Dryers are one of the key components
match the entire machine system and
substrate used to ensure the desired
result and the expected quality of the end
product. When it comes to designing an
optimum drying process, it is not only
the air guidance concept but also the
right nozzle selection that is of decisive
importance for the coating result.
Polytype Converting � the company
headquarters in Hamburg, Germany, and
Fribourg, Switzerland � has decades of
experience in coating plant construction and
has already developed numerous concepts
the respective requirements for all types
of coatings. "The combination of nozzle
type and the adaptation of air speeds,
run properties enable us to control the
production factors in a targeted manner,"
emphasises Ronald Haunholter, sales and
marketing manager of the company, in
an interview with C2. "This enables us to
achieve an optimum mix of productivity,
Polytype Converting offers its customers a
technological solution that optimally meets
the requirements for controlling the drying
and production process in a wide range of
applications. The combination of guide roller
and air nozzle has established itself and is
used in particular for materials that tend

Previously, the system was used exclusively
aluminium coating and drying were reserved
for the classic driven guide roller dryers and

Polytype Converting has now extended
coatings on aluminium in temperature
and roller surfaces were used. "In the most
recently delivered machine installation,
drying with separate air guidance and
a very short zone division," continues
Haunholter. "This achieves a very high
solvent evaporation performance. Combined
than with conventional processes."

system thus makes an ideal contribution to product

C2: Polytype Converting's new slogan is "coating technology
for inspiring performance". What exactly does this mean?
Through our passion for constantly evol
ving technologies, we want to bring the spark of inspiration
to our customers so that they receive optimal support to
discussing energy recovery, solvent recycling and energy
balance optimisation. What solutions can we offer on these
key issues? Well, our dryers are constantly evolving in terms
highest possible proportion of circulating air in the circulating
air system in order to keep the proportion of fresh air to
be heated as low as possible. In addition, we are working
on further optimisations in the area of heating media, such
as gas, in order to achieve a better degree of utilisation. In
addition, we work closely with the manufacturers of the
peripheral equipment, e.g. solvent recycling systems, in order
to provide our customers with an optimum overall concept.PSA Technology GmbH

C2: Polytype Converting has been a joint venture of
What conclusions do you draw after two years?
We ourselves were surprised by the
dynamism with which the company has relaunched. There
founded we have seamlessly received a large number of orders
from a wide variety of market segments. The experience of our
colleagues from Switzerland and Germany probably played a
decisive role in this. This is why there were none of the usual
"teething troubles" that many mergers have to contend with.
The decision to operate the joint venture under the
Polytype Converting brand proved to be the right one. The
on the part of Jagenberg is excellent and represents an
important component of our successful development over the
past two years. We were able to gain a large number of new
employees at both locations. We have succeeded in attracting
a great mix of young employees and experienced industry
fact that the new premises, which we moved into after the
merger, are already reaching the limits of their capacities.
