The Elektro Tipp - Combi Climate Glands
1. Felix G. Hensel
Managing partner of
Gustav Hensel GmbH & Co. KG
Dear Reader,
Electrical installation presents great
demands on a enclosures technology,
especially when it is installed outside.
It is also true for thermoplastic enclo-
sures in high degree of protection, which
are particularly well-suited for outdoor
installations.
Hensel is the specialist in this area.
The external influences like intense sun
rays, rapid temperature changes such as
between day and night and high humidity
can cause condensation to form in other-
wise hermetically sealed enclosures.
The consequences may be corrosion,
short circuits or other damage that may
severely hinder the proper functioning of
the electrical installation.
There are some targeted measures and
solutions to these problems that have
proved extremely reliable in practice.
The measures include climate glands
and ventilation flanges which can provide
permanent and reliable solutions for out-
door installations. Please consult Elektro-
Tipp or simply request further information
from us.
Thank you for your trust and we are look-
ing forward to continued successful and
pleasant cooperation with you.
Sincerely
How and when does condensed water forming appear?
The ELEKTRO
Customer information for electro-technical specialists 3/2011
Condensation in boxes is parti
cu
larly
common in outdoor installations.
The rapid change in temperature
(day/night, changes in weather,
intense sunshine) or load changes
in the equipment can cause
condensation to form on the walls of
closed boxes on the inner surfaces.
To prevent problems such as
corrosion, electrical short circuits and
in some cases complete equipment
failure, targeted action needs to be
taken.
When does a box start
to sweat?
Condensed water in enclosures with a high

Indeed,
there is moisture
inside the box!? The lid
is fogged up inside!

Prize for extraordinary success in
doing business with India goes to
Hensel
As part of this year’s traditio
nal
annual meeting of the Ger
man-
Indian chamber of commerce, the
”Hidden Champion” or the most
suc
cessful German-Indian joint ven
ture was honored on June 16th
in Düsseldorf. The German-Indian
chamber of commerce honors com
pa
nies whose dynamic development
and successful strategies make a
sizeable contribution to moving both
countries forward.
Picture: Nirmal Bhogilal, president of the German-Indian
chamber of commerce, handed out the certificate and
plaque to Felix G. Hensel, managing director of the
Gustav Hensel GmbH & Co. KG and Rajan Rajesh,
managing director of Hensel Electric India.
Felix G. Hensel and R. Rajesh in their
short presentation quickly made it
clear that the company is not only
growing in Europe but in Asia as well.
”We began moving into the Indian
and South-East Asian markets
with our own subsidiary back in
2002,” recalled Felix G. Hensel
as he expressed satisfaction with
the way Hensel Electric India has
developed since then. ”Since that
point, the company has become an
acknowledged specialist in top-quality
electrical installation and distribution
systems in the Indian and South-East
Asian market.”
Today more than 120 employees,
who work in an area of more than
5,000 square meters, are supplying
the Indian and Asian markets with
our products. The forward-looking
investment in a large site ensures
that Hensel will be able to go on
expanding over the coming years at
its Indian site.
Noted for you:
How and when does condensation
appear in enclosures with high degree
of protection and what does the safety
standard IEC 60 364-5-52 state?
Measures to prevent condensation from forming in boxes...
1. How does condensed water forming appear?
The extent of water saturation in
the air (humidity) depends on the
temperature.
In case of large difference in the air
temperature inside and outside of the
closed box then condensation will
form in boxes.
2. Where does condensed water forming occur?
3. WHAT does the IEC 60 364-5-52 safety standard state:
IEC 60 364-5-52 “Erection of low-
voltage installations”,
Chapter 52: Wiring systems,
clause 522.3.2 stipulates:
“If water can accumulate or
condensation water can form within
wiring systems, precautions for the
water evacuation must be taken.”
The standard for cable junction
boxes specifies a ø 5 mm
condensension hole.
Equipment switched on.
The warm interior air increases humi
di
ty, that enters with the ambient air
as enclosures are not gas-tight.
Equipment switched on.
The temperature in the box is generally
higher than the external temperature
due to the dissipated heat.
Equipment switched off.
The interior temperature sinks when
the equipment is switched off.
The moisture in the air condenses
and settles on the inner surfaces.
Example: Load change in processing
“Sweating” boxes primarily occur
in locations where temperatures
tend to change:
I.e. primarily in protected and
unprotected outdoor installations.
Indoors, e.g. close to large gates,
washing lines, washing rooms, in
agricultural buildings and other
places)
3. It is generally impossible to prevent the formation of condensed water in closed
enclosures in installation areas with large temperature differences.
The combi climate glands prevent
condensation caused by rapid
temperature changes, changes in
the weather, intense sun shine etc
from accumulation in boxes with high
protection classes.
The benefit of the new combi climate glands:
Cable entry and simultaneous ventilation
Degree of protection is obtained
Reliable avoidance of damage to electrical and electronic devices from
condensed water.
New from Hensel: Ventilation solutions
that prevent the formation of condensation!
Hensel solution:
Pressure compensation via combi climate glands
To adhere to the required degree of protection, the ventilation of the box is
done by installing a special combi climate gland.
Combi climate glands use an installed membrane to make sure that
compensation is made between the air in the interior of the box
and the ambient air.
This membrane prevents
ingress of humidity from outside.
As a result any condensed water
will dry over time as a result of the air
compensation or will dissipate. At the same
time the degree of protection for the box (up to IP
67) is obtained!
Combi climate glands allow additional entry
of cables without compromising the pressure
compensation.
