environment in which it’s installed. It must
be specific to a particular application.
The main considerations centre around
whether the enclosure is located in a cold
or hot environment, if that environment
is clean or dirty, and to what degree.
Conditions may also change over the
course of the working day, week, month
or year, so the final selection of an
appropriate cooling solution may not be
entirely straightforward.
Jason continues: “Enclosures that are
placed in a cool and clean environment
may find fan-and-filter units are more than
adequate, given a single device provides
more than 4 kW of cooling in ideal
conditions. However If the air is dirty, it is
still possible to take full advantage of low
ambient temperatures by using energy
efficient air-to-air heat exchangers to
provide any necessary cooling.”
For applications that require the
temperature inside the enclosure to be
lower than that outside it, a refrigerant
based solution may be the best option.
The new Blue e+ cooling unit range
from Rittal, with capacities up to 6kW,
can operate in ambient temperatures
up to 60°C yet also provide free cooling
when the external air is cooler due to the
innovative use of hybrid technology.
Air-to-water heat exchangers may be
used in even hotter conditions and the
water delivered to a remote location in
which the heat, up to 10kW from one unit,
may be dissipated more effectively and
with less effect on the temperature of the
surroundings.
