Metal VSP Ring
Metal VSP Ring(Very special packing), commonly known as Mella ring in the world, is one kind of metal packing like a floral hoop, belongs to series products different in size. It is characterized in larger annual wall open area, large flux, small resistance and high mass transfer efficiency
Metal VSP inner arc ring (Very special packing) means very good packing, also known as Mallar ring packing. The VSP inner arc ring packing has reasonable geometric symmetry, good structural uniformity and high porosity. The packing surface is continuous but not broken, and is evenly distributed in space. Compared with the Pall ring, the flux can be increased by 15-30%, and the pressure drop can be reduced by 20-30%.
The characteristic of the VSP inner arc ring is that the open area of the ring wall is large, so it has the characteristics of large flux, low resistance and high mass transfer efficiency.
