The more stable the working climate is, the longer the
components last.
Electrical
enclosures and their high-performance components are indispensable for the
control of today's production processes. However, it is easy to imagine the
consequences when sensitive circuitry and modules become overheated: systems
shut down, creating the risk of production losses and the premature ageing of
components.
To ensure that
sensitive electronic components continue to function reliably in the long-term,
the temperature inside electrical enclosures should not exceed or fall below
defined limits. Tests have shown that an increase in temperature of as little
as 10 K shortens the lifetime of electrical components by more than 50 %.
This exemplifies
the effect of perfect thermal management of electrical enclosures ? it prevents
critical temperature fluctuations, avoids overheating and protects against the
formation of condensates. In this way, it contributes significantly to
increasing failure safety and prolonging the lifetime of electronic control
units.
Why thermal management?
The life expectancy of film capacitors decreases as the
ambient temperature increases.
Too hot ? too cold ? too humid ? broken. Protect your
electronic systems against stress.
To be able to
choose the most suitable thermal management solution, it is essential to start
by considering the location of the unit and the ambient temperature. This is
because the environment in the electrical enclosure can also be affected by
weather conditions, solar radiation or other external heat sources.
Regardless of
whether they are exposed to climatic or technical conditions, even particularly
low ambient temperatures impact on specific thermal management solutions. This
means that electrical enclosures may need to be heated to counter the effects
of excess cold and the associated risks of condensate formation such as
corrosion and short circuiting.
Another major
factor to be taken into account is the ambient air quality ? for example, if
the air is excessively humid or dust, oil or gas laden.
Pfannenberg's
thermal management solutions address all these factors and create exactly the
right conditions that sensitive electrical enclosure electronics need: a stable
operating environment that is ideally pitched.
Both internal thermal losses and external factors make
thermal management necessary.
Why Pfannenberg?
Our cooling concept provides unique flexibility.
One cut-out, all
possibilities: Our active cooling units, our air/air and air/water heat
exchangers have identical cut-out sizes and fit into the enclosures of all
cabinet manufacturers. This makes it possible to exchange the cooling
technology easily at any time, such as after an update of electrical enclosure
components or another adjustment to changed temperature conditions.
Machine and
plant constructors, end users and distributors enjoy this flexibility and
profit from high cost savings when equipping and modifying electrical
enclosures
1 enclosure
cut-out, 3 cooling technologies, 9 different devices ? for unique flexibility
and cost savings:
Construction of
one standardised enclosure cut-out.
Selection of the
appropriate cooling technology, also after completion of planning phase.
Easy exchange of
cooling technology when temperature conditions change.
Easier to stock
replacement devices for service cases.
Less time and
money needed for service and maintenance due to Plug & Play technology.
