Graco 25B075 InvisiPac GM100 Dual Hot Melt Applicator with 24 VDC Solenoid and Pt 100 RTD

InvisiPac 25B075 GM100 Dual Adhesive Dispenser for Industrial Packaging Equipment

Graco's 25B075 InvisiPac GM100 is a dual hot melt adhesive applicator designed to deliver two adhesive outputs from a single, compact applicator body. With dual modules operating together, this hot melt dispenser supports controlled adhesive application for case and carton sealing processes that require precise placement across multiple points. The plug-free design eliminates nozzle plugging and reduces adhesive char, helping minimize downtime while maintaining consistent adhesive output. The applicator operates using a 24 VDC solenoid valve and a Pt 100 RTD, providing reliable actuation and accurate temperature monitoring during continuous production.

Its dual-module construction allows the GM100 to integrate easily into industrial packaging equipment, where it functions as a dependable InvisiPac applicator, adhesive dispenser, and dispense valve for box sealing applications. Designed for use with the Graco InvisiPac Tank-Free Hot Melt Delivery System, the GM100 is compatible with HM10, HM25c, and HM50, supporting clean adhesive delivery across the dispensing system. With a heat-up time of under 10 minutes, the applicator helps production lines start faster and maintain throughput in demanding packaging environments.

This model is part of the Graco InvisiPac GM100 applicator series. View all available GM100 configurations here.

Dual-Module Performance Advantages of the Graco 25B075 Adhesive Dispenser

• High-Speed Cycling: Each module supports rapid dot and stitch dispensing at speeds exceeding 10,000 cycles per minute, maintaining consistent adhesive placement across parallel seal points.
• Plug-Free Adhesive Path: The InvisiPac™ free-flow manifold and integrated filtering prevent nozzle plugging and reduce adhesive char by eliminating internal dead zones.
• Electrical Actuation and Sensing: A 24 VDC solenoid valve paired with a Pt 100 RTD provides reliable valve response and stable temperature feedback during continuous production.
• Dual-Module Output Configuration: Two adhesive modules operate within a single applicator body, allowing adhesive to be applied at multiple points without adding additional applicators to the machine.
• Pneumatic Control Method: Adhesive flow is controlled using air-opened, air-closed operation, enabling repeatable output without reliance on mechanical return springs.
• Independent High-Speed Cycling: Each module supports rapid dot and stitch dispensing at speeds exceeding 10,000 cycles per minute, maintaining consistent adhesive placement across parallel seal points.
