Graco 25B024 InvisiPac GM100 Single Slim Hot Melt Applicator with 24 VDC Solenoid and Ni 120 RTD

Graco 25B024 InvisiPac GM100 Single Slim Adhesive Dispenser Overview

The Graco InvisiPac 25B024 GM100 is a single slim hot melt adhesive applicator designed for controlled adhesive dispensing in high-speed case and carton sealing environments. As an InvisiPac applicator, it supports precise dot and stitch application while operating as a compact hot melt dispenser. Its plug-free design eliminates nozzle plugging and reduces adhesive char, helping improve system cleanliness and reduce unplanned downtime. The applicator uses a 24 VDC solenoid valve for responsive operation and a Ni 120 RTD to provide accurate temperature feedback during continuous production.

Designed for use with the Graco InvisiPac Tank-Free Hot Melt Delivery System, the GM100 is compatible with HM10, HM25c, and HM50 systems to support clean adhesive delivery at the system level. Its slim, single-module construction allows straightforward installation in tight machine layouts, and with a heat-up time of under 10 minutes, the applicator helps production lines reach operating temperature quickly. This makes it a dependable adhesive dispenser and dispense valve solution for box sealing and industrial packaging applications.

High-Speed Case and Carton Sealing Advantages of the Graco 25B024

• Compact Single-Module Layout: A slim, single-module construction supports straightforward installation in tight machine frames without sacrificing adhesive output stability.
• Temperature Sensing and Actuation: Adhesive flow is controlled using a 24 VDC solenoid valve with a Ni 120 RTD, providing steady electrical response and reliable thermal feedback during operation.
• Clean Adhesive Delivery: By eliminating internal dead zones, the InvisiPac™ adhesive path reduces char formation and prevents nozzle plugging during extended production runs.
• Startup Readiness: The applicator reaches operating temperature in roughly 10 minutes, allowing lines to return to production quickly following startup or routine maintenance.
• Dispensing Control Method: Air-opened, air-closed operation regulates adhesive output during high-speed cycling without relying on mechanical spring return.
• Dot and Stitch Dispensing Capability: Supports precise dot and stitch adhesive patterns required for high-speed case and carton sealing operations.
