Main options for BOX STORAGE include:

Box storage
Suitable for drying / storage of smaller quantities of potatoes or onions. Rows can be ventilated independently. Row length limited to 10-12 boxes. An accurate positioning of the boxes is important in order to limit loss of air. Closed boxes are needed for proper ventilation of onions.

Suction ventilation
Suitable for drying / storing larger quantities of potatoes or onions. A space of 40-50 cm between the two rows of boxes (covered by a sheet) is used to suck the air through the side walls of the boxes. Long rows are possible. Inlet and outlet hatches at same side of the building with complex suction chamber. Use of heater is difficult with this system.

Airbag systems

A space of 40-50 cm between the two rows of boxes (covered by an inflatable airbag) is used to blow the air through the side walls of the boxes. Long rows are possible. Inlet and outlet hatches at opposite sides of the building. Heaters can be used easily with this system.

Air mix unit/compact cooler
