Graco 25B021 InvisiPac GM100 Single Slim Hot Melt Applicator with 24 VDC Solenoid and Pt 100 RTD

Graco GM100 InvisiPac Single Slim High-Speed Adhesive Dispenser for Box and Carton Sealing

Built for precise adhesive dispensing, the Graco 25B021 InvisiPac GM100 is a single slim, plug-free hot melt applicator engineered for high-speed box and carton sealing applications where precision and uptime are critical. Designed as an InvisiPac applicator, this adhesive dispenser delivers fast, accurate dot and stitch placement while eliminating nozzle plugging and reducing adhesive char, helping minimize downtime in continuous production environments. Its compact form factor allows easy integration into tight packaging machinery without sacrificing performance.

Used with the Graco InvisiPac Tank-Free Hot Melt Delivery System, the GM100 is fully compatible with HM10, HM25c, and HM50 systems, ensuring consistent adhesive flow and cleaner operation across the entire dispensing system. The applicator features a 24 VDC solenoid valve for reliable high-speed cycling and a Pt 100 RTD for precise temperature monitoring. With a slim single-module design and a heat-up time of under 10 minutes, the GM100 supports continuous operation in demanding manufacturing adhesive systems and dispense-valve applications.

Additional InvisiPac GM100 applicator configurations are available.

Graco 25B021 Advantages in InvisiPac Tank-Free Adhesive Systems

• Heat-Up Characteristics: Reaches operating temperature in approximately 10 minutes, allowing production lines to return to operation quickly after startup or planned downtime.
• Single Slim Applicator Design: Configured with one adhesive module in a slim housing to support installation in tight machine geometries commonly found in high-speed packaging equipment.
• Electrical Components: Uses a 24 VDC solenoid valve and a Pt 100 RTD to provide reliable actuation and accurate temperature sensing during continuous operation.
• Pneumatic Mode of Operation: Operates using air-opened, air-closed actuation to control adhesive dispensing at speeds exceeding 10,000 cycles per minute.
• Plug-Free Adhesive Flow: The InvisiPac™ free-flow manifold and integrated filtering eliminate dead zones where adhesive char can form, reducing nozzle plugging and maintenance requirements.
• Application Use: Functions as an InvisiPac applicator and dispense valve for precise dot and stitch placement in box and carton sealing applications.
