Graco 24U029 InvisiPac GS35 Low-Profile Dual Hot Melt Applicator with No Solenoid and Pt 100 RTD

Low-Profile GS35 Dual Hot Melt Applicator for Space-Constrained Packaging Lines

Built for reliable constant bead adhesive dispensing in space-constrained packaging equipment, the Graco 24U029 InvisiPac GS35 low-profile dual hot melt applicator delivers stable, uninterrupted adhesive flow across two dispense points. The low-profile dual configuration is suited for high-speed case and carton sealing applications where vertical clearance is limited, while the plug-free adhesive path helps prevent nozzle plugging and minimize adhesive char. This design supports cleaner operation and improved uptime in continuous packaging environments where maintenance interruptions must be kept to a minimum.

Designed for use within the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 enables clean adhesive delivery across the entire dispensing system. This configuration operates without an onboard solenoid and uses a Pt 100 RTD to provide accurate temperature monitoring during operation. Reaching operating temperature in under 10 minutes and functioning in an air-opened, spring-closed mode at cycle speeds exceeding 3,500 cycles per minute, the 24U029 serves as a dependable adhesive dispenser and dispense valve solution for industrial packaging equipment and packaging automation applications.

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

Low-Profile Dual Design Features of the Graco 24U029 GS35

• Optimized for Limited Vertical Clearance: The low-profile dual-module GS35 design allows installation in space-restricted packaging equipment while maintaining stable adhesive delivery across two dispense points.
• Consistent Constant-Bead Performance: Engineered for high-speed case and carton sealing, the applicator maintains uniform bead output during continuous operation at cycle speeds exceeding 3,500 cycles per minute.
• Cleaner Adhesive Flow with Reduced Maintenance: A plug-free adhesive path combined with integrated heated-zone filtration minimizes adhesive char and debris buildup, helping reduce nozzle plugging and unplanned downtime.
• Rapid Heat-Up for Faster Line Readiness: Reaches operating temperature in under 10 minutes, allowing production lines to start quickly after maintenance, changeovers, or system restarts.
• External Actuation with Precise Temperature Monitoring: Configured without an onboard solenoid, this model uses a Pt 100 RTD to deliver accurate temperature feedback for stable adhesive control in externally actuated systems.
• Designed for System-Level InvisiPac Performance: When paired with the Graco InvisiPac Tank-Free Hot Melt Delivery System (HM10, HM25c, HM50), the GS35 supports clean, efficient adhesive delivery throughout demanding packaging automation environments.
