Adhesive is processed in a better way

  • The applicator’s free-flow manifold design is engineered to eliminate dead zones where char will build up
  • Module includes an integrated filter assembly near the ball and seat junction that eliminates nozzle plugging
  • Adhesive spends less time at high temperature, resulting in less char
  • Changes in the heated hose construction significantly reduce the formation of char in the hose itself
  • Less char allows you to use lower cost adhesives and save money
  • Works with the InvisiPac Tank-Free Hot Melt Delivery System
  • Quick start-up – ready in less than 10 minutes
  • Tank-Free design means adhesive spends less time at high temperatures – significantly reducing char
  • Less char results in less nozzle plugging, less system maintenance and more uptime
