Low temperature maintenance: Dual cooling system provides stable thermal control for 24 hours or longer, helping preserve perishable food during transport and storage without dangerous temperature fluctuations. Fast freezing: Gel plates offer instant cooling with fast freezing capability, supporting cold chain requirements and delivering consistent performance during transport. Versatile uses: Temperatureadjustable refrigerant enables multiuse performance. Optimized for outdoor activities or laboratories, adapting to different environments. Insulated performance: Vacuuminsulated design delivers complete cooling and precise temperature maintenance for food refrigeration. An effective thermal barrier supports ice block preservation. Use scenarios Food transport and delivery: Keeps seafood, dairy, meat, and other perishables fresh from pickup to delivery, maintaining safe temperatures throughout transit. Outdoor and field activities: Camping, hiking, fishing trips, or picnics where reliable portable cooling is needed in varying outdoor conditions. Laboratory and field work: Suitable for laboratories or onsite testing that require controlled cooling of samples, reagents, or other temperaturesensitive materials.
