(CA)Controlled Atmosphere Storage Solutions
Keep Your Fruits & Vegetables Fresh 3-5 Times Longer
Product Features
1. Introduction
A controlled atmosphere storage adjusts oxygen, carbon dioxide, and humidity levels to slow down the natural ripening and aging of fruits and vegetables. By creating a low-oxygen, high-humidity environment, it can extend produce shelf life by 3–5 times while preserving color, texture, and nutrients. Automated sensors and control systems keep conditions stable and energy use low, making CA storage an efficient solution for high-value fresh goods.

2. Advantages
