DYNAC 7100

Floor-level sequential accumulation and line control for high-speed lines


Mass Flow Pressure-less Accumulation

Hartness offers a variety of accumulation and buffering conveyors which we call DYNAC, designed to improve the throughput and efficiency of high-speed packaging lines. The DYNAC 7100 series are Hartness’ floor level, mass flow accumulation systems and come in three configurations:

  • 7100 –  the standard U-shaped configuration
  • 7100FT – in line flow through
  • 7100SF – with an integrated outfeed single filer

These mass flow DYNACs – a smart alternative to traditional bi-directional tables- provide FIFO accumulation, pressure-less product handling, as well as unique line balancing characteristics for glass, plastic and metal containers. The 7100’s space-saving configuration enables the implementation of Hartness’ industry-leading, DYNAC-centric line concept, which eliminates complicated controls and allows for close coupling of machine centers. The DYNAC 7100 automatically expands its usable length based on line conditions, eliminating the effects of slowdowns or micro-stops and ensuring a constant and optimal product flow between machine centers. DYNAC-centric lines have a smaller footprint and operate with minimal noise, even on glass.
