Summer Heat to Winter Cold without Rotating Fans
|
Outdoors, there are many reasons to be careful about temperature.
Basically, most providers of components to computer manufacturers
specify a fairly narrow temperature range. Heat can be a problem in any
high-performance system and as rotating fans are unsuitable for mechanical
reliability reasons, alternative cooling methods must be utilised.
Our computers are built to work reliably in extreme temperature conditions like
desert heat, arctic cold and humid jungles. To accomplish this, thermodynamic
specialists design our computers. Then, our products are pushed to the limit in
test chambers. In addition to tough testing, years of rugged use in the field
ensure reliability in the most demanding situations.
No Rotating Components
Our computers do not use rotating fans because vibration and shock often results
in a broken fan, which will crash the computer. In addition, fans can also force
dirt and moisture into a computer, and thus be the weakest point in a computer's
design.
Our computers can be equipped with either rotating or non-rotating hard drives.
This ability to choose is important, because storage
devices can often be the bottleneck component. Maximum temperature performance
can be achieved through non-rotating discs.
However, in cases where the capacity of a flash drive is not large enough,
the temperature is reasonable and the mechanical wear and tear is moderate,
our computers provide high performance with rotating drives.
Chemical Test Procedure
Chemical test are performed by exposing the computer to a
chemical solution for one hour in a high temperature (80°C). To successfully
pass the testing, the computer is washed clean and should look and work in
perfect order. The display screen and chassis must be in "new condition" without
stains or damage.
Flammability
Computers should never be the cause of fire. However a computer that is not
designed with fire resistant features can be the "ignition" of a fire resulting
in extensive material damages and human injuries. JLT computers will not start
fires, nor will they help promote fire.
