Medical blood refrigerator is mainly used to store whole blood, red blood cells, biological products, vaccines, special reagents and so on. It is widely used in blood stations, hospitals, disease prevention and control centers, animal husbandry, scientific research institutions, electronics, chemical industry and other industries. Structure design: *1, the box shell is made of high-quality cold-rolled steel plate, after environmental protection, amalgamation, spraying and other processes, strong corrosion resistance; *2, the inner box adopts SUS304 stainless steel plate; *3, foam door body, better heat preservation; Temperature control: 1, the use of microcomputer control system, temperature digital display, to ensure ** stable operation; *2, accurate electronic temperature control, accuracy of 0.1 ℃, temperature-sensitive box design, analog display of the blood bag inside really real temperature; 3、Temperature set value deviation protection to avoid misuse; *4, standard with thermal printer, you can print real-time or regular temperature data; *5, cold air back-blowing design, the temperature inside the box is stabilized within the range of 4 ± 2 ℃; 6、Reliable temperature control to provide the required storage environment for reagents, drugs and samples. Refrigeration system: *1, international famous brand compressor, non-fluorine environmentally friendly high-efficiency refrigerant, fast refrigeration speed, high refrigeration efficiency, low power consumption; *2, copper tube aluminum fin evaporator with a unique circulating air cooling system design, to ensure that the internal temperature of the refrigerator is constant; *3, high-density thermal insulation foam layer using polyurethane cyclopentane foam, good thermal insulation effect. Safety guarantee: *1, with the box high and low temperature alarm, sensor failure alarm, power failure alarm (support for 72 hours), switching door abnormal alarm function; with sound beeping and light flashing dual alarm mode; *2, thermostat measuring point dual display dual control operation mode; *3, password protection function, to prevent arbitrary adjustment of operating parameters; *4, power failure protection: refrigerator delay start function, to avoid the power grid to restore power supply when multiple devices start at the same time resulting in circuit breaker protection.
