PWH-300 Heavy Duty Thermal Styrofoam Densifier

The PWH-300 is one of our original and most popular densifiers. It is a hand-fed machine that processes foam through a process of shredding while adding heat to densify and extrude densified purge blocks which become the final recyclable product. The PWH-300 densifies expanded polystyrene (EPS), expanded polyethylene (EPE) and expanded polypropylene (EPP).

Simple 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 styrofoam 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 styrofoam pieces into smaller, more manageable pieces for densification.

  5. Ready for Operation: Once both the auger and shredder are activated and operational, the PolyWiz Hot Melt Styrofoam Densifier is ready for use. You can begin feeding styrofoam waste into the hopper for processing.

Simplified Maintenance

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.

  • Easy to access grease fittings all in one convenient location
  • Easy to remove guard to access drive chain and apply lubricant
  • Easy to locate hole for simple gear oil application
  • And that's it! Machine maintenance is simple with Better Densifiers!

Feeding the Machine

Featuring a manual feeding system, our thermal densifiers offer operators full control over the input process. With this manual feeding mechanism, operators can carefully monitor and regulate the rate at which styrofoam waste is introduced into the densifier. This hands-on approach allows for flexibility in handling various types of styrofoam materials, ensuring efficient processing while minimizing the risk of jams or overloading.
