Graco 24U033 InvisiPac GS35 Low-Profile Quad Hot Melt Applicator with 24 VDC Solenoid and Pt 100 RTD

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

Built for high-speed packaging lines where vertical clearance is limited and multi-point constant bead application is required, the Graco 24U033 InvisiPac GS35 low-profile quad hot melt applicator delivers consistent adhesive output across four dispense locations. The low-profile quad configuration allows integration into space-constrained case and carton sealing equipment while maintaining uniform bead formation across multiple application points. Its plug-free adhesive path helps prevent nozzle plugging and reduce adhesive char, supporting cleaner operation and improved uptime in continuous industrial packaging environments.

Designed for use with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 supports clean, stable adhesive delivery throughout the dispensing system. This configuration features a 24 VDC solenoid valve for responsive electronic control and a Pt 100 RTD for accurate temperature monitoring during operation. With a heat-up time of under 10 minutes, air-opened, spring-closed operation, and cycle speeds exceeding 3,500 cycles per minute, the 24U033 is well suited for low-clearance packaging lines that require reliable four-point constant bead dispensing.

This model is part of the InvisiPac GS35 applicator series. View all available GS35 configurations here.
