Delivery comprises multiple save-alls with single and double doctor solutions.

Well-designed save-alls are essential to get the full benefits from increased dewatering and ensure efficient water discharge with perfect rewetting prevention. Results are higher dryness after press, better moisture profiles and reduced draw from press to dryer. Runtech’s high-quality composite doctor beams and CompoAdapt blade holders are light and have excellent stiffness and strength properties.
This enables easy installation while reaching the highest reliability and performance results. Papier-u. Kartonfabrik Varel operates four paper and board machines with an annual capacity of 930,000 tons on its site in Varel, Lower Saxony.
