OUTSTANDING COOLING FROM ABOVE
Rittal has developed a roof-mounted version of its award-winning
and highly energy efficient Blue e+ cooling units; these are
designed for enclosures of 800 x 600mm (W x D) upwards and
deliver a cooling output of 1.3 kW.
The new roof-mounted units also feature within the new VX25
large enclosure system as an integrated solution.
Roof-mounted climate control units are the top choice in control
and switchgear applications where there is a lack of space on the
front and side panels. This could be due to physical location of
the enclosures and minimal gangway clearance, but could also
be due to an abudance of interlocks, switches or other controls
preventing adequate space for a wall mounted cooling unit.
Air routing within the enclosure is also optimised; the cold air is
blown down the front of the enclosure and drawn back up the
mounting plate, thereby effectively dissipating the heat from top-
mounted components such as frequency inverters.
The new roof-mounted cooling units of the Blue e+ series, like
the existing wall-mounted units, work with a combination of heat
pipe and conventional compressor technology.
Energy consumption is very low because neither a compressor
nor a pump is required when the cooling units are operating
on the heat pipe; only the fans that circulate the air by the heat
exchangers need an electricity supply. This cooling method works
particularly well if there is a large temperature difference between
the inside of the enclosure and the surroundings.
AVERAGE ENERGY SAVINGS OF 75 PER CENT
The additional compressor within the cooling units only kicks
in when a larger cooling output is required. All the active
components operate with speed-controlled drives so the cooling
output always matches what is required, ensuring less energy is
consumed.
Overall, depending on the ambient conditions and the
application, the cooling units of the Blue e+ series use on average
75 percent less energy than conventional compressor cooling
units do. Lower temperature deviations within the enclosure
means that the service life of the components installed is
extended.
In addition, the new units have a multi-voltage supply making
them easy to operate at all common mains voltages and
frequencies. This is a huge benefit, especially for engineers who
sell their machines worldwide.
INTUITIVE AND COMFORTABLE OPERATION
Blue e+ roof-mounted systems are easy and intuitive to operate,
using a touch display for basic settings and to read status
messages. The touch display can also be integrated into the door
of the enclosure if required.
Another option is the IoT interface, which makes it simple to
integrate the cooling unit in an Industry 4.0 (IoT) environment.
COMPLETELY READY-ASSEMBLED
The Blue e+ cooling unit is a feature in the new Rittal integrated
solution which consists of an enclosure with built-in climate
control.
The cooling unit is installed in the upper section of the VX25
enclosure as a plug & play. The touch display is built into
the enclosure door and the unit can be easily removed for
maintenance.

VX25. SYSTEM PERFECTION.
There are always two versions of this
enclosure - real and digital. The maximum
data quality of the VX25 ensures greater
flexibility for configuration, manufacturing
and assembly. And with the “digital twin”,
the person who knows your company best
– you yourself – can plan, order, process
and do much more besides.
