| Passive
cooling or passive packaging in air cargo or air freight |
|
When
temperature sensitive products or goods are shipped in
airfreight or air cargo, a cold chain or temperature
controlled supply chain needs to be created from the shipper
to the receiver. This cold chain can be created with active
cooling systems or passive
cooling systems in which the shipper or other
actors in the cold chain as producer of the temperature
sensitive products, transport companies, freight forwarders,
distribution centers, airliners, cargo handling, etc… can
choose which kind of cooling is most suitable as long as the
required temperature can be kept within its limits. When we
talk about passive cooling we mean that no electrical or
mechanical systems as cooling engines are used to cool the
surrounding air on the temperature sensitive products and
that the products are protected with insulation materials.
The goal of the insulation material is to protect the
temperature of the temperature sensitive product against
unwanted external or outer temperatures. Due to the
efficient closing of the cold chain (no CCP’s) and the
cost efficiency more and more companies are looking at the
possibility to use passive cooling in air freight cargo in
which the thermal blankets are the most used applications
which are used to wrap or insulate pallets, airplane
pallets, air cargo containers etc… On this website you can
find more information and applications on passive cooling
systems and techniques for single use or multiple use
purposes. |

Example
temperatures in Air freight: (Brussels -
Dubai - Singapore) with passive packaging
|
|
The
graphic below shows a possible temperature flow (blue
line) of outside temperatures that can occur during an
air freight transport. The brown line represents the
ideal temperature for your goods. The green zone
represents the border with maximum and minimum
temperature limits which may not be crossed. The
temperature of your goods has to be within this green
zone to maintain the quality of your goods. The goal
of a passive packaging is to insulate your goods in
such a way so the temperature stays within the green
zone during the total air freight transport time
(black line). To achieve this, the insulation material
or way of packing needs to be tailor made according to
the transport situation and requirements in which
additional cooling techniques may be needed.

Departure
sender
– Airport Brussels
A = Transport
from sender to Airport (= conditioned trailers / trucks)
B
= Storrage at the forwarder (= conditioned cool
chamber)
C
= Preparing the airplane pallet (= usualy not
conditioned)
D
= Tarmac time
= Driving the airplane pallet to the air plane + loading (=
outside temperatures in Brussels)
E = Flight
Brussel - Dubai (= in this example not conditioned)
|
|
Stopover
in Dubai
F = Landing +
taxi to unloading place
G
= Tarmac time
= Onloading the goods (= outside temperature in Dubai)
H
= Storrage in Dubai airport (= in this example
in a conditioned cool chamber)
I
= Tarmac
time = Driving the airplane pallet to the air
plane + loading (= outside temperatures in Dubai)
J = Flight Dubai
– Singapore (= in this example not conditioned)
|
|
Landing
in Singapore
K =
Landing + taxi to unloading place
L = Tarmac
time
= Onloading the goods (= outside temperature in Singapore)
M =
Storrage in Singapore Airport (= in this example in a
conditioned cool chamber)
N =
Transport from airport to customer
(= conditioned trailers / trucks)
