& Service hotline: Maintenance hotline: Contact person: Mr. Wang
Shanghai Zhongke Meiling ultra-low temperature refrigerator after-sales maintenance company was established in 2008. During the development process of 2018, three engineers have been committed to the research and practice of ultra-low temperature. At first, we only focused on ultra-low temperature refrigerators. There were few low-temperature refrigerators at that time, and foreign after-sales work could not keep up. There were only a few domestic maintenance companies. We originally established a low-temperature refrigeration technology service company based on the current situation. This was relatively early in China. We cooperate with many teaching and scientific research institutions in Shanghai on the maintenance of low-temperature refrigerators, and cooperate with the sales company of American and Japanese Zhongke Meiling in Shanghai as their after-sales service company, so we have accumulated a lot of technical experience. Now, as an ultra-low temperature technical service company, we are not only limited to the repair of ultra-low temperature refrigerators, but also repair a lot of low-temperature centrifuges, freeze dryers, cold wells, etc. We have mastered the most advanced refrigerants and technologies. All low-temperature equipment technologies are similar. The repair technology is not only limited to the above three well-known brands of refrigerators, but also knows a few domestic brands such as: The repair scope is not only limited to Shanghai, but also covers the whole country. The three northeastern provinces, including Inner Mongolia, Xi'an, Henan, Guangzhou and Shenzhen, all have the exquisite skills and hard work of our engineers displayed. Quickly and skillfully solve problems for customers, winning their praise. In terms of accessories, because foreign manufacturers do not allow unreasonable import of accessories (for fear of us saving machines), after the machine is damaged, the old machine must be replaced with a new one. Therefore, we found scrapped machines through various channels and exchanged them for many new machines, so we have spare parts Sufficient, generally not used for three months. The refrigerant types are complete and sufficient, including R and so on. As for tools, we use professional repair tools. The combined fluoride pipe imported from the United States alone is worth more than 2,000 yuan. Only high-quality tools can match superb technology. Our mission: bring you trust, earnestly fulfill every promise to bring you quality, fully ensure that every link brings you benefits, carefully calculate every choice to bring you convenience, and meticulously improve every service. Once you cooperate, you will benefit for life. , a professional ultra-low temperature refrigerator repair service center, your wise choice! ! !

According to our many years of maintenance experience, the reasons for the failure of most low-temperature refrigerators are:
Condenser power box, compressor working area, dirty fan, lack of oil, large working current, compressor fan is easy to burn out, and the whole machine vibrates violently System pipes are prone to collision and friction, causing refrigerant leakage. Therefore, regular cleaning and maintenance are the first priority, as well as professional measurements of the components in the power box. As long as this is done strictly, the failure rate of all low-temperature refrigerators will be greatly reduced.
If the customer entrusts our professional company to perform maintenance, after the contract is signed, we will strictly follow the above procedures and perform maintenance procedures at least six times a year.
