The conference released the brand-new service policy of Zhongke Meiling in 2024, which will improve the service quality, improve the service quality, accelerate the development of new quality productivity, and make "Made in China" give users a better experience!
As a leading enterprise specializing in the field of low-temperature technology, Zhongke Meiling has always adhered to the strategy of technological innovation as the driving force, product upgrading as the starting point and global layout, providing customers with more efficient, stable and safe low-temperature technology products, and constantly pushing enterprise services to a new level.
Technological innovation and breakthrough: leading the world and creating records
Looking back on the 22-year pioneering course, Zhongke Meiling has made many scientific and technological innovations and breakthroughs in the field of ultra-low temperature storage.
In 2002, relying on the auto-cascade refrigeration technology initiated by the Institute of Physics and Chemistry of Chinese Academy of Sciences, Zhongke Meiling developed a series of ultra-low temperature refrigerated storage boxes with independent intellectual property rights, which were suitable for pharmaceutical, hospital, scientific research and other scenarios, making China’s life science research bid farewell to the era of long-term dependence on imported ultra-low temperature products.
It is worth mentioning that in December 2006, DW-ZW128 at -164℃ created by Zhongke Meiling became the world record for the lowest storage temperature of compressor refrigeration in the world, marking the first time that China’s ultra-low temperature storage refrigeration technology surpassed the United States and Japan to lead the world.
In addition, on the basis of Zhonghua No.1 refrigeration technology, Zhongke Meiling made many breakthroughs and successfully developed Zhonghua No.9 refrigeration technology. Compared with the previous compressor, the new technology reduces the exhaust pressure by 20%, the exhaust temperature by 21%, the system stability is greatly improved, and the cooling limit of the new technology is reduced by 16℃, reaching the lowest refrigeration temperature of the compressor in the world of -180℃, setting a record again! Compared with double-machine cascade refrigeration technology, Zhonghua No.9 refrigeration technology reduces the system volume by one time. The frequency conversion dual-system ultra-low temperature products developed based on this technology can easily realize the design of independent dual refrigeration systems, and each system can independently drive the products to reach the set temperature, ensuring double safety. The two systems cooperate with each other in different modes, and can adjust different working modes such as energy saving mode, high performance mode and silent mode. Taking DW-HL680 as a representative, the energy consumption is reduced by 30%, the noise is reduced by 5dB, and the refrigeration efficiency is improved by 20%.
DW-TW128, also developed on the basis of Zhonghua No.9 technology, made a big debut with six core technologies, and made joint efforts from system pressure control, compressor temperature control, cold recovery cycle, heat preservation technology and intelligent control technology, reaching the lowest ultra-low temperature storage limit of electric refrigeration in the world: -180℃! Since then, electric refrigeration ultra-low temperature storage has entered the liquid nitrogen temperature zone, and the long-term storage of life samples no longer needs to rely on liquid nitrogen. In the face of every difficulty, the people of Zhongke Meiling are struggling to the end, striving for perfection and constantly subverting until they break the ice and open a new era of low-temperature storage!
Product iteration and upgrading: leading the development trend of the industry
In February 2016, Zhongke Meiling officially landed on the New Third Board, which opened the voyage stage. The company has developed a diversified development strategy based on biomedical field, and rapidly promoted the transformation of brand products from "end product manufacturer" to "product+service provider".
Under the guidance of the new strategic policy, Zhongke Meiling has developed the second-generation products that can create core values for customers, leading the development trend of ultra-low temperature storage industry.
The second-generation ultra-low temperature products are equipped with large-screen touch control system as standard, and the complex network+function. With its neat and elegant appearance, advanced performance and excellent quality, it has set off a product replacement storm in the ultra-low temperature storage industry. The second-generation refrigerator products all adopt air-cooled vortex circulating air duct and intelligent control system with 7 sensors, which has high temperature accuracy, low energy consumption, low noise and high platform design, leading the domestic refrigerator design trend. Advanced refrigeration technology and family industrial design not only enhance the market competitiveness of products, but also increase the brand recognition, which strongly promotes Zhongke Meiling to enter the fast lane of development.
In 2023, Zhongke Meiling released a brand-new technical crystallization-Ruilian medical refrigerator, adopting a brand-new frequency conversion air-cooled refrigerator technology platform, using pure carbon and hydrogen environmental protection refrigeration working medium, and the temperature uniformity is ≤ 1 C; Equipped with intelligent touch control system to realize visual traceability of data; With electromagnetic automatic door lock to support decentralized management function; Adopt high-strength antibacterial injection molding shelf, which is light, easy to clean and has strong bearing capacity. The medical refrigerator of Ruilian has completely subverted the industry’s cognition of the refrigerator from its face value to its performance.
Global vision and layout: research and development of diversified products
At present, in the face of ever-changing market changes, Zhongke Meiling has continuously introduced more products with core competitiveness. Zhongke Meiling knows that only with a global vision and a comprehensive strategic vision can enterprises be in an invincible position in the fierce market competition.
With the rapid development of molecular biology, the storage of biological samples has increased rapidly, and the scale of biological sample banks in various hospitals and scientific research institutions has expanded rapidly. With the scale of millions of samples and hundreds of ultra-low temperature refrigerator arrays, the access and management of samples have become the top priority of biological sample banks. Zhongke Meiling has laid out and developed a series of products, such as integrated biological sample bank, single biological sample bank and automatic liquid nitrogen biological sample bank, which can automatically access samples at ultra-low temperature on a large scale. Automatic sample library adopts modular design of functional units, physical partition design of storage units, multi-channel follow-up pipe picking technology and high-efficiency non-wet transfer window design, which has outstanding advantages in safety, customization, efficiency, practicality and convenience.
However, only low-temperature storage of end products can not meet the needs of domestic biomolecular research in basic equipment. Under the guidance of diversified development strategy based on biomedical field, Zhongke Meiling has launched a comprehensive strategic layout of products, and worked together from sample pretreatment, quality inspection, storage and cultivation to plan a series of products such as laboratory centrifuges, bio-safety cabinets and carbon dioxide incubators. At present, Ruigu series centrifuges and Ruijing series bio-safety cabinets have been mass-produced and listed.
The Ruigu series centrifuges newly developed by Zhongke Meiling are positioned as imported substitutes, and are benchmarked against internationally renowned brands. They adopt self-developed special technologies such as motor drive technology, rotor identification technology and centrifuge safety control technology, and have ultra-high speed precision control of 1 rpm, rapid cooling time of 4min and ultra-low running vibration of ≤0.003mm, which completely exceeds the technical performance and safety of imported products. Ruijing series bio-safety cabinets are designed with independent double fans, which can ensure the safety of personnel and environment in case of failure. The installation structure of quick-release filter is designed, which can easily replace the filter by only one person and shorten the time by 50%, greatly improving the convenience of use and further reducing the pollution risk when replacing the filter.
In the future, Zhongke Meiling will continue to adhere to the concept of "taking root with the accumulation and precipitation of technology, and growing up with high-quality products and services", work hard in the blue wisp of the road, forge ahead courageously through difficulties, drive service upgrade with scientific and technological innovation, and explore a new chapter in the future of products.
