PU panel cold rooms have become an essential solution for the storage of vegetables and fruits, offering excellent insulation and temperature control to preserve freshness and extend shelf life. PU panels are renowned for their exceptional insulation capabilities. The closed-cell structure and high density of PU panels effectively reduce heat transfer, ensuring consistent internal temperatures and minimizing energy consumption. This is crucial for maintaining the quality of perishable produce such as vegetables and fruits.
| Product Explanation: PU panel cold rooms are designed to maintain specific temperature and humidity levels to preserve the quality of vegetables and fruits. For example, leafy greens and root vegetables typically require temperatures between 0°C to 4°C, while fruits like apples and pears may need slightly higher temperatures of around 2°C to 5°C. Humidity control is also essential, with leafy greens needing high humidity (around 90% to 95% relative humidity) to prevent wilting. |

1. Panels For Cold Room for vegetables and fruits
Good waterproof performance Pu cold storage board with moisture and water resistance. The rigid polyurethane has a closed-cell ratio of more than 90% and is a hydrophobic material. It does not increase the thermal conductivity due to moisture absorption, and the wall surface will also seep.
Good sound insulation The porosity of the pu material is stable. It has a closed-cell structure, which has excellent heat preservation performance and resistance to freezing and thawing and sound absorption.
Strong resistance to deformation Strong resistance to deformation, not easy to crack, stable and safe finish.
Fire retardant and high-temperature resistant Pu is a flame-retardant self-extinguishing material after adding flame retardant. Its softening point can reach above 250 °C, and it will only decompose at higher temperatures.

FAQ
1. What temperature range and panel thickness are optimal for vegetable/fruit storage?
Vegetables and fruits typically require 0°C to +5°C for preservation. For this range, 100mm-thick PU panels are ideal. Thicker panels (e.g., 150mm) are used for freezing meats/seafood (-18°C), but 100mm balances insulation efficiency and cost for produce. Panels with 40–46 kg/m³ PU density ensure minimal thermal leakage, reducing energy costs by up to 30%.
