Graco 24U031 InvisiPac GS35 Low-Profile Dual Hot Melt Applicator with 110 VAC Solenoid and Ni 120 RTD

Product Details for Graco 24U031 InvisiPac GS35 Low-Profile Dual Hot Melt Applicator

Configured in a low-profile dual-module layout, the Graco 24U031 InvisiPac GS35 hot melt applicator is designed for constant bead adhesive dispensing in high-speed case and carton sealing operations where vertical clearance is limited. The compact dual configuration delivers consistent adhesive output across two dispense points while maintaining a reduced height for integration into space-constrained packaging equipment. Built with a plug-free adhesive path, the GS35 helps limit nozzle plugging and adhesive char, supporting cleaner operation and reduced maintenance demands in continuous production environments.

When integrated with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 provides clean, stable adhesive delivery across the entire dispensing system. This configuration is equipped with a 110 VAC solenoid valve for dependable electrical control and a Ni 120 RTD to support accurate temperature monitoring during operation. Reaching operating temperature in under 10 minutes and operating in an air-opened, spring-closed mode at cycle speeds exceeding 3,500 cycles per minute, the 24U031 functions as a reliable adhesive dispenser and dispense valve solution for packaging automation and industrial packaging equipment.
