Graco 24P301 InvisiPac GS35 Dual Hot Melt Applicator with 24 VDC Solenoid and Ni 120 RTD

Overview of Graco 24P301 InvisiPac GS35 Dual Hot Melt Applicator

Built around consistent constant-bead performance, the Graco InvisiPac GS35 dual hot melt applicator (Model 24P301) supports reliable adhesive dispensing in high-speed case and carton sealing operations. The plug-free applicator design prevents nozzle plugging and reduces adhesive char, helping packaging lines maintain uptime and consistent bead quality during extended production runs. Integrated applicator filtering and a free-flow manifold minimize debris accumulation and support cleaner adhesive flow.

Fast startup and controlled operation define the GS35 platform, with the applicator reaching operating temperature in under 10 minutes. A heated-zone manifold filter removes char and contaminants during service, while an integrated module filter protects the ball and seat to maintain stable performance at cycle speeds up to 3,500 cycles per minute. Operating in an air-open, spring-close configuration, the GS35 is designed for use with the Graco InvisiPac Tank-Free Hot Melt Delivery System, delivering dependable performance in demanding packaging environments.

Graco 24P301 GS35 Dual Applicator Operating Characteristics

• Dual-Module Constant Bead Application: Two applicator modules deliver steady, uniform adhesive beads for case and carton sealing applications that require consistent coverage across multiple seal points.
• Reliable Electrical Actuation (24 VDC Solenoid): A 24 VDC solenoid provides responsive, repeatable valve operation, supporting stable dispensing at cycle speeds up to 3,500 cycles per minute.
• Accurate Temperature Feedback (Ni 120 RTD): The Ni 120 RTD supplies precise temperature monitoring, helping maintain consistent adhesive conditions during continuous production.
• Cleaner Adhesive Path with Reduced Char: A free-flow manifold and integrated applicator filtering minimize dead zones where adhesive char can form, reducing maintenance and unplanned downtime.
• Plug-Free Design for Improved Uptime: Built to eliminate nozzle plugging when used with the InvisiPac Tank-Free Hot Melt Delivery System, helping packaging lines run longer between service intervals.
• Fast Heat-Up for Quicker Line Starts: Reaches operating temperature in under 10 minutes, allowing faster startups after shutdowns, changeovers, or maintenance.
