Insulated panel used for ceiling and wall mounting, while cold storage floor Made from insulated panels, including EPS with density 22kg/m3 and PU with density 34kg/m3, ensure the surface is flat and non-slip.

Modern cold storages are also equipped with control cabinet, helps display parameters of temperature, pressure and incidents, helping users easily monitor and manage.

Storage temperature of vegetables and fruits divided into groups

Below freezing temperature (-1°C to 0°C)

This is a temperature close to freezing but not quite frozen. Vegetables that can be stored at this temperature include those that can withstand cold without freezing, such as some greens and fruits.

Freezing temperature (0°C)

At this temperature, the water in vegetables can begin to freeze. This is the ideal temperature for vegetables like broccoli, strawberries and carrots, helping them stay fresh for a long time without damaging their structure.

Just above freezing (0°C to 5°C)

This group holds vegetables that are susceptible to spoilage if frozen completely but still require low temperatures, such as leafy greens, tomatoes, and grapes. This is the most common temperature in cold storage for vegetables.

From 5°C to below 10°C

This is the ideal storage temperature for fruits and vegetables that don't tolerate cold well but still need a cool environment to stay fresh, such as cucumbers, carrots, peppers and grapes.

From 10°C to 15°C

At this temperature, tropical fruits such as bananas, mangoes, papayas, and some cold-sensitive vegetables such as pumpkins and squash will be better preserved.
