Graco 25B030 InvisiPac GM100 Low-Profile Dual Hot Melt Applicator with 24 VDC Solenoid and Ni 120 RTD

Graco GM100 Low-Profile Dual Plug-Free Hot Melt Applicator for Industrial Packaging Equipment

The Graco 25B030 InvisiPac GM100 is a low-profile dual hot melt adhesive applicator developed for high-speed case and carton sealing operations where vertical space is limited. The dual-module configuration provides controlled, consistent adhesive output while supporting accurate dot and stitch placement. Its plug-free design helps eliminate nozzle plugging and reduce adhesive char, minimizing downtime and maintaining clean operation in continuous industrial packaging environments.

The applicator features a 24 VDC solenoid valve for dependable high-speed cycling and a Ni 120 RTD for precise temperature monitoring, supporting stable operation during continuous production. When used with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GM100 supports clean adhesive delivery throughout the dispensing system. With a heat-up time of under 10 minutes and a compact low-profile dual layout, this applicator functions as a reliable adhesive dispenser and dispense valve solution for packaging automation and industrial packaging equipment.

Additional InvisiPac GM100 applicator configurations are available.

Key Advantages of the Graco 25B030 InvisiPac GM100 Low-Profile Dual Applicator

• Fast Start-Up: Heats to operating temperature in about 10 minutes, helping packaging lines get back into production quickly after startup or maintenance.
