Dewatering elements for tissue machines

Increased production capacity and improved quality with proper initial drainage

Dewatering equipment beneath the forming fabric helps drain water from the stock and conduct it away into the whitewater system. Proper initial drainage is important whether your priority is to increase production capacity or improve quality, or both. Valmet offers a comprehensive range of polyethylene and ceramic dewatering elements to suit virtually all positions and OEM machine configurations.

Easy and safe installation

Low friction

Fast turn-around time

Available for all OEM designs
