The new Pre-Cleaner CL-X: Higher productivity and lower energy consumption

Double the production rate, with lower energy consumption per kilogram of fiber material – that might sound like a contradiction, but the new Trützschler pre-cleaner CL-X makes it possible. It gently and reliably removes coarse contaminants like leaf debris, stalks or seeds from cotton with minimum loss of good fibers. The pre-cleaner CL-X provides more efficiency and lays the foundation for a high-quality end-product before the cotton is further processed in mixers and fine cleaners.

The new CL-X especially meets the urgent demand for lower energy consumption. Energy efficiency is not only important for environmental and regulatory reasons. Due to rising energy prices, it is becoming an increasingly decisive factor for the competitiveness of spinning mills.

"During the development process, our main focus was on optimizing the fiber air flows. This is the area where we achieved the breakthrough. By forcing the air flow over two rolls, we have found a solution that allows lower power consumption at the opening rolls,” says Robert Többen, Head of Mechanical Engineering at Trützschler. “The fact that this flow is in the form of a spiral is also reflected in the name CL-X: The ‘X’ comes from the Greek word for spiral, Helix.”

In comparison with the current benchmark, the CL-X saves up to 30 % energy (see chart 1). In addition to the optimized flow, an integrated air separator contributes to reducing the transport air by ensuring that only excess air has to be removed, rather than all of the air. Less exhaust air means less energy consumption.

The CL-X also provides significantly increased productivity. At a maximum of 1,600 kilograms per hour, the production rate from one CL-X corresponds to the rate achieved by two CL-P models. This gives customers the flexibility to operate at high or low productivity rates with one machine.

On top of this, the new CL-X is characterized by its excellent cleaning results. Trials conducted at a Turkish customer have shown that it reached a nearly three times better cleaning efficiency compared to the benchmark (US cotton, see chart 2). The improved grid geometry enables better separation and gentler tuft handling. Furthermore, a 2.60 m long cleaning section provides a maximum degree of opening and cleaning tufts.

The lot management system enables direct, automated coordination with the Bale Opener BO-P. The speeds of the opening rollers and the position of the grid bars – and thus the intensity of the cleaning – are automatically adjusted to the changing material fed (lot).

Due to the stepless and individual adjustment of grid devices for each opening roller, the machine can react to a wide variety of impurities. A 10 % higher speed of the second opening roller causes different speeds along the grids, while different sizes of waste can also be separated.

The WASTECONTROL waste sensor is now also integrated into the CL-X and makes sure that waste is reliably separated during production, which avoids unnecessary loss of valuable good fibers. The operator automatically receives a recommendation for the ideal setting via the machine's display and can implement it with just a few clicks.

The CL-X is the perfect and sustainable solution to meet today's demand for productivity, cleaning and energy efficiency.

Details matter: How Trützschler cylinder wires boost efficiency in Pakistan’s spinning sector

Pakistan’s textile industry, especially its spinning sector, is the backbone of the national economy and a vibrant hub of innovation. Today’s spinning mills face growing demands for efficiency, quality, and sustainability. From the serene northern valleys to the vibrant port city of Karachi in the south, mills like Suraj Cotton Mills, Liberty, and Nishat Chunian are turning to advanced solutions.

T-CAN – Revolutionizing can transport

In virtually all spinning mills, transporting sliver cans is still done manually. Rising labor costs, lack of operators and increasing quality requirements make this a growing challenge. With T-CAN, Trützschler introduces a practical solution: a fully automated can transport system that will be presented live at ITMA ASIA 2025 in Singapore.

Pre-Cleaner CL-X: The future of cotton cleaning

What if the future of cotton cleaning was already here – setting a new standard for cleaning efficiency, productivity and energy savings? That future has a name: CL-X. Since its market launch in 2022, the Pre-Cleaner CL-X has become a true bestseller, proving its value in several hundred customer applications worldwide. Now, new results from Türkiye demonstrate again how the Pre-Cleaner CL-X outperforms the competition.
