Graco 24U028 InvisiPac GS35 Low-Profile Dual Hot Melt Applicator with 110 VAC Solenoid and Pt 100 RTD

InvisiPac 24U028 GS35 Low-Profile Dual Hot Melt Adhesive Applicator by Graco

Designed for constant bead adhesive dispensing in space-restricted packaging machinery, the Graco 24U028 InvisiPac GS35 low-profile dual hot melt applicator provides stable, uniform adhesive output across two dispense points while maintaining a compact vertical footprint. The low-profile dual configuration supports consistent bead formation in high-speed case and carton sealing operations, making it well suited for packaging lines where clearance is limited but performance cannot be compromised. Built with a plug-free adhesive path, the GS35 minimizes nozzle plugging and adhesive char, helping maintain cleaner operation and reduce maintenance interruptions in continuous production environments.

When integrated with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 enables clean, efficient adhesive delivery across the entire dispensing system. This configuration is equipped with a 110 VAC solenoid valve for dependable actuation and a Pt 100 RTD to provide accurate temperature monitoring during 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 24U028 functions as a reliable adhesive dispenser and dispense valve solution for industrial packaging equipment and constant bead box sealing applications.
