two years," says Dobler. Numerous conversion references evidence an energy savings
of 45-65 percent of the absorbed power. This
does not take into consideration the additional
savings from the use of a one- to three-stage
heat exchanger.
New tissue installations of TURBAIR systems include the following:
* SCA in Germany
* WEPA in Germany, France, and Poland
* FRIPA in Germany
* HAYAT in Turkey, Russia, and Egypt
* Ipek Kagit in Turkey
* Metsä Tissue in Poland
* First Quality Tissue in the US
* Sofidel in Poland and the US
TREND TOWARD VACUUM
SYSTEM RETROFITS
Paper manufacturers are increasingly retrofitting their production plants with one-stage
RT blowers; the old vacuum systems previously installed in existing tissue machines are
being replaced with the TURBAIR technology.
Model RT 56 is most popular for the narrow
2.8 m tissue machines with production speeds
of up to 2200 m/min, while the larger RT 71 is
the preferred model for 5.6 m tissue machines.

Which Blower Type
Should a Mill Use?
ONE-STAGE RT BLOWER WITH EMISSION REGULATION:
Depending on the size, an RT vacuum blower of 200 to 2200 m3/min and up to 60
kPA can be used. Thanks to the automatic outlet regulation, the volume flow adapts
flexibly to the relevant requirements of the paper machines. The controller automatically governs the volume requirement from 30 to 100 percent. At the same time, the
RT with a frequency-controlled drive can set the vacuum between 35 and 60 kPa.
This large area of application makes the RT range perfect for felt conditioning, tissue
applications and, most importantly, replacing existing vacuum systems.
MULTI-STAGE RC BLOWER:
Depending on the size, the RC type vacuum blower can be used from 180 to
2800 m3/min and up to 75 kPa. With its up to four intake manifolds, all vacuum levels
can be operated on the filter and press section. At the same time, the blower with a
frequency-controlled drive can set the vacuum between 55 and 75 kPa. It is chiefly
in demand for new installations for graphic papers, cardboard, or chemical pulp.
These require a high vacuum, which the RC type blower supplies reliably, thanks
to its multi-stage centrifugal design. It can replace entire water ring pump systems.
This technology covers all the usual manufacturing processes: conventional crescent former,
TAD (through-air drying), ATMOS (Advanced
Tissue Molding System) and Advantage NTT

technology for producing sanitary paper.
Figure 1 shows a few examples of how mills
are using TURBAIR technology to replace the
existing vacuum system.
