operates so effectively that CO 2
, nitrogen, carbon monoxide
and carbon emissions are significantly lowered. At the same
time, an innovative burner system and highly efficient
heat exchangers ensure a greatly reduced gas consumption.
However, the greatest energy saving for Volkswagen is from
recycling the waste heat back into the process.
The E-Shuttle makes it possible to optimise the quality
of pretreatment and cathodic dip coating by sequences of
movement adapted individually to the body shape.
The new Volkswagen plant in Chattanooga was constructed
on a site covering 560 hectares. It is one of the world’s most
modern and most environment-friendly automobile plants.
paint shop Meets solar heating
technology
With the Ritter XL Solar company, Eisenmann has found a
strategic partner for a completely new business model: largescale
plants for the paint shop combined with solar heating
technology. This method features high CO 2
savings and an
economically attractive overall yield. It uses vacuum tube
In Central Europe it is possible to replace
up to 32 per cent of conventionally produced
energy for pretreatment with a solar heating
plant with a size of 3,000 square metres.

collectors installed on the roof of the production plants. The
heat produced by the solar collectors is passed to a hot water
storage tank from which the various consumption points
are supplied. The energy obtained can also be used to cool
specific processes. Using solar heating energy, it is possible
to cover between 30 and 50 per cent of the annual process
heat demand of a paint shop, and also reduce CO 2
emissions
accordingly depending on location and operation.
Waste-to-energy: biogas plants
Eisenmann research covers not only how energy can
be generated cleanly in large-scale plants, but also how
waste can be used for energy production. Garbage as an
energy source is nothing new in itself. In Germany, waste
cooking fat has been used to produce biodiesel since as
early as the 1990s. Eisenmann offers a number of processes
for environmentally-friendly disposal of waste, waste
gases and waste water for industry but also for energy
utilities and municipalities. Eisenmann’s Environmental
Technology Division has been marketing biogas plants
since 2003. Over 90 of these plants are now in operation.
By fermenting various substrates – biowaste, grass, bush
and tree cuttings, liquid manure or solid manure – the
plants produce biogas which is then converted to electrical
power and heat. Sustainably-grown raw materials are also
suitable as substrates; however, this is increasingly viewed as
inappropriate owing to the area it would take up in Europe.
Eisenmann also offers its customers a number of special
solutions, besides the classic biogas plant.
oxidation furnaces for carbon
fibre production
What weighs less also consumes less energy, and thus
produces less CO 2
. Carbon fibre has excellent mechanical
properties where it is used as a composite material. But the
material of the 21st century has a positive aspect for the
CO 2
balance with its low weight. By now, not only have
the aerospace industry, motor racing and sports equipment
sectors discovered this but also the automobile industry. In
electric automobile manufacture, the lightweight material
which can compensate for the weight of the battery is a
crucial factor for market feasibility. Eisenmann offers a
complete production line for manufacturing carbon fibres.
The successful launch into the carbon fibre production
sector and the numerous innovative products and solutions
from Eisenmann are essentially based on the company’s
plant engineering expertise and its many years of research
and development activities. This, together with a modern
technology centre at the German headquarters, allow further
development of CO 2
-saving engineering for green production.
