Walk-in Freezer sandwich panel manufacturer

Walk-in Freezer primarily uses PU/PIR sandwich panels, which offer excellent thermal insulation and superior waterproofing and moisture resistance. Different panel thicknesses are suitable for different temperatures and application scenarios. Generally, the thicker the panel, the better the insulation performance.   For walk-in freezer units with different temperature requirements, different PU/PIR sandwich panels can be selected:   1. -18℃ ~ -25℃ cold storage: 150mm PIR sandwich panels can be used for storing various aquatic products, meat products, and frozen foods;   2. -25℃ ~ -30℃ deep-temperature cold storage: 180mm and above PIR sandwich panels can be used for long-term storage of high-end seafood and meat, as well as freezing of ice cream and dairy products;   3. -30℃ ~ -40℃ ultra-low temperature cold storage: PIR sandwich panels with a thickness of 200mm or more must be used for long-term storage of deep-sea aquatic products, high-end seafood, and high-end beef and mutton.   4. Deep cryogenic storage at -40℃ and below: Requires 250mm thick PIR sandwich panels for the long-term preservation of vaccines, plasma, biological samples, viral strains and other biomedical and research materials, special industrial materials (such as aerospace materials and chemicals) and rare agricultural and insect specimens.
