Ultra-low temperature refrigerator product features:
Usage: It can be used for scientific research, low-temperature experiments on special materials, cryopreservation of red blood cells, white blood cells, skin, bones, bacteria, [banned words], biological products, and ocean-going products , electronic devices, low-temperature experiments on special materials, etc. Suitable for blood stations, hospitals, health and epidemic prevention systems, scientific research institutes, electronics industry, chemical industry, bioengineering, university laboratories, military industry enterprises, ocean fishing companies, etc.
Cutting-edge refrigeration technology: The "Zhonghuahao" completely environmentally friendly refrigeration fluid invented by the Institute of Physics and Chemistry of the Chinese Academy of Sciences is used. The result has passed the national appraisal composed of five famous academicians. (Chinese invention patent number: .) Adopts unique refrigeration circuit and single-stage oil lubricated compressor refrigeration technology with China's independent intellectual property rights (Chinese invention patent number: ., .) Adopts unique secondary foaming technology and multi-channel door seal design
Effectively prevent low-temperature damage to the insulation layer and achieve world-leading insulation effect using fluorine-free environmentally friendly refrigerant, international famous brand high-efficiency compressor, energy-saving and silent German B fan motor without polyurethane foam, ultra-thick insulation layer, insulation board , good thermal insulation effect.
Cutting-edge control technology: microcomputer temperature control system, platinum resistance temperature sensor box temperature can be freely set within the range of ℃ ~ ℃ digital temperature display, keep track of the operating status at any time, optional temperature recording printer function, backup battery, alarm Lamp, voltage compensation, remote centralized control system.
Humanized design: Rotate the power-assisted handle for easy opening (horizontal version is a balanced hinge for the door body). Adjustable shelf structure for easy storage of items (vertical version only). Internal and external double-layer door design locks in air conditioning and improves thermal insulation. Good (vertical only).
Security system: keyboard lock and password protection functions to prevent arbitrary adjustment of operating parameters such as startup delay, shutdown interval and other protection functions to ensure reliable operation and perfect sound and light alarm system (sensor failure, high and low temperature, low battery, door opening, etc.) Filter blockage, system failure, etc.), items are stored more safely and the door body is equipped with a lock to prevent random opening of the door.
Ultra-low temperature refrigerator maintenance tips
When the alarm starts to sound, 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
br/> Second, check whether the internal thermometer is outside the appropriate range. In this case, placing items will heat up the refrigerator and trigger the alarm. Third, check whether too many items are placed at once.
.When the refrigerator is not cooled sufficiently:
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 too many items are placed there.
. When 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 damage to the refrigerant. 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.
. 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, use pure Rinse thoroughly with 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.
