Graco 24U030 InvisiPac GS35 Low-Profile Dual Hot Melt Applicator with 24 VDC Solenoid and Ni 120 RTD

Overview of GS35 24U030 InvisiPac Low-Profile Dual Adhesive Dispenser

The Graco 24U030 InvisiPac GS35 low-profile dual hot melt applicator is designed for constant bead adhesive dispensing in high-speed case and carton sealing operations where vertical space is limited. The dual-module, low-profile layout supports uniform adhesive output across two dispense points while maintaining a compact footprint for integration into space-constrained packaging machinery. Built with a plug-free adhesive path, the GS35 helps prevent nozzle plugging and reduce adhesive char, supporting cleaner operation and improved uptime in continuous packaging environments.

When used with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 delivers consistent, clean adhesive flow throughout the dispensing system. This configuration features a 24 VDC solenoid valve for responsive electronic control and a Ni 120 RTD for accurate temperature sensing 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 24U030 is well suited for packaging automation and industrial packaging equipment that require compact, dual-point constant bead dispensing with minimal maintenance.

High-Speed Dispensing Performance of the InvisiPac GS35 24U030

• Built for Space-Limited Packaging Lines: The low-profile dual-module design allows this GS35 applicator to fit into compact machine layouts while maintaining balanced adhesive output across two dispense points.
• Consistent Constant-Bead Output at High Speeds: Designed for case and carton sealing, the applicator delivers stable bead formation during continuous operation at cycle speeds over 3,500 cycles per minute.
• Reduced Maintenance Through Cleaner Adhesive Flow: A free-flow adhesive path with integrated heated filtration limits adhesive char and debris buildup, helping reduce nozzle plugging and unplanned downtime.
• Fast Warm-Up to Support Production Uptime: Heats to operating temperature in under 10 minutes, allowing packaging lines to restart quickly after shutdowns or changeovers.
• Accurate Control and Monitoring During Operation: A 24 VDC solenoid valve provides responsive actuation, while the Ni 120 RTD delivers reliable temperature feedback to support stable dispensing conditions.
• Optimized for the Graco InvisiPac System: Engineered to operate with InvisiPac Tank-Free Hot Melt Delivery Systems (HM10, HM25c, HM50), enabling clean, efficient adhesive delivery throughout packaging automation equipment.
