SolarMax - maximum dewatering, marginal costs -


Tests at the Voith Paper Technology Center (PTC) in Heidenheim, Germany, and initial field tests at customer sites have clearly shown that using newly developed suction roll covers and felts specifically selected for their use can achieve increases in dry content of up to 1.5 % - without the need for large investment costs.

The optimized groove technology applied to the polyurethane roll covers by Voith Paper leads to significantly deeper and wider grooves, resulting in shortened flow paths for the extracted water. This increased capacity enables larger quantities of water to be removed quickly and efficiently.

The larger quantities of water and resultant increased dry content are made possible by the structurally engineered felt with optimized absorptive capacity. The structural treatment also enables the felt to bridge the open spaces created by the grooving, reducing the risk of marking the paper.

This combination of suction roll cover and felt - SolarMax - offers maximum dewatering of the paper web and thus the highest possible dry content.

Voith Paper is a division of the Voith Group and the leading partner to and pioneer in the paper industry. Through constant innovations, Voith Paper is optimizing the paper manufacturing process, focusing on developing resource-saving products to reduce the use of energy, water, and fibers.
