3. PRODUCT LOADING
Proper air circulation in the insulated box, air that can
move around and through the load, is a critical
element in maintaining product quality during
transport. If air cannot circulate completely around the
load: hot spots or top-freeze can occur.
The use of pallets is highly recommended. Pallets,
when loaded so air can flow freely through the pallets
to return to the evaporator, help protect the product
from heat passing through the floor of the truck. When
using pallets, it is important to refrain from stacking
extra boxes on the floor at the rear of the truck,
because this will cut off the airflow.
Product stacking is another important factor in
protecting the product. Products that generate heat,
fruits and vegetables for example, should be stacked
so the air can flow through the product to remove the
heat; this is called "air stacking" the product. Products
that do not create heat, meats and frozen products,
should be stacked tightly in the centre of the box.
All products should be kept away from the sidewalls
of the body, allowing air to flow between the body and
the load; this prevents heat filtering through the walls
from affecting the product.
It is important to check the temperature of the product
being loaded to ensure that it is at the correct
temperature for transport. The refrigeration unit is
designed to maintain the temperature of the product at
the temperature at which it was loaded; it was not
designed to cool a warm product.
SOME ADVICE
Before loading
• Pre-cool the inside of the insulated body by lowering
the temperature for about 15 minutes.
• Evacuate the humidity existing inside the box by
carrying out a manual defrost. For CITIMAX500/700
units, the defrost mode can only take place when the
box temperature lower than 4°C.
• Evaporator fans are protected by safety grills. In the
event of heavy duty use of the unit, ice can accumulate
on the grills. It is therefore recommended to clean
them regularly by means of a small brush. The
operation MUST be done when the unit has been
SHUT DOWN.
When loading
• To be carried out with the unit stopped.
• It is recommended to open doors as little as possible
to avoid the intake of hot air and humidity.
• Select the temperature by means of the thermostat,
according to the transported goods.
•
Check
the
internal
temperature of the goods
being loaded (using a probe
thermometer).
• Take care not to obstruct
the air intakes on the
evaporator section and the
ventilation ducts.
Load spacers
Load on pallets
• Leave a free space of about :
- 6 to 8 cm between load and front wall,
- 20 cm between the top of the load and the roof,
- between the floor and the load (gratings, pallets).
• Do not forget to close the doors.
• Before closing the doors, check your load once more
and see that nobody is
shut inside the box.
NOTE :
For
stationary
utilization,
we
recommend to place the
body in the shade.
