Specifications

Metal tower packing is made of materials like carbon steel, stainless steel or Aluminum alloy, etc. The product has features such as thin wall, heat resistant, high void ratio, high capacity, low resistance, high separation efficiency and so on. It is especially suitable for rectification towers under vacuum to treat thermosensitive, decomposable, polymerizable or cokable systems, so it is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc.
