By Increasing Nitrogen Content

This product has been discontinued and removed from our shelves.

The CQT controlled atmosphere storage system is a piece of marine food preservation equipment for mid to large vessels.

How it works
The nitrogen fresh keeping system lowers the oxygen concentration by replacing the air inside the storage unit with high-concentration nitrogen to slow down the deterioration of vegetables and fruits. The humidifier and ethylene-removal are used to adjust the humidity and ethylene content to extend the storage period for vegetable and fruits.

1. The fresh-keeping results are good. The storage period of vegetables and fruits can be extended 30 days while maintaining quality.
2. High automation level: the controlled atmosphere storage system can run automatically and has a simple operation.
3. A special safety system is used to guarantee the safety for the crew as well as the equipment and storage space.
4. The parameters for the storage environment are shown in real-time in the time management interface.

Fresh-keeping effect
Lettuce keeps 30-45 days.
