ITW Simplicity Adhesive Supply Unit

The SimplicityTM ASU takes innovation, technology and performance to the next level. Clear, intuitive V6 controls and a modular design make it simple to install, operate and maintain. With a distinctive new orange ceramic coating, this compact unit features an HMI and hopper lid swivel for flexible configurations, while its small internal reservoir and auto-feeding system rivals “tankless” systems. To match the production needs optimally, at the 16 kg hopper (only) a pre-melt grid can be mounted to increase the adhesive melt rate and two piston pumps can be mounted to double the delivery rate, which make SimplicityTM unique and exceptional in his class.


  • “Turn it on and walk away” convenience makes it an outstanding value
  • Vertically integrated pump with easy-spin pump filter
  • Easy-to-operate single board control eliminates the need for extensive training
  • Melt-On-Demand technology eliminates charring and reduces maintenance
  • Dual piston pump capabilities (16 kg unit only)
  • All-in-one filter/regulator with integrated pre-filter and coalescing filter


  • 4 kg, 8 kg, 16 kg tank sizes
  • 400 VAC or 480 VAC w/o neutral transformers
  • Low-Level sensor
  • Pre-filter gauges cue filter change or clogged nozzles
  • Dynafill auto feed capable
  • Accommodates as many as six hoses
  • Available pre-melt grid for increased melt rate

ITW Simplicity


Adhesive degradation is recognized as the number one cause of downtime on hot melt equipment. To address this problem, ITW Dynatec has patented a “Melt‑On‑Demand” system. ITW Dynatec’s vertical, unheated hoppers only melt the amount of adhesive required by the application. Most of the hot melt adhesive in the hopper remains at a much lower temperature, perhaps even solid state. The added benefits of melting only the adhesive required are quicker start-ups, reduced energy costs, better viscosity control, and reduced fumes.
