Graco 24U025 InvisiPac GS35 Single Slim Hot Melt Applicator with 110 VAC Solenoid and Ni 120 RTD

InvisiPac GS35 Single Slim Hot Melt Applicator for Glue Melter Systems

Graco 24U025 InvisiPac GS35 Single Slim Hot Melt Applicator is built for constant bead adhesive dispensing in space-constrained case and carton sealing equipment. Its plug-free design helps prevent nozzle plugging and reduce adhesive char, supporting stable bead formation and improved uptime in continuous packaging operations. The slim single-module profile allows the applicator to fit easily into compact machine layouts without sacrificing dispensing performance.

This GS35 model features an 110 VAC solenoid valve for dependable actuation and a Ni 120 RTD to provide accurate temperature feedback during operation. With a fast heat-up time of under 10 minutes and operating speeds up to 3,500 cycles per minute, it functions as a reliable hot melt dispenser and dispense valve for industrial packaging lines. At the system level, the applicator is designed for use with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, supporting clean adhesive delivery across the dispensing system.
