Metal Structured Performated Tower Packing
Structured Packing is a kind of packing arranged and stacked in accordance with uiform geometry in the tower.The geometry of the whole tower section is regular,symmetrical and uniform, and the gas-liquid flow path is specified ,which reduces the phenomeneon of channel flow and wall flow, and the pressure drop can be very small.Under the same energy cost and pressure drop, it can provide more specific suface area than random packing, and achieve higher mass transfer and heat transfer efficiency in the same volume. In recent decades, structured packing has been widely used in many towers in fine chemical industry,perfume industry,oil refining,fertilizer,petrochemical industry and the other fields. Structured packings are available in two different inclination angles,ie. Type X and Type Y. The type Y packings have an inclination and angle of about 45 from the horizontal axis, and are the most widely used.The type X packings have an inclination angle of 30 from horizontal axis and are used in high capacity and low pressure drop applications.

The main function of these devices is to support the tower packing bed structurally. Support grids work in both structured and random packing processes for a wide range of purposes.  
plastic bubble cap tray
Plastic Bubble Cap For Chemical Industry
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.

bio ball filter
Plastic Bio Ball Packing for Water Treatment
It was invented by Jaeger Tri. Generally speaking, No big surface area is Tri-pack's biggest advantage. The distinctive shaping of ribs, struts and drip rods gives Tri-Packs tower packing media superior wetting characteristics, and the ability to maintain uniform liquid distribution throughout the bed. In the traditional theory of mass transfer, we often think big surface area will increase the mass transfer efficiency. Sometimes, Excess surface area can impede gas/liquid contact and create higher pressure drops,. Finally, it will lead to Packing's channel blocking.Based on this new understanding, Jaeger had invented Tri-pack.  Basically this pack provides maximum surface contract between the gas and the scrubbing liquid by facilitation through continuous formation of droplets by the packed bed. It was recognized best packing in for air stripping,degasifier and scrubber    
MBBR packing for water treatment
Plastic MBBR for Water Treatment
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

    Our Labor Day departmental competitions
    In the application competition, Liu Yun used two hardcore AI applications - capacity calculator development and plastic bulk packing market data analysis, demonstrating the innovative power of deep integration of technology and business, and installing an "intelligent engine" for production decision-making! Traditional capacity accounting relies on Excel formulas, which have complex logic and difficult debugging. Manual verification is prone to errors and time-consuming. Liu Yun boldly made a breakthrough, from Excel to intelligent programs, enabling complex calculations to be easily solved with just one click. This has enabled the use of AI tools to reconstruct a new process for capacity calculation. Liu Yun's exploration is not just about tool application, but also focuses on building a comprehensive closed-loop system of data collection, intelligent analysis, and production feedback. The beauty of labor lies in using wisdom to solve difficult problems; The light of struggle lies in leading the future with innovation! Liu Yun uses AI as a pen to outline an efficient and accurate picture on the canvas of production and market, which is a vivid portrayal of the mass transfer industry's "good use of tools and meticulous cultivation" in the new era. In the past, collecting mileage data from 2891 counties and districts across the country required manual search and individual input into Excel, which took a full 15 days. The data was chaotic and prone to errors. Liu Liping innovatively combines ChatGPT with custom crawler scripts to turn AI into a "data special forces soldier". Writing a logistics analysis report used to be a worrying "time-consuming project" that could not be completed. Format adjustment, data collection, and text polishing take an average of 4 hours and are often reworked due to human errors. Liu Liping used NotionAI and Wen Xin to combine a single word with a sword, ushering in a "second level era" for report generation. The beauty of labor lies in innovation and breakthroughs; The light of struggle illuminates the future of efficiency! Liu Liping's use of AI technology to rewrite the logistics data processing mode, making "efficiency, precision, and intelligence" the new normal of work, is the best portrayal of the "good use of tools and daring to innovate" of the new era's IT personnel!

    The spring team building activity of Jiangxi Ayrtter 2025 has come to a successful conclusion!
    On April 17, 2025, more than 40 emplyee from Jiangxi Ayrtter Mass Transfer Technology Co., Ltd. gathered at the foot of Wugong Mountain. Embarking on a 14 hour extreme challenge - from "blindfolded collaboration" to "desert survival", from "barefoot walking on fire" to "starry night talk", this spring team building themed "infinite communication, collaborative win-win" is not only a game of physical fitness and intelligence, but also a team melting that strikes the soul. The team strengthened their understanding through challenges and gathered strength through laughter.         With the instructor's command, this expansion training began. The training activities are divided into six projects, namely "Ice Breaking Action, Joint Bridge Building, Blind Formation, Rapid 60 Seconds, Desert Survival, and Fire Release Conference". The challenges are impossible, and each project contains deep meanings of establishing team awareness, strengthening communication and cooperation, and exercising leadership skills.   As night falls, the highlight of the event, the "Fire Out Ceremony," ignites the entire audience. Standing on the scorching 600 ℃ charcoal fire with bare feet, some held their breath and focused, while others cheered and cheered. When everyone successfully crossed the path of fire, the cheers shook the valley! This is not magic, but a dual victory of psychology and team energy - as the participants said, "Fear is never the flame, but the boundaries of one's own heart." The Ayrtter employee broke through their limits with actions and stepped out of the new power of team beliefs.     When the bonfire illuminates the night sky of Wugong Mountain, the aroma of barbecue interweaves with laughter and joy, and the tense nerves are completely relaxed at this moment. Colleagues gathered around the stove to chat and share their day's insights.
