Area of business:
Development of complete solutions
for pipeline and plant construction,
tank cleaning, instrumentation and
control engineering and cleaning
technology
Reliable control of the pneumatics is provided
by VTSA and MPA with fieldbus.
The vessels are locked using a special device consisting of a coupling with spring
package, stainless steel cylinder CRHD and one-way flow control valve CRGRLA.
“Corrosion-resistant components made
from high-quality stainless steel increase
the operational reliability and availability
of our cleaning systems.”
Dr. Ing. Klaus Roos, Head of Cleaning Technology, ROTAN GmbH
is adjusted via the corrosion-resistant
one-way flow control valve CRGRLA. The
process ends when the cleaned vessels
are transferred to the buffer station.
Simultaneous movement
Inflatable seals keep the doors of the
inner chamber sealed during cleaning.
The doors are opened and closed by two
linear pneumatic cylinders. Both cylinders
must open and close simultaneously
to avoid potential misalignment of the
doors. To achieve this, it was essential to
ensure that the pneumatic tubing above
the valves are exactly the same length.
The closing and opening speed of the
doors is regulated by one-way flow
control valves which are actuated using
individual valves.
Long service life
When equipping the ROTAN cleaning
system with Festo components, corrosion
resistance was of central importance.
Among the components used were the
stainless steel standard cylinder CRHD,
the stainless steel piston-rod attachment
CRSG and the stainless steel Quick Star
connector CRQS. The combination of easy-
to-clean design and total operational
reliability increases system availability
and reduces downtimes.
