Graco 24P250 InvisiPac GS35 Quad Hot Melt Applicator with No Solenoid and Pt 100 RTD - I Module Spacing

InvisiPac GS35 Quad Plug-Free Hot Melt Applicator for Packaging Equipment

Configured with four applicator modules in an I-spacing layout, the Graco 24P250 InvisiPac GS35 quad hot melt applicator is designed for constant bead adhesive dispensing in high-speed case and carton sealing operations. The quad configuration supports consistent adhesive output across multiple dispense points, making it well suited for packaging lines that require uniform bead placement across wide cartons or multi-lane formats. Built with a plug-free adhesive path, the GS35 helps reduce 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 clean, stable adhesive flow throughout the dispensing system. This configuration operates without an onboard solenoid and incorporates a Pt 100 RTD to provide accurate temperature monitoring under system-controlled 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 24P250 is well suited for centrally controlled packaging lines, wide-format cartons, and multi-point constant bead applications where uniform spacing and system-level control are required.

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

Design Features of the GS35 24P250 Quad Hot Melt Applicator

• Designed for High-Speed Packaging Lines: Supports continuous constant-bead operation at speeds exceeding 3,500 cycles per minute, helping maintain throughput in demanding case and carton sealing environments.
• Built for Multi-Point Adhesive Application: Four dispensing modules apply consistent adhesive beads across multiple locations, making this applicator ideal for wide cartons and multi-lane packaging lines.
• Uniform I-Spacing Module Configuration: Fixed I-spacing keeps bead placement consistent across all four outlets, supporting accurate, repeatable sealing patterns in automated packaging equipment.
• Free-Flow, Plug-Resistant Adhesive Path: An open internal flow design minimizes adhesive stagnation and char formation, reducing the risk of nozzle plugging and unplanned maintenance.
• Internal Filtration Protects Critical Components: Heated manifold filtration and module-level filters capture debris and char before they reach the ball and seat, helping extend service intervals and maintain stable performance.
• System-Controlled Operation with Accurate Temperature Sensing: Configured without an onboard solenoid for centralized control and equipped with a Pt 100 RTD to deliver precise temperature feedback during continuous production.
