• To maintain the Temperature of the Product

• It is not designed to reduce or increase the

temperature of the product

• It relies on good air circulation within and

around the load

Transport Refrigeration :

What is its Purpose ?



Product TemperatureProduct should always

be cooled to the requiredtemperature before being

loaded.

Transport refrigerationequipment is designed to

maintain temperatureonly.

Product should be loaded from arefrigerated loading bay.



Different Containers

Plastic wrap will act

as a vapor barrier.Sometimes it is usedto trap in moisture,

other times to keep itout.

It will always reduce

the air circulation inand around the

product.

Fresh FrozenProducts Products

Holes in product

packaging allow air

to circulate among

the produce.



Ensure

• Container is clean

• Container & seals are in

good condition

• Reefer is well maintained

and pre-tripped by trained

technicians

Inspect Equipment



Removes the heat

that has entered thebody from the sun.

Pre-Cooling the Container

Pointless if proper

loading bay not

provided or unit leftoff power after

packing.



Loading to the ceiling will cause short

cycling

Short Cycling

Observe load Line



Pallet Loading

Minimum

100mm fromthe rear door

Properly loaded pallets

should allow air to flowaround and in between

the boxes.

Spacers will help

stabilize the load and

ensure good airflow.



Pallets should allow airflowthrough and under the load

Orientation should allow airflow

to the rear of the body

Correct Pallets use



• Inspect the unit to be loaded

• Pre-cool the box preferably until setpoint

• Switch off the unit

• Load product at the correct temperatureand in the correct manner

• Close doors

• Start up unit

• Ensure correct setpoint

Loading Procedure



Excessive space between

the load

Result: Airflow

doesn’t extend the fulllength of the container.



Load placed in the rear of

the container

Result: Short Cycling



Load placed in the front of

the container

Result: Air is not forced

through the interior of the load.



Summary : Good loading practices• Supply a well maintained clean reefer

• The refrigerated vehicle is not designed tocool products but to keep products cool.

• Pre-cool the container

• Poor air distribution is one of the primary

causes of product deterioration even when

unit capacity is more than adequate.



Summary : Good loading practices• Only load cargo at the desired carrying

temperature• Ensure load is stacked to provide proper

airflow

• Obstruction anywhere around the load can

result in hot spots.

• Run the unit from the time it’s loaded un-tillthe time it is unloaded
