Graco 24U023 InvisiPac GS35 Single Slim Hot Melt Applicator with No Solenoid and Pt 100 RTD

InvisiPac GS35 Single Slim Hot Melt Applicator for Glue Melter Systems

The Graco 24U023 InvisiPac GS35 is a single slim hot melt applicator configured without an onboard solenoid, intended for constant bead adhesive dispensing in case and carton sealing applications. The slim, space-saving design allows integration into tight machine layouts while maintaining stable, uninterrupted adhesive flow. Its plug-free construction helps eliminate nozzle plugging and reduce adhesive char, supporting improved uptime and clean operation in continuous packaging environments.

The applicator incorporates a Pt 100 RTD for accurate temperature monitoring and reaches operating temperature in under 10 minutes, allowing production lines to start quickly. Operating in an air-opened, spring-closed configuration with cycle speeds up to 3,500 cycles per minute, this single-module GS35 is well suited for high-speed packaging lines that demand consistent bead control and minimal maintenance. When used 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 model is part of the InvisiPac GS35 applicator series. View all available GS35 configurations here.

Graco GS35 24U023 Benefits for Industrial Packaging Equipment

• Slim, Space-Efficient Applicator Design: Single slim body installs easily in tight machine layouts, making it well suited for compact packaging and sealing equipment.
• External Actuation Ready (No Solenoid): Configured without an onboard solenoid for systems that use centralized or remote valve actuation, allowing flexible integration into existing InvisiPac setups.
• Consistent Constant-Bead Output: Designed specifically for steady, uninterrupted bead dispensing in case and carton sealing applications where uniform adhesive flow is required.
• Char-Reducing Manifold and Filtration System: Free-flow adhesive routing with integrated applicator and module filtering helps limit char formation and reduce the risk of nozzle blockage.
• Air-Opened, Spring-Closed Valve Operation: Pneumatic design provides reliable bead shutoff and repeatable adhesive control at operating speeds up to 3,500 cycles per minute.
• Quick Start Heat-Up Capability: Reaches operating temperature in under 10 minutes, helping packaging lines return to production faster after startups or maintenance events.
