    Wuxi Guanya Pharmaceutical Co.
    , Ltd.
    uses a compressor for mechanical refrigeration, and a circulating pump for cooling source transfer
    .

    The use of low-temperature liquids can be carried out by using double-layer glass reactors and rotary evaporators
    .

    The integrated pharmaceutical cooling and heating cycle machine can intelligently control the automatic opening of the refrigeration system, and the refrigeration system has multiple protection devices such as delay, overheating, and overcurrent
    .

    It is suitable for condensing water when low boiling point or heat-sensitive materials evaporate, which can not only save water but also ensure the rapid cooling of the cooled instrument.
    LEDs are used to display the temperature setting value and temperature measurement value
    .

    There are many kinds of refrigerants in the integrated pharmaceutical cooling and heating cycle machine.
    According to the composition of the refrigerant, there are single refrigerants and mixed refrigerants.
    According to the source of substances, there are natural refrigerants and synthetic refrigerants
    .

    The nomenclature of the refrigerant of the pharmaceutical cooling and heating cycle machine is represented by the letter "R", and the numbers and letters behind are written according to certain rules according to the chemical properties of the refrigerant
    .

    The selection of refrigerant is mainly considered from three aspects, whether it has better refrigeration performance, whether it is practical, and whether the substance has adverse effects on the atmosphere Theoretical cyclicity and thermodynamic properties
    .

      2.
    In order to be practical, the chemical stability and thermal stability of the refrigerant are better, it does not decompose or deteriorate during the refrigeration cycle, it does not corrode the materials of machinery and equipment, and it has no chemical reaction with the lubricating oil.
    In addition, it is reliable and non-toxic.
    Harmless, less flammable and explosive
    .

    3.
    Environmental acceptability.
    After the refrigerant is selected, according to its properties, it in turn requires the process arrangement, structural design and operation of the refrigeration system to adapt to it
    .

    These all need to be properly handled on the basis of fully grasping the properties of the refrigerant
    .
