DYNAC 6900

FIFO accumulation in a circular footprint for high-speed lines.


The Model 6900 is a high-speed single-file DYNAC FIFO accumulation and buffering conveyor that responds dynamically to the conditions of the line. It provides pressure-less product handling, as well as unique line balancing characteristics for a variety of rigid and flexible container types. The 6900’s circular spiral configuration enables the implementation of Hartness’ industry-leading, DYNAC-centric line concept, which eliminates complicated controls and allows for close coupling of machine centers. This close coupling leads to a smaller line footprint that requires fewer operators and less consumption of utilities than traditional line designs. The 6900 is exceptionally versatile, handling a wide range of product and packaging shapes, sizes, formats, weights, and materials.
