HiPerTherm Thermobonding Oven for Through-Air Bonding

The AUTEFA Solutions HiPerTherm double belt oven combines proven STRAHM Technology with advanced thermobonding, through-air bonding and drying technology for nonwovens. Its modular design can be adapted to a wide range of drying and thermobonding processes. In the standard configuration, HiPerTherm is equipped with the Bernoulli nozzle system, a robust drawer-type nozzle solution designed for demanding process conditions and raw materials ranging from fine, dust-like fibers to very long fibers.

For specific product requirements, a wide range of alternative nozzle systems is available. The Compress nozzle system incorporates calender rolls and is designed for the production of high-density nonwovens. For products with very low air permeability, the Reflex nozzle system ensures efficient and uniform thermal treatment even when processing materials with almost air-impermeable properties. As the complete nozzle boxes are designed as a drawer system, nozzle configurations can also be changed at a later stage with minimal installation effort.

The HiPerTherm double belt oven features a robust double-frame construction, high-density thermal insulation, magnetic operator doors, an intelligent integrated energy recovery system and state-of-the-art process controls. These design features support high throughput rates, excellent bonding uniformity and precise product calibration while contributing to optimized energy efficiency.

The combination of a highly stable mechanical design with uniform airflow and precise temperature distribution across the working width ensures consistent through-air bonding and thermobonding results. HiPerTherm is therefore ideally suited for demanding nonwoven production processes requiring high productivity, homogeneous thermal bonding and reproducible product quality.
