The control system includes a sealed chamber for storing products such as food products in a desired condition until scheduled for delivery. The conditions may be cooling, freezing, heating, dehydrating, rehydrating, etc., of fruit, bakery products, meat, or other products requiring rapid and controlled changes in temperature, humidity, or gases to preserve them. Alignment structure within the chamber floor spaces rows of product such as supported pallets apart from the sidewalls to define high and low pressure plenums. A sealing member extends from the chamber ceiling to one side of each row to form a seal therewith. The sealing member and palletized product, along with other seals within the chamber, divide the chamber into multiple volumes. One or more movable sealing baffles may be constructed for selectively forming a seal between a sidewall and the palletized product for a partially filled chamber. A fluid control unit injects gases of a selected type or temperature into the one volume and withdraws the fluid from the another volume to cause fluid to flow through the palletized product. To increase floor space and allow maintenance with food product in the chamber, the fluid control unit may be mounted outside the chamber interior. The system may be used with multiple row, multiple tier chambers. By placing the sealing members in selected positions relative to the rows of palletized product, a number of different fluid flow patterns through the food product may be achieved.
