The eltherm GmbH –
Solutions with electrical heat tracing systems
eltherm GmbH is an international operating company specialising in the field of electrical heat tracing systems. With more
than 40 years of technology know-how, continuous demand
for the highest quality and flexibility, this company has grown
significantly since its humble beginning. A clear commitment
to the production site in Germany strongly emphasizes the
philosophy of eltherm, which is to supply its customers with
electrical heat tracing system solutions individually customized to their requirements of the highest level.
Handicraft: the eltherm-manufactured heating cables are sewed
together with the according insulation custom-fit to the backing fabric
of the heating jackets and mats.
With its own comprehensive production facilities for all
types of heating cable and accessories eltherm has built up the
engineering expertise to become one of the leading manufacturers of electrical heat tracing systems in the world.
Besides frost protection and temperature maintenance
applications up to 1000 °C, eltherm is the competent partner
for complete system solutions like heating whole chemical or
other industrial plants.
eltherm proved its potential and expertise in different applications for industries such as oil and gas, power plant, construction, automotive and food industries.
The eltherm engineers would like to face your challenge also.

Solutions for your challenge!
Qualified Solutions
eltherm has its own production facilities and its own
research and development team. This is where innovative
solutions are born and where products are constantly
improved to meet market requirements. Our qualitymanagement system ensures that only top quality and fully
functional products leave our factory.
Apart from EAC certification and VDE guidelines, for
instance, eltherm also meets the strict requirements of the
ATEX certification. In addition, eltherm has had ISO 9001
certification for many years. For 2011 the certification according to ISO 14001 will be completed.
Flexible Heating mats and jackets
Flexible heating mats and jackets provide optimum heat
transfer with good heat distribution. Heating mats are the
ideal solution for simple level surfaces. They can also be manufactured separately from the insulation upon request.
Heating jackets are used when uniform heating of surfaces
with more than two levels is required. Very flexible thanks to
custom-made segments, they can be produced to match
almost any shape. Heating jackets are easy to apply and
remove with integrated heat insulation, which considerably
reduces the installation and maintenance overhead.
eltherm® heating mats and jackets are used in an extensive
range of applications such as for heating bunker tips, IBCs,
fans, pumps and many more. Flexible heating mats and jackets are also indispensable in research and development as
well as nuclear technology.

Layout of heating mats / heating jackets:
Heating mats and jackets consist of textile materials which
cling closely to the object being heated. To ensure a long
service life, only high-grade materials are used. The selection
of the material to be used depends on the conditions of usage.
Criteria include the operating temperature and location of
the application.
Heating jackets with a metal outer jacket can be used
depending on the application, for example if high durability is required due to excessive load conditions. They are
especially robust due to their design. Hinges and adjustable
clamp fasteners are used to compensate for tolerances in
the external diameter.
Aluminium-coated glass fabric is used for surface temperatures up to 160 °C, while plastic fabrics are used for temperatures
up to 80 °C. Textile glass is used up to 450 °C, while quartz is
used for surface temperatures up to 900 °C. Eyelets, hooks and
Velcro fasteners are used for fastening.
Depending on the specification, our heating mats and jackets
can also be manufactured for use in hazardous locations.

Suitable Measurement and Control
Electronic Temperature Controller, Type ELTC/H-14
The ELTC/H-14 is an electronic temperature controller with digital display for wall mounting. The temperature is measured by a Pt 100 sensor,
processed by the microcontroller and displayed. After having evaluated the actual and preset values, the appropriate output relays are switched,
depending on the configuration.
The controller is equipped with a socket. The unit is supplied in a weather proof plastic enclosure, with a transparent cover.
