Risks associated with the lack
of thermal control
Random breakdowns and production halts result
in heavy losses
Thermal control of enclosures extends the service life of the components and
reduces their breakdown rate.
Sudden production halt
The appearance of hot spots increases the breakdown rate and endangers the
production process.
Example
Electronic equipment
Most electronic industrial control systems are equipped with axial fans for their own
thermal control. A failure of the fan can lead to a production halt.
Reduced service life of the fan is one consequence of the enclosure heating up.

Service life at 60°C (L10 at 20°C): 20000 h.
The service life of the equipment can drop from 50000 h to only 20000 h.
The internal temperature increases with a high degree of IP
In agressive atmospheres: dust, humidity, chemical agents, high temperatures, etc.,
the equipment is installed in industrial enclosures (IP54) in order to protect it from the
external environment. Nevertheless, it causes a reheating phenomenon which,
if left unchecked, will be responsible in the short term for a halt in the operation
of the components.
Example
Variable speed drives
A variable speed drive controlling a 45 kW (60 HP) motor is programmed to work at
temperatures ranging up to 50°C or 60°C.
The power dissipated by this variable speed drive inside the enclosure can reach 1360 W.
This contribution of heat inside the enclosure will cause the top temperature to rise
to 60°C and probably cause a halt in production.
Example
Batteries – Accumulators
Manufacturers recommend installing batteries in environments where the controlled
temperature is 15°C... 25°C.
Cold slows down the battery charging and discharging cycles. Heat increases the
evaporation of water in the electrolyte and speeds up the oxidation of the plates.
Using batteries at temperatures above the recommended value therefore reduces
their service life.
Reduction of the service life of the components
The service life of the components is considerably reduced if the temperature
and humidity in enclosures are not controlled. Repeated sudden variations speed
up the aging process.
