Graco 25B036 InvisiPac GM100 Low-Profile Quad Hot Melt Applicator with 24 VDC Solenoid and Ni 120 RTD

Graco GM100 Low-Profile Quad Hot Melt Adhesive Applicator for Case Sealing

With a low-profile quad layout, the Graco 25B036 InvisiPac GM100 hot melt applicator is designed for high-speed case and carton sealing applications where vertical clearance is limited. The four-module configuration supports precise dot and stitch placement across multiple dispense points while maintaining consistent adhesive flow. Its plug-free design helps eliminate nozzle plugging and reduce adhesive char, minimizing downtime and supporting reliable operation in continuous packaging environments.

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. The applicator features a 24 VDC solenoid valve for dependable high-speed cycling and a Ni 120 RTD for accurate temperature monitoring. With a heat-up time of under 10 minutes and a compact low-profile quad design, this configuration is well suited for packaging line equipment and high-speed adhesive applications that require consistent multi-point dispensing in space-constrained layouts.

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

Benefits of a Low-Profile Quad GM100 Hot Melt Applicator Design
