Graco 24U035 InvisiPac GS35 Low-Profile Quad Hot Melt Applicator with No Solenoid and Pt 100 RTD

Overview of Graco GS35 Low-Profile Quad Applicator for High-Speed Packaging

Configured in a low-profile quad-module layout, the Graco 24U035 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 four-module, low-profile configuration allows uniform adhesive output across multiple dispense points while fitting into space-constrained packaging equipment. Built with a plug-free adhesive path, the GS35 helps prevent nozzle plugging and reduce adhesive char, supporting cleaner operation and minimizing maintenance in continuous production environments.

This configuration operates without an onboard solenoid and incorporates a Pt 100 RTD for accurate temperature monitoring under system-controlled 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 24U035 is well suited for low-clearance packaging lines that require reliable four-point constant bead dispensing. When integrated with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 delivers clean, stable adhesive flow across the entire dispensing system.
