On March 30, at the 2026 Shanghai International Lure Fishing and Equipment Exhibition, Haier Freezer made waves by launching the industry's inaugural product specifically designed for sea fishing aficionados—the first-ever household-grade -60℃ ultra-low temperature freezer. The accompanying white paper highlights a common issue with traditional -18℃ freezing methods: they often result in the formation of sizable ice crystals within cells, which can pierce cell membranes and cause nutrient depletion. Conversely, a -60℃ ultra-low temperature setting, coupled with swift cooling, can effectively curb microbial proliferation, diminish enzyme activity, preserve the integrity of cell structures, and seal in the nutritional value and flavor of food ingredients. The Casarte -60℃ ultra-low temperature freezer leverages proprietary ultra-low temperature dual-engine precision freezing technology, ensuring a temperature variance of less than 3℃ within the unit. It operates at a mere 38 decibels, adheres to top-tier energy efficiency standards, and has earned the industry's inaugural certification for exceptional performance among household-grade low-temperature freezers.
