WEIMA's Puehler - Highly Efficient
Dewatering and Compression Presses

An economical solution for filled or empty packaging such as cans, plastic bottles, tubes, yogurt pots is here. The WEIMA - PUEHLER addresses scrap material and food and beverage waste created when incorrect packaging, incorrect labels, and breakages occur in production phases. The machines also provide draining and compression of packaging waste such as used labels and have applications in waste water treatment facilities to drain and compress removed fine parts.

The WEIMA - PUEHLER series contains label presses, can presses, recycling and packaging presses, rework presses, and chip presses. Highly efficient machines for businesses and facilities looking to reduce liquid weight and volumes to save on waste management costs. 

Drain, shred and compress filled packaging in one step! That is, dewater, separate waste streams (liquid, labels, packaging) and compact cans and containers. 

Installation only requires a water connection and is designed for minimal down time thanks to hydraulic oil cooling using the heat exchanger method. This is more hygienic and does not need cleaning. The water can be repurposed to dilute extruded material and minimize foam development.
