Graco 24U037 InvisiPac GS35 Low-Profile Quad Hot Melt Applicator with 110 VAC Solenoid and Ni 120 RTD

Low-Profile GS35 Applicator with Four Modules for Graco InvisiPac Systems

The Graco 24U037 InvisiPac GS35 low-profile quad hot melt applicator delivers consistent adhesive output across multiple dispense locations in case and carton sealing environments. 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 improved uptime in continuous industrial packaging applications.

This configuration is equipped with a 110 VAC solenoid valve for dependable electrical actuation and a Ni 120 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 24U037 functions as a reliable adhesive dispenser and dispense valve solution for packaging automation, industrial packaging equipment, and high-speed box and carton sealing applications. When integrated with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 provides clean, stable adhesive delivery throughout the dispensing system.

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

Quad-Module Adhesive Application Benefits of the InvisiPac GS35 24U037

• 110 VAC Solenoid with Ni 120 RTD Feedback: Uses a 110 VAC solenoid for reliable valve actuation while the Ni 120 RTD provides accurate temperature feedback during operation.
• Four-Point Constant Bead Dispensing: Applies adhesive at four locations simultaneously for consistent sealing on wide cartons and multi-lane packaging lines.
• Low-Profile Quad Configuration: Four dispense modules in a reduced-height design allow installation in packaging equipment with limited vertical clearance.
• Clean, Free-Flow Adhesive Path: Internal adhesive flow design helps reduce buildup and nozzle plugging to support cleaner operation and less downtime.
• Fast Heat-Up and High-Speed Operation: Reaches operating temperature in under 10 minutes and supports cycle speeds up to 3,500 cycles per minute.
• Designed for InvisiPac Tank-Free Systems: Built for use with Graco InvisiPac hot melt delivery systems to support clean adhesive delivery and reduced maintenance.
