SETeMa BV, the Netherlands, has introduced the Porta-Wash roll-to-roll modular washing line that provides a long dwell time with minimal water content, minimal fresh water usage and moderate mechanical impact in line with the requirements of the diffusion wash process.

Each module is equipped with an adjustable vacuum system that can remove polluted water containing dyestuff and thickener residue from the cloth. Energy-efficient features include a counter-flow heat exchanger; airflow circulation at the vacuum system; and thermally isolated walls. A programmable logic controller controls washing speed, water temperature and vacuum per cloth type in each module.

Porta-Wash comes in three cloth widths; has a full-color, touch-screen interface; and offers options such as scroll rollers, tension control bars, two types of drying systems, and winding and unwinding systems.
