Graco 24U032 InvisiPac GS35 Low-Profile Dual Hot Melt Applicator with No Solenoid and Ni 120 RTD

GS35 Low-Profile Dual Hot Melt Applicator for End-of-Line Packaging Equipment

Suited for end-of-line packaging equipment where vertical clearance is limited and constant bead consistency is essential, the Graco 24U032 InvisiPac GS35 low-profile dual hot melt applicator delivers stable adhesive output across two dispense points without an onboard solenoid. The low-profile dual configuration integrates easily into space-constrained case and carton sealing machinery while maintaining uniform bead formation during high-speed operation. Built with a plug-free adhesive path, the GS35 helps reduce nozzle plugging and adhesive char, supporting cleaner performance and minimizing maintenance interruptions in continuous packaging environments.

Designed for operation within the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 supports clean, consistent adhesive delivery across the entire dispensing system. This configuration relies on external system control and incorporates a Ni 120 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 24U032 is well suited for end-of-line packaging equipment, packaging automation systems, and industrial box sealing applications that require compact, dual-point constant bead dispensing with system-level control.

Key Advantages of the Graco 24U032 GS35 Low-Profile Dual Applicator

• Consistent Constant-Bead Output: Engineered for continuous operation, the GS35 supports stable bead formation at speeds exceeding 3,500 cycles per minute, making it well suited for high-speed carton and box sealing applications.
• Low-Profile Design for Tight Packaging Layouts: The dual-module, low-profile configuration allows installation in space-limited end-of-line and case sealing equipment while maintaining even adhesive coverage across two dispense points.
• Reduced Char and Maintenance Requirements: A free-flow adhesive path combined with integrated heated filtration minimizes adhesive char and debris buildup, helping reduce nozzle plugging and routine maintenance interruptions.
• Fast Heat-Up for Efficient Line Starts: The applicator reaches operating temperature in under 10 minutes, supporting quicker startups and faster recovery after maintenance or line stops.
• External Control with Accurate Temperature Feedback: This configuration operates without an onboard solenoid and relies on system-level control, using a Ni 120 RTD to provide accurate temperature monitoring during production.
• Designed for InvisiPac System Integration: Compatible with Graco InvisiPac HM10, HM25c, and HM50 tank-free systems, supporting clean adhesive delivery across packaging automation and industrial packaging equipment.
