Graco 25B033 InvisiPac GM100 Low-Profile Quad Hot Melt Applicator with 24 VDC Solenoid and Pt 100 RTD

InvisiPac 25B033 GM100 Low-Profile Quad Adhesive Dispenser Overview

Designed to deliver four-point adhesive output in space-constrained packaging lines, the Graco 25B033 InvisiPac GM100 low-profile quad hot melt applicator provides precise adhesive placement across multiple dispense locations without sacrificing accessibility or performance. The low-profile quad configuration supports accurate dot and stitch application while maintaining consistent adhesive flow. Its plug-free design helps eliminate nozzle plugging and reduce adhesive char, minimizing downtime and supporting reliable operation in high-speed case and carton sealing 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 Pt 100 RTD for accurate temperature monitoring. With a heat-up time of under 10 minutes and a low-profile quad layout, this configuration is ideal for industrial packaging equipment and packaging automation systems that require compact, multi-point adhesive application with consistent performance.
