Graco GSC079 InvisiPac GM100 Quad Hot Melt Applicator with 24 VDC Solenoid and Pt 100 RTD - II Module Spacing

Overview of Graco GSC079 GM100 InvisiPac Quad Plug-Free Hot Melt Applicator

Designed to support four-point adhesive application, the Graco GSC079 InvisiPac GM100 quad hot melt applicator delivers consistent adhesive output across multiple dispense locations in high-speed carton and case sealing operations. The four-module configuration enables precise dot and stitch placement while maintaining uniform adhesive flow across all application points. Its plug-free design helps prevent nozzle plugging and reduce adhesive char, minimizing downtime and promoting cleaner operation in continuous packaging environments.

When integrated with the Graco InvisiPac Tank-Free Hot Melt Delivery System—including HM10, HM25c, and HM50 models—the GM100 integrates seamlessly into industrial packaging equipment. The applicator is equipped with a 24 VDC solenoid valve for reliable high-speed cycling and a Pt 100 RTD for accurate temperature monitoring. With a heat-up time of under 10 minutes and II-style module spacing (contact us for dimensions), this quad configuration is well suited for packaging automation systems that require precise module alignment and consistent high-speed adhesive application.

Features & Benefits of the Graco GSC079 InvisiPac GM100 Quad Applicator

• Free-Flow Adhesive Path: The InvisiPac™ manifold design and integrated filtration eliminate internal dead zones, helping reduce adhesive char formation and prevent nozzle plugging during continuous operation.
• Electrical Actuation and Sensing: Uses a 24 VDC solenoid valve together with a Pt 100 RTD to maintain stable valve response and accurate temperature feedback at high cycle rates.
• Pneumatic Dispensing Control: Operates using air-opened, air-closed actuation to regulate adhesive output consistently across all four modules.
• Four-Point Adhesive Output: A quad-module configuration delivers adhesive from four dispense locations within a single applicator body, supporting multi-point sealing requirements on high-speed packaging lines.
• II-Style Module Spacing: Built with II-style module spacing (contact us for dimensions) to allow defined separation between modules where machine layouts require specific dispense point alignment.
• High-Speed Carton Sealing Use: Functions as a carton sealing applicator within industrial packaging equipment, supporting reliable dot and stitch application in demanding production environments.
