Graco 24P078 InvisiPac GS35 Quad Hot Melt Applicator with 110 VAC Solenoid and Pt 100 RTD - I Module Spacing

InvisiPac GS35 Hot Melt Applicator with Four Modules for Industrial Packaging

Configured with four applicator modules in an I-spacing layout, the Graco 24P078 InvisiPac GS35 quad hot melt applicator is designed for constant bead adhesive dispensing in high-speed case and carton sealing operations. The quad-module configuration supports uniform adhesive output across multiple dispense points, making it well suited for wide-format cartons and packaging lines that require consistent bead placement across several application locations. 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.

When integrated with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 enables clean, stable adhesive delivery across the entire dispensing system. This configuration is equipped with a 110 VAC solenoid valve for dependable electrical actuation and a Pt 100 RTD to provide 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 24P078 functions as a reliable adhesive dispenser and dispense valve solution for packaging line equipment, manufacturing adhesive systems, and high-speed multi-point carton sealing applications.

Key Design Features and Benefits of the InvisiPac GS35 24P078

• Multi-Point Adhesive Application for Wide Packaging Lines: The four-module GS35 configuration with I-spacing allows consistent bead placement across multiple dispense locations, making it ideal for wide cartons and multi-lane case sealing operations.
• Built for Continuous Constant-Bead Operation: Designed specifically for constant bead dispensing, the GS35 maintains uniform adhesive output at speeds above 3,500 cycles per minute, supporting high-throughput packaging environments.
• Cleaner Adhesive Path with Reduced Plugging Risk: A free-flow manifold, heated-zone filtration, and integrated module filters work together to limit adhesive char and debris buildup, helping prevent nozzle plugging and reduce maintenance frequency.
• Rapid Startup to Support Line Efficiency: The applicator reaches operating temperature in under 10 minutes, allowing production lines to return to operation quickly after shutdowns, changeovers, or service intervals.
• Accurate Control and Monitoring: This model is equipped with a 110 VAC solenoid valve for reliable actuation and a Pt 100 RTD for precise temperature feedback, supporting stable adhesive performance during extended production runs.
• Easy Integration into High-Speed Packaging Equipment: The GS35 quad configuration is designed to drop into existing case and carton sealing machinery without extensive mechanical modification.
