        We have long-term cooperation with logistics equipment research and development institutions to continuously improve the technical level of cold-chain packaging equipment.

        Each type of cold-chain packaging equipment has undergone continuous temperature testing at various extreme ambient temperatures. According to strict test procedures, it strictly abides by refrigerant pretreatment, temperature recorder pretreatment, simulated drug pretreatment and other material pretreatment process, which eliminates any environmental interference inside the test equipment.  Within the equipment, we adopt the multi-point data acquisition mode to eliminate interference from different locations inside the equipment.

        Our continuous temperature test is based on four environmental temperature change modes: high temperature in summer, low temperature in summer, high temperature in winter, and low temperature in winter. During the test, the environmental temperature fluctuates from -21℃ to 58℃, forming a complete chain of ambient temperature fluctuations to fully detect the working function of refrigerants and storage agent.
