For an active temperature management we offer high quality
STULZ-Cosmotec A/C units under Triton brand. Compact A/C ETE units
are designed for cooling of equipment in every single data cabinet
(RDA cabinets and RIE cabinets with IP54 protection). These A/C
units are intended for both industrial and office surroundings
thank to its RPM management of a cooling ventilator in compressor
circuit. The A/C unit adjusts the RPM speed of the ventilator,
which is a major cause of a noise. The A/C RPM adjusment is based
on a current use of the cooling output inside of the cabinet. It
has a very possitive affect on the noise reduction of the unit when
maximal output capacity is not necessary.

1.inside circuit, which cools down all installed equipment and
enters the A/C unit, where the hot air is transferred into a
cooling medium
2.cooling circuit controlled by the compressor, which is cooled by
an air stream which cools cooling medium
Thank to its arrangement the air from the outside is not mixed
with the air from the inside of the cabinet. Also humidity inside
of the cabinet is not increasing. Improper humidity can also
condense on the top of the equipment which can lead to its damage.
It is very important to set up the A/C unit correctly and consider
the surrounding temperature and humidity. It is also possible to
equip our data cabinet with a door sensor, which shuts the
compressor automatically down when the door is opened.
The A/C unit has a possibility of the controlling electric unit
installation, which includes thermostat in two different part of
the cover. There are several possibilities how to install such A/C
unit. The A/C unit can suck the hot air and blow the cold air along
the side panels of the cabinet or it can be installed to the
front/rear side accoring to the exact requirements.
For a proper function of the A/C unit is necessary to provide
with sufficient air circulation ant its appropriate temperature.
The unit has special sensors which control a sufficient space from
surrounding objects. For more information please refer to the
manual of each A/C unit.
A/C INSTALLATION
In order to utilize the maximal potential of A/C units with
cooling air direction right according to all equipment needs, we
supply RDE and RIE cabinets with installation adapters. It is a
metallic panel which ties with screws to the large-sized opening at
the top of the cabinet where the installation of A/C is required.
Adapters are symetric which means that rotating or even turning is
simple. All sizes of adapters are shown in table below. For an easy
access to the controlling panel it is possible to install in two
positions with a simple plug into the connector (see installation
manual).
The A/C unit 800mm wide is intended for data cabinets with 800mm
width only.
The A/C unit 600mm wide is intended for data cabinets with 600mm
and 800mm width.

The A/C unit can
be installed in the way to absolutely fit all requirements to
provide with a cold air according to its needs.
There
is an opening located at the top of the RIE and RDE cabinet, which
requires an installation of an adapter. An appropriate reduction
can set the right direction of the A/C unit and it also sets the
stream of the hot/cold air along the sides or along the front/rear
sides of the cabinet.
Operation conditions:
The ETE A/C unit is designed for a function in horizontal
position as well as roof units for free-standing cabinets. It is
also necessary to transport such device in horizontaly and also
instally accordingly!
We offer adapters for an installation into RDE and RIE data
cabinets, which seal the A/C unit at the cabinet body and which
also would point direction of the cold air flow inside.
The units contain a drip tray, which absorbs condensate air
humidity from the cooled space, which in the following evaporating
tray exhaled in the environment. In case of increased condenser
formation (which can happen by higher air humidity, lowered
temperature inside the cabinet, the door left open...) it`s
necessary to install safety condensate draining pipe and follow the
mounting instructions described in the attached manual.
Operation environment:
Min. ambient temperature in the working condition:
+20 ºC
Max. ambient temperature in the working condition:
+50 ºC
Adjustable temperature range: 25 – 45 ºC
Recommendation:
With regard to the demand of a maximal life-time of the unit`s
equipment, those are the recommended parameters of the inner
environment of the cabinet.
Temperature limits: from +10 till + 40
ºC
Relative humidity: 30 – 90 %
Surface temperature of the inner equipment of the cabinet should
not fall below the dewpoint temperature.
