Meler Micron+ Drum 200 Hot Melt Drum Unloader – 55 Gallon

High-Capacity Hot Melt Drum Unloader for Continuous Production Environments

The Meler Micron+ Drum 200 is a high-capacity hot melt drum unloader designed for processing 55 gallon (200 liter) adhesive drums in demanding production environments. Engineered for use with a wide range of hot melt adhesives including PSA, EVA, and polyolefin (PO), it delivers a steady, controlled adhesive supply for high-throughput applications where uptime and consistency are critical.

Engineered with sequential zone heating and a thermally balanced melting plate, the Micron+ Drum 200 maintains uniform temperature across the adhesive surface to ensure stable viscosity and efficient melting. Integrated controls with real-time monitoring and tandem operation capability enable continuous production during drum changeovers, reducing downtime and maintaining consistent adhesive flow.

For lower-volume applications or more compact system requirements, see the Micron+ Drum 20 hot melt pail unloader.
