PWH-300 Heavy Duty Thermal Styrofoam Densifier

Keep large foam volumes moving with a machine built for demanding workloads. The American-made PWH-300 processes up to 300 pounds per hour, helping your business reclaim space, reduce haul-away costs, and recover value from clean foam waste.

More Capacity for Bulkier Foam

The PWH-300 combines a larger hopper with thermal densification for businesses handling substantial foam volumes or bulkier packaging pieces. It processes expanded polystyrene (EPS), expanded polyethylene (EPE), and expanded polypropylene (EPP).

This hand-fed machine shreds and heats clean, dry foam, reducing its volume by up to 90:1 and extruding dense purge. Optional form molds shape that material into manageable blocks for storage, handling, and sale.

Straightforward Operation

  1. Set Temperature: Begin by setting the desired operating temperature on the densifier control panel. This temperature will depend on the type and density of the foam being processed.
  2. Heating Process: Allow the system to heat up to the pre-set temperature. This process may take some time depending on the size of the densifier, as well as the initial temperature conditions.
  3. Auger Activation: As the system reaches the designated temperature, the auger will start automatically. This auger helps maintain a consistent flow of material for processing.
  4. Shredder Activation: Following the auger's initiation, the shredder component of the densifier will engage. The shredder is responsible for breaking down larger foam pieces into smaller, more manageable pieces for densification.
  5. Ready for Operation: Once both the auger and shredder are activated and operational, the PolyWiz Thermal Styrofoam Densifier is ready for use. You can begin feeding foam waste into the hopper for processing.

Maintenance Made Accessible

All grease fittings are strategically positioned on a single, user-friendly panel, making lubrication tasks effortless and convenient. This thoughtful design not only simplifies the maintenance process but also encourages operators to adhere to routine upkeep schedules. By streamlining maintenance procedures and providing easy access to critical components, we empower our clients to uphold the longevity and efficiency of their equipment, ultimately maximizing productivity and minimizing downtime.
