Graco 24P079 InvisiPac GS35 Quad Hot Melt Applicator with 24 VDC Solenoid and Pt 100 RTD - II Module Spacing

Graco GS35 Quad Hot Melt Adhesive Applicator for Constant Bead Applications

Intended for high-speed packaging lines that require four-point constant bead adhesive application, the Graco 24P079 InvisiPac GS35 quad hot melt applicator delivers consistent adhesive output across multiple dispense locations in case and carton sealing operations. The quad-module configuration with II-style spacing allows wider separation between application points, making it well suited for larger cartons and packaging equipment that requires precise bead placement across broader formats. Built with a plug-free adhesive path, the GS35 helps minimize nozzle plugging and adhesive char, supporting cleaner operation and reduced maintenance 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 production. 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 24P079 is well suited for large-format cartons, wide-lane packaging equipment, and high-speed constant bead applications where extended module spacing and uniform adhesive output are critical.

Quad Configuration Features of the InvisiPac GS35 24P079

• Quad-Point Constant Bead Coverage: Four applicator modules deliver uniform, continuous adhesive beads across multiple dispense locations, supporting wide-format cartons and multi-lane packaging lines.
• II Module Spacing for Wider Layouts: Increased spacing between modules accommodates larger cartons and broader application patterns without compromising bead consistency or placement accuracy.
• Char-Reducing Free-Flow Adhesive Path: A plug-free manifold design minimizes dead zones where adhesive can degrade, helping reduce char buildup and maintain cleaner operation over long production runs.
• Integrated Filtration for Cleaner Dispensing: Heated-zone manifold filtration and internal module filtering capture debris and char before it reaches critical components, reducing maintenance interruptions.
• Fast Heat-Up with Stable High-Speed Operation: Reaches operating temperature in under 10 minutes and supports constant bead dispensing at cycle speeds exceeding 3,500 cycles per minute.
• Accurate Temperature Control and Actuation: Equipped with a 24 VDC solenoid valve and Pt 100 RTD to provide responsive control and precise temperature monitoring during continuous operation.
