Graco 24P254 InvisiPac GS35 Quad Hot Melt Applicator with No Solenoid and Pt 100 RTD - II Module Spacing

GS35 24P254 Quad Hot Melt Adhesive Applicator for Bead Dispensing

The Graco 24P254 InvisiPac GS35 quad hot melt applicator is designed for high-speed packaging lines that require four-point constant bead adhesive application with wider dispense spacing. The quad-module configuration with II-style spacing accommodates larger cartons and broader packaging formats, making it well suited for industrial packaging equipment where precise bead placement across wider layouts is required. Its plug-free adhesive path helps reduce nozzle plugging and adhesive char, supporting cleaner operation and minimizing maintenance interruptions in continuous production environments.

Built for use with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 provides clean, stable adhesive delivery throughout the dispensing system. This configuration operates without an onboard solenoid and relies on external system control, incorporating a Pt 100 RTD for accurate temperature monitoring during operation. With a heat-up time of under 10 minutes and air-opened, spring-closed operation at cycle speeds exceeding 3,500 cycles per minute, the 24P254 is well suited for wide-format cartons, system-controlled packaging lines, and multi-point constant bead applications where consistent spacing and high throughput are essential.

Quad II-Spacing Advantages of the InvisiPac GS35 24P254

• Four-Module Quad Applicator Design: Delivers consistent constant-bead adhesive application across four dispense points, supporting multi-lane and wide-format case and carton sealing operations.
• Extended II-Spacing for Wide Cartons: Increased spacing between modules accommodates larger box formats and broader sealing patterns where standard spacing is insufficient.
• Optimized for System-Controlled Operation: Configured without an onboard solenoid, allowing centralized control through the adhesive system for synchronized dispensing across multiple applicators.
• Plug-Resistant Adhesive Flow Path: A free-flow internal design minimizes adhesive stagnation and char buildup, helping reduce nozzle plugging and unplanned downtime.
• Integrated Filtration for Cleaner Performance: Heated manifold filtration and module-level filters capture debris and char before reaching critical sealing components, supporting consistent bead quality and longer service intervals.
• Accurate Temperature Feedback with Pt 100 RTD: Equipped with a Pt 100 RTD to provide precise temperature monitoring during continuous operation, supporting stable adhesive performance in high-speed packaging environments.
