  • Quiet operation
  • Accumulates a wide variety of product sizes
  • No minimum weight limitations
  • Each zone features positive braking of each roller in the zone during accumulation
  • Product may be released in singulation or slug fashion
  • Smart Zone™ eliminates sensor rollers and replaces with photoelectric sensors to accumulate products with previously difficult minimal weight restrictions
  • Curves, spurs and other modules may be driven by a single drive
  • Fully customizable
