an energy saving of 45 to 65 percent of the
absorbed power. This does not even take into
consideration the additional savings from the
use of a one- to three-stage heat exchanger.
WHEN IS WHICH
BLOWER TYPE USED?
One-stage RT blower with emission regulation: Depending on the size, an RT vacuum
blower of 200 to 2,200 cubic meters/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, for
tissue applications, and, most importantly,
for replacing existing vacuum systems.
RC Type Vacuum Blower: Depending on
the size, the RC type vacuum blower can be
used from 180 to 2,800 cubic meters/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, paperboard, 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.
