Graco 24U027 InvisiPac GS35 Low-Profile Dual Hot Melt Applicator with 24 VDC Solenoid and Pt 100 RTD

InvisiPac GS35 Low-Profile Dual Hot Melt Applicator for Glue Melter Systems

Designed for space-constrained packaging equipment, the Graco 24U027 InvisiPac GS35 low-profile dual hot melt applicator delivers reliable constant bead adhesive dispensing for high-speed case and carton sealing operations. The low-profile dual-module layout supports precise, uniform adhesive output while the plug-free design minimizes nozzle plugging and adhesive char, helping reduce downtime in continuous production environments. Built as part of the Graco InvisiPac platform, the GS35 is designed for use with the Graco InvisiPac Tank-Free Hot Melt Delivery System to support clean, efficient adhesive dispensing across packaging lines.

Performance and uptime are further supported by the GS35’s fast heat-up and filtration design. The applicator reaches operating temperature in under 10 minutes and uses a free-flow manifold with heated-zone filtration to eliminate cold spots and dead zones where char can form. An integrated module filter protects the ball and seat from debris, enabling stable operation at cycle speeds up to 3,500 cycles per minute. Equipped with a 24 VDC solenoid valve and Pt 100 RTD, the GS35 provides accurate temperature control and dependable performance in demanding packaging environments.

Key Features and Operating Benefits of InvisiPac 24U027 Valve

• Built for Continuous Case and Carton Sealing: Designed specifically for constant bead applications, this dual-module GS35 delivers steady, uninterrupted adhesive flow in high-speed packaging operations.
• Clean Adhesive Delivery with Less Maintenance: A free-flow manifold and heated-zone filtration reduce adhesive char and debris buildup, helping prevent nozzle plugging and keeping maintenance intervals longer.
• Reliable Temperature Control and Actuation: The applicator uses a 24 VDC solenoid valve for responsive operation and a Pt 100 RTD to maintain accurate temperature monitoring during continuous production.
• Fast Heat-Up for Quicker Line Restarts: Reaches operating temperature in under 10 minutes, reducing downtime after changeovers, maintenance, or system startup.
• Low-Profile Design for Tight Machine Layouts: The reduced-height dual configuration fits easily into space-constrained packaging equipment without sacrificing dispensing performance.
• Stable Operation at Production Speeds: Operates in an air-open, spring-close configuration at speeds up to 3,500 cycles per minute, supporting consistent bead quality in demanding manufacturing environments.
