The Tank-Free™ system delivers hot melt material on demand for packaging bonding.

The in-line melter can produce 22 kg per hour and reaches operating temperature in 10 minutes – the fastest start-up time of any packaging line. "Melt-on-Demand" technology ensures a continuous adhesive flow. Less time at high temperature means more operating time and minimal maintenance-related downtime.

FIFO (First-in, first-out) ensures that the first adhesive is melted and dispensed first, eliminating adhesive charring and thermal shock. The integrated automatic vacuum feeding system saves labour costs by automatically drawing adhesive from a drum or bulk container.

The absence of contact with molten hot melt improves operator safety by reducing the risk of burns. The pattern control capability switches dispensing from a solid bead to a stitched bead at the push of a button, saving time and money. An optional signal light provides a visual indication of the system status.

The intuitive user interface monitors adhesive consumption and simplifies troubleshooting with usage data, error and event history downloadable via USB.
