Graco 24U036 InvisiPac GS35 Low-Profile Quad Hot Melt Applicator with 24 VDC Solenoid and Ni 120 RTD

GS35 Low-Profile Quad Applicator for Graco InvisiPac Hot Melt System

Designed for high-speed packaging lines where vertical clearance is limited and four-point constant bead application is required, the Graco 24U036 InvisiPac GS35 low-profile quad hot melt applicator delivers consistent adhesive output across multiple dispense locations in case and carton sealing operations. The low-profile quad configuration allows integration into space-constrained packaging equipment while maintaining uniform bead formation across all four modules. Its plug-free adhesive path helps minimize nozzle plugging and adhesive char, supporting cleaner operation and reducing maintenance interruptions in continuous industrial packaging environments.

This configuration features a 24 VDC solenoid valve for responsive electronic 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 24U036 is well suited for low-clearance box sealing and packaging automation systems 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.
