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; 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 ℃; 3, temperature set value deviation protection to avoid misoperation; *4, standard with thermal printer, you can real-time or regular print temperature data; *5, ** refrigeration layout, the temperature inside the box is stable within 4 ± 2 ℃; 6, temperature-sensitive box design, simulated display of the real temperature of the sample, to provide reagents and drugs required for a stable storage environment. Refrigeration system: *1, international famous brand compressor, non-fluorine environmentally friendly high-efficiency refrigerant, fast refrigeration, high refrigeration efficiency, low power consumption; *2, copper tube aluminum fin evaporator with back-blowing 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 72 hours), open and close the door abnormal alarm function; *2, with sound beeping and light flashing dual alarm mode; *3, thermostat measuring point dual display dual control operation mode; *4, password protection function, placed arbitrarily adjust the operating parameters; *5, power failure protection: delayed start function, to avoid the power grid to restore power supply when multiple devices start at the same time resulting in circuit breaker protection.
