Temperature
sensitive goods in sea freight using passive cooling
A
big disadvantage in shipping or transporting temperature
controlled goods by sea is the long transport times.
Depending on the location of the receiver the transport
times can take up to weeks even months.
It is not easy to
protect temperature sensitive or temperature controlled
goods with passive
cooling, meaning insulation materials over such
long period of time so additional cooling techniques are
required. Another disadvantage of sea freight is the sea
container itself. Sea containers are made out of steel which
means that they transfer temperatures very fast and hard
through conduction. If we hereby realize that a ship can be
sailing in the open sun during the total day, the
temperatures can rise extremely high in the sea container.
Luckily most shippers know that if temperature controlled
goods are shipped, the sea containers are best place at the
lower locations on the ship and not at the top surface so
the sun will not shine directly on the sea container.

Cooling
technique for passive cooling in sea
containers
(patent pending)
To
offer a solution to the extreme weather
conditions in sea freight, the company
Krautz Temax, as producer of the Temax®
insulation, has developed a special
insulation technique which decreases the
extreme temperatures in containers
significant. This technique is based upon
an insulation technique which is used in
the building industry and has a patent
pending.

Insulation
is also used in the building industry to protect the
inside temperature of the building against the
unwanted outside temperatures. This in summer and
winter times. Also the Temax® insulation is used for
this application as cavity wall insulation, roof
insulation, floor insulation etc. When buildings
are insulated, the same problem is seen as with the
sea containers saying that buildings are standing in
the open sun during a long period of time which means
that the temperature of the materials as the building
materials of the roof of a building or the brick walls
of the wall or as the steel of the sea container rises
extremely influencing the temperature in the rooms of
the building or the room in the sea container. To
offer a solution to this problem air ventilation is
used. This ventilation creates an air flow so that the
warm temperature of the air between the heated
materials as the building materials or the steel of
the sea container is floated out of the construction.
The
drawing above shows a roof construction of a building
in which the Temax® insulation is used. The drawing
shows that the outer construction is not placed
directly against the insulation material. In the outer
roof construction, special holes are implemented which
make it possible for air to float between the outer
construction and the insulation material. This gives
the advantage that if the sun is shining directly on
the outer construction, heating- up the construction
materials as the insulation, the air flow will take
this warm air out of the construction. This
ventilation technique is decreasing the temperature
rising of the inner construction materials as the
temperature in room (B) significant.
This
cavity-wall insulation technique can also be
implemented on sea containers. Here fore the sea
containers need to be foreseen with ventilation holes,
protected with rain caps, so an air flow can exist in
the sea container. Next, two insulations are required
being a primary and secondary insulation. One
insulation is needed to resist the heat from the
conduction of the sea container which is attached to
the metal of the sea container. The other insulation
is to protect the temperature sensitive goods and is
wrapped around the goods. The ventilation has to take
place between the primary and secondary insulation.
This ventilation will be created by the sea breeze.
The
Temax® insulation used in this application can be for
one-way-use purposes or for re-usable purposes. Please
notice that in a re-usable application a return flow
must be organized when the insulation is build-out.
The insulation can also be build-in the sea container
on a permanent base.
This “cavity-wall” ventilation technique can also
be used in other packaging systems which are standing
in the open sun.
