Meler Micron+ Drum 20 Hot Melt Pail Unloader – 5 Gallon

Compact Hot Melt Pail Unloader for Low-Volume, Precision Applications

The Meler Micron+ Drum 20 is a compact hot melt pail unloader designed for processing 5 gallon (20 liter) pails in low-volume, precision-controlled applications. Engineered for use with a range of hot melt adhesives including PSA, EVA, and polyolefin (PO), it delivers consistent adhesive flow while reducing material waste and maintaining stable adhesive properties. Sequential zone heating and a thermally balanced melting plate maintain uniform temperature across the adhesive surface, ensuring stable viscosity and controlled output.

Integrated controls with real-time monitoring allow precise adjustment of temperature and pump performance, while flexible pump configurations support a wide range of application requirements. Its compact footprint makes it ideal for intermittent production, specialty adhesives, and operations where a full-size system would be oversized.

Key Advantages of the Micron+ Drum 20 — 5 Gallon Hot Melt Pail Unloader

• Sequential Zone Heating System: Heats adhesive progressively through controlled zones to maintain stable temperature, reducing thermal degradation and ensuring consistent application performance.
• Thermally Balanced Melting Plate: Maintains uniform heat distribution across the adhesive surface to support stable viscosity and controlled, repeatable output.
• Configurable Pump Output: Supports multiple pump sizes with single or double pump configurations to match application-specific flow rates and dispensing requirements.
• Integrated Control System with Real-Time Monitoring: Displays temperature, pump speed, and system status, allowing precise adjustment and consistent process control during operation.
• Flexible Melting Plate Options: Available with smooth or radial fin discs to optimize melt rate based on adhesive type and throughput requirements.
• Compact, Serviceable Design: Space-efficient footprint with accessible components simplifies installation, reduces maintenance time, and supports use in space-constrained production areas.
