Low-temperature quick-freezing is the key to long-term high-quality preservation of food. Rapid cooling allows food to quickly pass through the ice crystal formation zone, preventing the formation of large ice crystals in food cells. This avoids damage to the cell wall and perfectly maintains the original quality and taste.
The temperature of the quick-freezer is generally -15°C to -35°C. It is primarily used for the low-temperature rapid freezing of food, medicine, and medical items.
Required Project Information:
As cold rooms are fully customized, we require the following details to provide an accurate design:
We provide 3D renderings for each customer based on detailed parameters. This allows for an intuitive view of the actual construction effect and helps avoid errors during the assembly phase.




Polyurethane (PU) cold storage boards feature high moisture and water resistance. Rigid polyurethane has a closed-cell ratio of over 90%, making it a hydrophobic material that maintains thermal conductivity and prevents wall seepage.
