Dragon-M Ventilation Unit for Container Storage

Air Preparation and Distribution for Container Vegetable Storage

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.

Model Examples

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.
