r Ultra-low temperature refrigerator warranty common sense:
Ultra-low temperature refrigerator maintenance and Maintenance is particularly important to prolong its life and normal use. Inaccurate temperature control often results in damage to the stored objects, which has a great impact on the experimental results and thus affects the normal progress of research work.
． Clean once a month to ensure its cleanliness
Use a dry cloth to remove a small amount of dust on the inside, outside and accessories of the refrigerator. If the refrigerator is too dirty, use a neutral detergent. After cleaning, rinse thoroughly with pure water. However, do not flush the inside or upper part of the refrigerator, otherwise it will damage the insulation material and cause malfunction. The compressor and other mechanical parts do not require the use of lubricating oil. Be careful when cleaning the fan behind the compressor. After cleaning, perform a safety check to ensure that the plug of the refrigerator is plugged in properly and not empty. Make sure that the plug does not become abnormally hot. Make sure that the power cord and distribution cord on the back of the refrigerator are not cracked or scored.
． Siren starts alarm
When encountering siren starts alarm, you can usually check through the following aspects.
First, check whether there is a problem with the power supply or whether the plug has been pulled out of the socket
Second, check whether the internal thermometer is out of the appropriate range. In this case, placing objects will cause the refrigerator to heat up and trigger Alarm
Third, check whether too many items are placed at one time.
． Insufficient cooling of the refrigerator
Check whether there is frost on the surface of the evaporator. Whether the refrigerator door opens and closes too frequently. Whether the back of the refrigerator is in contact with the wall and whether there are too many items placed there.
． The refrigerator makes too much noise
Check whether the base plate is strong and the refrigerator is stable. If not, adjust the movable screws so that the four corners are firmly supported on the base plate. Check whether there are any objects touching the back of the refrigerator.
If the cooling effect is poor, the refrigerator does not stop, the heat pipe is not hot, and the evaporator makes a small air flow sound, these are caused by slow leakage causing serious refrigerant defects. In the actual use process, many other problems will be encountered. The solutions to such problems require continuous accumulation of experience to eliminate obstacles and make the ultra-low temperature refrigerator reach the best working condition.

． After installing the remote alarm system, you can enter the mobile phone number of our engineer, so that we can detect machine faults as soon as possible and arrange for engineers to solve the fault as quickly as possible. Company history: Our company was established in 2000. During the development process of 2008, three engineers have been committed to the research and practice of ultra-low temperature. At first, we only focused on ultra-low temperature refrigerators. At that time, there were few low-temperature refrigerators, and foreign after-sales work could not keep up. , there are very few domestic maintenance companies. We established the low-temperature refrigeration technical service company based on the current situation, which is relatively early in the country. We have cooperated with many teaching and scientific research institutions in Shanghai on the maintenance of low-temperature refrigerators, and cooperated with the American and Japanese sales companies in Beijing. The company cooperates with the company as their after-sales service company, so Injured Sheep has 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 low-temperature centrifuges, freeze dryers, cold wells, etc. Many, mastering the degree of refrigerants and technologies, all low-temperature equipment technologies are similar. It is not only limited to the maintenance technology of the above three well-known brands of refrigerators, but also knows a few such as: and domestic brands. The scope of maintenance is not limited to Shanghai. region, but also nationwide. 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. 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.
After receiving the repair call, the company immediately prepared a service vehicle and rushed to the scene wearing all the accessories of the machine (compressor refrigerant circuit accessories) and tools. Repair the machine as quickly as possible. Maintenance in other places can be done through the Internet, and local engineers can be guided through video repairs, so that we can accurately determine the fault, solve it ourselves if we can, and avoid shortage of accessories after we arrive at the scene.

Level indicates that the product has reached the international advanced level and is the most energy-saving< br/> Level indicates relatively energy-saving
Level indicates that the energy efficiency of the product is the average level of the market
Level indicates that the energy efficiency of the product is lower than the market average level
Level indicates high energy consumption and is the market standard. Input indicators, products below this level are not allowed to be produced.
r Ultra-low temperature refrigerator maintenance:
r Ultra-low temperature refrigerator equipment has high maintenance costs due to the scarcity of refrigeration working fluids, high prices, complex equipment structures, and high maintenance costs. Ultra-low temperature refrigerators are frequently damaged, mostly due to improper use and maintenance. Summer is coming and equipment failures are high. In order to ensure the normal operation of ultra-low temperature refrigerators and prevent equipment damage, it is recommended to pay attention to the following points:
Ensure the ambient temperature. The working environment temperature of the ultra-low temperature refrigerator must be below &C, and the surrounding area must be well ventilated. Excessive temperature or poor ventilation can easily cause equipment to be overloaded and damaged.
Clean the cooling filter regularly (once every two months). If the filter is not cleaned for a long time, dust will clog the mesh, resulting in poor heat dissipation, damage to the cooling motor, and then damage to the compressor. Please refer to the instruction manual for cleaning instructions.
Regularly clean the ice on the refrigerator door seal. If the door seal is not tight, the thermal insulation effect will be seriously reduced, which may easily cause damage to the compressor due to long-term overload operation.
