Nonwoven / Hygiene

Foreign materials and contamination are particularly unwelcome in the manufacture of personal care products such as plasters, cloths, nappies and napkins. LTG filtration technology and fans ensure that you meet the highest standards.
Waste material remaining from production, such as hygroscopic granulates and cellulose fibres in the case of nappies, is collected and separated with absolute reliability. Our systems operate continuously and without pressure surges, permitting recyclable materials to be returned to the production process. The highly efficient separation process reduces your energy and operating costs. Our modular system lets you combine the filter stages to suit your requirements. LTG also offers filter components for high temperatures or aggressive media.
Relative humidity is frequently a critical factor in the manufacture of textiles and nonwovens for personal care products. Our humidification systems can give you perfect control of climate conditions.
When you produce nonwoven material, our tangential fans help you to lay and compact the fibres with the best possible control. The advantages: LTG tangential fans generate a perfectly even air flow over the entire width of the material, ensuring constant process parameters, high nonwoven material quality and a large throughput.
We can offer a modular, cost-effective solution for your application. Our engineering services will help you design your air system, comply with emission limits and control production parameters like temperature and humidity. To ensure maximum reliability we can carry out preliminary tests at our technical centre or right at your Location.

LTG Filtration Technology products have proved their worth in the personal care and medical sectors over many years now. Our product range has a modular structure, allowing you to adapt all of the process stages to your application. Our compact filter unit CFU combines the individual products and can consist of different filter stages depending on the design. For example, these systems can be equipped with a TVM pre-filter unit and a fine filter like the CompactDrum Filter®. Reusable filtered materials are conveyed to the respective secondary circuits, where they are efficiently separated by our ZSA/ZSB/ZSC centrifugal separators, FKA/FKC fibre compactors or CPS compacting power screws. It is also possible to convey these materials directly to a silo or return them to the production process.

Our product portfolio also includes LTG fans for air treatment in all designs and sizes. Among those of special importance for nonwovens and textiles are our highly efficient LTG axial-flow fans and high-quality LTG centrifugal fans, which are mainly used for conveying primary air.

Our conveying fans in the M./5 RU..MS series were specially developed for handling concentrations of dust and fibres in the secondary circuits of filter systems. By selecting special, highly wear-resistant material pairings, we have made them very durable and minimised the maintenance requirements.

We also offer LTG tangential fans, which distribute air very evenly over large areas. Finally, LTG's product range includes tangential fans, which distribute air very evenly over large areas, permitting efficient and high-quality drying in conveyor systems or throughput processes.

Our engineering services are available if you need help in designing air and heating systems and have to select exact values of parameters that are important for your processes, such as air temperature, heating and cooling capacities, and humidity. We'll work with you to develop an optimum design and verify it using state-of-the-art aids such as computational fluid dynamics (CFD) and tests at our technical centre.
