Air Preparation and Distribution for Container Vegetable Storage
Dragon-M is a ventilation unit for container-based vegetable storage. The unit prepares air before it enters the storage zone and then delivers it through the distribution system. Depending on the project, it can combine recirculated chamber air with fresh outdoor air and include heating, cooling, filtration and high-pressure supply components.
Container storage requires controlled air delivery to many individual crop volumes. Dragon-M supports this by creating a stable prepared-air flow that can be adapted to the current storage mode: drying, cooling, holding, warming or controlled ventilation.
System Concept
The unit is built around the idea of air preparation outside the crop volume. Return air from the room can be mixed with outdoor air, conditioned if required and then supplied back to the storage space. This makes the microclimate strategy more flexible than simple direct ventilation.
A regulating damper controls the outdoor-air share, while the supply fan provides the pressure required for the duct and container distribution system. In cold climates, a heated intake arrangement helps protect the air inlet and damper zone from freezing.
Configurable Blocks
- Recirculation and fresh-air mixing: the unit can operate with return air, outdoor air or a controlled mixture.
- High-pressure supply fan: provides the airflow and pressure needed for container storage distribution.
- Heating block: supports drying, curing and low-temperature operating modes when heating is required.
- Cooling block: can be included where mechanical cooling is part of the storage technology.
- Filtration: outside-air filters can be specified to protect equipment and storage rooms from coarse contamination.
- Automation integration: the unit can be integrated into the site climate-control system, including Orion-based control logic.

Application in Storage Projects
Dragon-M is selected for projects where container rows, chamber layout and storage technology require a defined air-preparation unit rather than only local fans. The correct configuration depends on crop type, loading system, required cooling capacity, outdoor design temperatures, storage period and automation logic.
Because each project has different resistance and airflow requirements, model selection should be made together with the duct layout and the storage-control concept. The result should be a coordinated system, not a collection of separate components.
