Boss Zhao, who runs a frozen food store in Northeast China, was always troubled by the "shutdown" of his cold storage unit every winter a few years ago. Once, when a cold wave hit and the outdoor temperature dropped to -32℃, the ordinary cold storage unit in his store suddenly stopped working. Overnight, two boxes of frozen meat thawed and spoiled, causing a loss of nearly 1,000 yuan. It wasn't until he replaced it with a professional low-temperature cold storage unit last year that he completely got rid of this trouble. Even in extreme weather of -30℃, the unit can operate stably.

        The "anti-freezing secret" of this low-temperature cold storage unit lies in the design of its core components. The compressor shell is made of thickened aviation alloy material, which can resist low temperatures of -40℃. Even if a thin layer of ice forms on the body, the internal parts will not be affected; the outer layer of the pipeline is wrapped with three layers of cold-proof insulation cotton and an anti-freezing coating to prevent cracking and freezing blockage at low temperatures. Boss Zhao said that in the past, the pipelines of ordinary units had to be wrapped with several layers of old cotton quilts every winter, but this one doesn't need additional protection at all, which saves a lot of trouble.

         What's more considerate is its intelligent defrosting system. Northeast China has dry winters, so the evaporator is prone to frosting. Ordinary units require manual defrosting, which takes two hours of shutdown, during which the temperature will rise. However, this unit can monitor the frost thickness in real time. Once it exceeds 5mm, it will automatically start the low-temperature defrosting mode without shutting down the machine throughout the process, and the temperature fluctuation inside the warehouse does not exceed ±1℃. In addition, its low-temperature start-up protection function is also very practical. Before starting the machine in the morning, it will preheat the compressor for 3 minutes to prevent start-up failures caused by low temperatures, and there is no need to press the start button repeatedly as before.

Now, Boss Zhao's frozen food store can operate normally even if the temperature is above -25℃ for a week in winter. He often tells his peers: "When running a frozen food business in the north, choosing the right low-temperature cold storage unit is more important than anything else. It can not only reduce losses but also save worries!"
