Ceramic surface can generate extremely thin liquid film. Turbulent liquid flow and tortuous vapor flow passages promote mixing of liquid and vapor with low pressure drop. These are reasons that our ceramic structured packings have the same mass transfer efficiency as metal packings. Meanwhile, they are much more resistant to corrosion and high temperature than metal packings.  

Since Metal Mellapak was be developed & accepted by market. Scientists find Metal Corrugated plate packing was not suitable in any medium’ s requirement  (acid). Furthermore, it is very hard to widely used in industry field. After that, Plastic Corrugated plate packing was born. Compared with Metal Corrugated plate packing, it has large flux, low pressure drop,large surface area and so on.  

Bubble cap tray is a flat perforated plate with risers (like pipes) around the perforations, and caps in the form of inverted cups over the risers.The caps are usually equipped with slots or holes through which vapor comes out. The cap is mounted so that there is a space between riser and cap to allow the passage of vapor. Vapor rises through the riser and is directed downward by the cap passing through slots in the cap, and finally bubbling through the liquid on the tray. As vapor has to pass through many passages this lead to higher pressure drop and lower capacity than other conventional trays. Liquid and froth are filled on the tray to a depth at least equal to the weir height or riser height, giving the bubble-cap tray a unique ability to be used for reaction applications.      

Jet ring products are mainly based on pall ring packing by mold processing improvement. It extends to the rib in the ring, which makes the window form two open cones with opposite directions. Because the cone guides the liquid flow and the air flow to gather and disperse in the ring, it produces strong disturbance.  

Copper Intalox saddle rings combine the benefits of Intalox saddle ring packing with the properties of copper.    Characteristics Material: Made from copper, which offers excellent thermal and electrical conductivity. Shape: The saddle shape allows for efficient packing and maximizes surface area for gas-liquid interactions. Corrosion Resistance: Copper provides good resistance to certain chemicals, making it suitable for specific environments.

It was invented by German BASF, the first generation  Random packing. To compared with Raschig ring, the most important improvement is increase two row of  inward ligule. It promotes liquid-gas liquidity and improve tower’ s packing’ s mass transfer performance.  

It is a type of wastewater treatment process that was first invented by Prof.Hallvard  Degaard at University of Science and Technology in the lates of 1980s.The MBBR system consists of an aeration tank (similar to a activated sludge tank) with special plastic carriers that provide a surface where a biofilm can grow. The carriers are made of a material with a density close to the density of water (1 g/cm3). An example is high-density polyethylene (HDPE) which has a density close to 0.95 g/cm3. The carriers will be mixed in the tank by the aeration system and thus will have good contact between the substrate in the influent wastewater and the biomass on the carriers    

Owing to this pack’ s shape is like saddle, so called saddle ring or Berl Ring. The earliest saddle ring’ s material is ceramic. In our actual application, when gas flows upward, liquid will flow downward along with arc channel. This Movement way will directly reduce wall flow’ s happening. However, Arched external frame also cause overlapping & bridging . Therefore, scientists change two ends into rectangle type contact surface. This improvement will reduce bridging’ happen.  

Plastic tri-pack ring is a type of random tower packing, which has hollow, spherical structure. Plastic tri- pack has a symmetrical geometry, which is made from a unique network of ribs, struts and drip rods. It is made of injection molded plastic, including PP, PE, PVC, PVDF and other materials.  

Plastic polyhedral hollow ball also called multiaspect hollow ball. It is a new type of high efficient random packing. It is made from heat resistant and chemical stable plastic material. It is composed of two hemispheres to form a whole ball shape. Each hemisphere surface has several half fan-shape leaves, the upper and lower leaves are staggered arranged. This design makes the polyhedral hollow ball lighter weight, smaller wind and flowing resistance and good hydrophilic surface.  

VSP ring also called inner arc ring. VSP rings have reasonable geometric symmetry, which the inner arc are folded evenly along the axial direction and replaced alternated arranged.Its structure is very similar to the Nor Pak. It is a ideal replacement of gas & liquid scrubbing.

Metal tellerette ring packing is made of sheet metal stamping, stretching into specific calender, mesh surface into the rules of the diamond mesh, wire mesh corrugated packing geometric rules. Garland filler available various materials processing, material selection of a wire mesh packing is wide, and corrosion resistant performance is good.Garland filler has a wreath of plastic packing and garland filler metal.The wreath of plastic packing appear earlier, and more for gas washing, purification tower.Metal Tellerette Packing like ellipse is made of many enlaced cirques. Due to its high liquid storage in lacuna of packing, it prolongs time of gas-liquid contact, enhance the efficiency of transfer, It has the characteristic of big voidage, low pressure drop, sufficiency gas-liquid contact,low weight.
