Hiflow Ring is a 3rd generation high performance tower packing which provides an optimal design of high mechanical stability, void fraction and superior mass transfer performance.The grid structure guarantee its opening pore ratio exceeds 50% and Bed void fraction is higher than same size’s pall ring. Plastic hiflow Ring In addition, large fluid flux guarantee its pressure drop per square meter lower 45% than pall ring.Vertical bar staggered distribution and reinforced horizontal stripe largely improve its rigidity and strength.
