Graco 24P309 InvisiPac GS35 Quad Hot Melt Applicator with No Solenoid and Ni 120 RTD - I Module Spacing

GS35 Quad Plug-Free Adhesive Dispenser for Packaging Equipment

The Graco 24P309 InvisiPac GS35 quad hot melt applicator is designed for constant bead adhesive dispensing in high-speed case and carton sealing operations that require four-point application without onboard solenoid control. The quad-module configuration with I-style spacing supports consistent bead placement across multiple dispense locations, making it well suited for packaging lines handling wide cartons or multi-lane formats. Built with a plug-free adhesive path, the GS35 helps minimize 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 delivers stable, system-controlled adhesive flow across the entire dispensing system. This configuration operates without a solenoid and uses a Ni 120 RTD for accurate temperature feedback under external control. With a heat-up time of under 10 minutes, air-opened, spring-closed operation, and cycle speeds exceeding 3,500 cycles per minute, the 24P309 is well suited for centrally controlled packaging lines that require consistent four-point bead application across wide-format cartons and high-speed sealing operations.

No-Solenoid Design Benefits of the GS35 24P309 Quad Applicator

• Designed for InvisiPac Tank-Free Systems: Compatible with Graco InvisiPac HM10, HM25c, and HM50 systems for clean, tank-free adhesive delivery.
• Four-Point Constant Bead Dispensing: Quad-module design applies adhesive at four locations simultaneously, supporting consistent bead placement for wide cartons and multi-lane packaging lines.
• Smooth Internal Adhesive Flow: Free-flow internal design reduces adhesive buildup and helps prevent nozzle plugging, supporting cleaner operation and longer run times.
• System-Controlled Operation (No Solenoid): Built without an onboard solenoid for use in centrally controlled systems and integrated packaging lines.
• Ni 120 RTD Temperature Monitoring: Integrated Ni 120 RTD provides accurate temperature feedback to help maintain stable adhesive application during production.
• Fast Heat-Up and High-Speed Performance: Reaches operating temperature in under 10 minutes and supports cycle speeds up to 3,500 cycles per minute.
