Compact pulper fitting under paper machines for immediate processing of wet broke and dry trim fiber recovery.
The Under Pulper (PUP) is designed for continuous repulping of wet broke directly under the paper machine, ensuring efficient fiber recovery without interrupting production.
Engineered for space-constrained installations, this compact pulper handles wet broke at the machine discharge, minimizing fiber loss and reducing waste handling costs.
Ideal for paper and board mills requiring reliable broke recovery with seamless integration into existing stock systems.
