CORROSION RESISTANCE
RITTAL
ENHANCED
FOR EXTREME
APPLICATIONS
The new Rittal VX25 large enclosure system
delivers significantly enhanced value to
electrical engineering companies thanks to
its technical features, ease of assembly and
high levels of safety. Now, new versions of
the VX25 are available in stainless steel and
NEMA 4X to enhance corrosion protection
and to ensure the equipment within it is
shielded from dust, as well as from splashes
and jets of water.
The new Rittal VX25 large enclosure system
is now available in stainless steel to deliver
the highest level of corrosion resistance. The
frame structure, doors, panels and the gland
plate, as well as all the external parts such as
180° hinges and comfort handle variants, are
all made of stainless steel.
While the sheet steel and stainless-steel
enclosure types have IP 55 and NEMA 12
protection categories as default, the optional
NEMA 4X version with its corresponding IP 66
category protection offers greater protection.
This means that the electrical and electronic
equipment in the VX25 is protected from
dust, water splashes and jets, even in the
most demanding of environments.
In order to achieve the high NEMA 4X
protection category, the enclosure
underwent, among other things, a water
jet test. This procedure (“hose-down” test)
involved examining any gaps with seals
for leaks using a jet of water with a flow
rate of over 240 litres per minute for a test
period of 40 min/30 s (6 mm/s per seal
length). The tests confirmed that no water
would penetrate the enclosure, under
comparable conditions.
In addition, the tests included a check of
the dust protection, corrosion resistance,
and protection against damage caused by
external ice formation.
The two VX25 enclosure variants have an
almost identical design, which means that
the interior engineering of the stainless-
steel enclosures can also be applied,
unchanged, to the NEMA 4X enclosures,
saving electrical engineering companies
both time and money.
Any requirement for energy-efficient
cooling of VX25 stainless steel enclosures
can be provided through the new Blue e+
cooling units, which are also available in
stainless steel.
