supply, which is mounted on the extruder.
“The extruder's own water circuit is so convincing that we will be providing it for all our models in future,” promises Heinrich Dohmann, Director Mechanical Engineering.
All solEX extruders of the New Generation (NG) have a processing unit consisting of an internally grooved barrel in combination with a matching screw and grooved bush geometry, resulting in technical process advantages:
a reduced axial pressure profile reduces machine wear. In addition, high specific output rates at low screw speeds ensure high efficiency and gentle, but very effective and homogeneous melting performance reduce the melt temperatures by around 10°C. This enhances the quality of the end product and results in energy savings. Compared to the predecessor model in the solEX series, the NG models achieve around 25% higher output when processing HDPE and even up to 40% higher output with PP.
