Jet Mixers
The IKA ROTOTRON® RT is an all-purpose jet-flow agitator used for
homogenizing, dispersing, suspending, emulsifying, aerating, dissolving
and improvement of heat transfer. The RT is most effectively used for
tasks ranging between that of a conventional stirring machine and a
dispersing machine with a rotor-stator system.
Different diameters and bending angles of the stator tube, at inlet and
outlet, create optimal suctioning and a vertical flow direction. Even in
working vessels with unfavorable dimensions and shapes, an intensive
circulation is created. High rotor speeds and minimal distances between
mixing wings and the jet tube prevent back flow losses and guarantee an
intensive dispersion. Deflectors on the stator prevent air entry into
the medium at various immersion depths.
A standard propeller stirrer will disseminate energy throughout the
entire vessel content. A higher energy density can be achieved with the
use of a jet flow agitator and a flow-restricting guiding tube.
The jet-flow agitator ROTOTRON® is considered a uniquely
energy-efficient machine because of the substantial circulation and
mixing effect provided by the relatively small motor.
The ROTOTRON® RT is suitable for vertical and also submerged mounting
into large vessels. It makes unnecessary the use of conventional
agitators with extremely long shafts.
The RT machines mix media with a viscosity of up to 15.000 mPas. For
higher viscosities, flow direction reversing switch is recommended.
IKA produces the ROTOTRON® stirrers in six standard sizes for vessels
with volumes from 200 to 30.000 liters. All models are available with
two different types of flanges for installation in open or closed
vessels.
The ROTOTRON® for open vessels is available with floor, wall or mobile stands.
The rotating shaft is sealed with either a lip seal or a single-acting
mechanical seal. The ROTOTRON® is equipped with a mechanical seal for
operations under pressures of up to 10 bar or when processing abrasive
media.
The description of the RT machine contains the following information:
Type of machine
Size of the machine (diameter of the guiding tube)
Type of seal
Type of flange
Example: The RT 150-KT/KD is a ROTOTRON® RT with a 150 mm diameter
guiding tube, a lip seal and a KD flange for installation in closed
vessels.
