Graco 24U038 InvisiPac GS35 Low-Profile Quad Hot Melt Applicator with No Solenoid and Ni 120 RTD

InvisiPac GS35 Low-Profile Quad Applicator for High-Speed Packaging

The Graco 24U038 InvisiPac GS35 low-profile quad hot melt applicator is designed for constant bead adhesive dispensing in high-speed case and carton sealing operations where vertical clearance is limited. The low-profile quad configuration supports uniform adhesive output across four dispense points while maintaining a compact height for integration into space-constrained packaging equipment. Built with a plug-free adhesive path, the GS35 helps reduce nozzle plugging and adhesive char, supporting cleaner operation and improved uptime in continuous industrial packaging environments.

This configuration operates without an onboard solenoid and incorporates a Ni 120 RTD to provide accurate temperature monitoring under system-controlled operation. Reaching operating temperature in under 10 minutes and functioning in an air-opened, spring-closed mode at cycle speeds exceeding 3,500 cycles per minute, the 24U038 functions as a dependable adhesive dispenser and dispense valve solution for industrial packaging equipment, box sealing, and manufacturing adhesive systems. Used with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 delivers clean, consistent adhesive flow system-wide.
