Product overview
MICRON+ DRUM 200 is a drum follower/unloader designed for 200 L (55 gal) hot-melt adhesive drums, providing homogeneous melting, reliable sealing and a constant adhesive supply for demanding industrial applications. The unit features air-injection automatic drum ejection and a modular design to adapt to specific production needs.

Key functions and technology

• Homogeneous melting and effective sealing of drum contents.
• Automatic drum ejection via air injection for safe and efficient drum changes.
• Integrated ADA weight-control system for precise flow regulation by automatically adjusting pump speed according to required adhesive amount.
• All control functions integrated into Meler's electronic platform for process stability and repeatability.

Integration and operation
MICRON+ DRUM 200 integrates easily with main machines using multiple communication protocols. The Tandem option (standard) allows two Drum 200 units to operate in parallel to avoid production downtime during drum replacement. Communication between follower plates is simplified by a pre-installed cable harness with connector.

Adaptability and options

• Different pump sizes (single and double pump configurations).
• Various input voltages (e.g. 400V / 480V options).
• Measurement units adaptable to geographic markets.
• Fixed or variable pump-speed control.
• Different melting discs (smooth, radial fins, parallel fins) depending on adhesive type and required melting ratio.

Benefits

• High energy efficiency.
• Configurable, modular design for process adaptation.
• Easy access for operation and maintenance.
• Simple installation and full connectivity for line integration.
• Enables use of special adhesives (PUR, PSA, EVA).
