5.1 Storage and stacking
One of the main concerns to take into account when storing goods, is how to
ensure proper air circulation in the isothermal cold room. If the air cannot circu-
late freely throughout the cargo, ice or warm areas will almost certainly develop,
which could irreparably damage the goods.
One of the first tips to avoid this, is to store the goods on pallets. If loaded in a
proper way, palletized goods will allow the air to circulate freely into and out from
the evaporator. Furthermore, they will be protected by the pallet from the heat
passing through the floor of the trailer.
Proper air circulation is extremely important too when stacking the goods. In fact,
some goods tend to produce heat, while others don't.
Fruit and vegetables, for example, belong to the first group. In this case, the
goods should be stacked in such a way as to ensure good air circulation through
the cargo. Those items which do not generate any heat, such as meat, deep
frozen products and fresh packaged products, should be stacked in the center of
the cold room.
Avoid positioning the goods leaning on the cold room walls. In fact, the walls fil-
ter heat from the environment, which is most damaging to this type of goods.
The DFZ ZANOTTI refrigeration units are designed to keep the goods at their
loading temperature.
The DFZ ZANOTTI refrigeration units are not suitable to refrigerate warm prod-
ucts.
5.2 Mobile partitions
There are different minimum clearances at which mobile partitions should be
placed, depending on the DFZ ZANOTTI refrigeration unit model. Such clear-
ances are:
• DFZ 435: 1400 mm / about 4' 7 1/2"
• DFZ 465: 1800 mm / about 6'
• DFZ 495: 2700 mm / about 9'
The air pipes of the evaporator should always be left undisturbed.
