Controlled-atmosphere storage combines refrigeration with management of oxygen, carbon dioxide and humidity to help preserve produce quality. The source material emphasizes limiting unnecessary air exchange while keeping goods and personnel moving efficiently.
Door and dock equipment considerations
- Insulated high speed doors are described between the controlled-atmosphere room and a buffer or corridor to shorten the time an opening remains open.
- For internal openings with little temperature difference and frequent traffic, the source also lists single-layer high speed roll up doors.
- A dedicated insulated sliding door is described with enhanced airtightness and an observation window so operators can check the room without opening the door.
- Personnel doors, double-acting traffic doors and dispatch-bay equipment can be selected for the surrounding buffer and loading areas.
