The result of over 35 years research and development, a Seibu
Giken Rotor inside ensures outstanding performance. Rely on it.
Seibu Giken introduced the silica gel rotor and continues to be
the leading supplier of silica gel type rotors worldwide.
Rotor Construction: Truly unique in concept and design
Non-respirable ceramic fibers with an aspect ratio of length to
diameter of over 100 to 1 are formed into sheets which become the
substrate for the finished rotor. Corrugated sheets are formed into
an optimized fold size. The corrugated sheets are then interleafed
in a winding operation to produce the rotor. Organic binders used
in the forming process are removed by a calcination process of heating
the rotor substrate to a very hot temperature. This process causes
thermal disassociation of the organic compounds leaving only the
ceramic in a rigid structure, thus ensuring that the rotor will
be extremely stable under even the highest reactivation temperatures.
There is a significant safety factor between the recommended maximum
reactivation temperature and the maximum temperature the rotor can
withstand without damage. The rotor substrate is cut into pie shapes
and further treated in preparation of incorporating the desiccant.
The final treatment of the SSCR rotor includes a grinding process
using diamond tip grinders to produce a smooth and flat surface
finish. This finishing operation is unique within the industry and
provides for a long seal life.
SSCR rotors are non-shedding. The formation of the desiccant "in
the flute" for the SSCR-M and Ultra rotors is a unique patented
process held only by Seibu Giken. This process results in the encapsulation
of the ceramic substrate by the desiccant. Only the desiccant is
exposed to the air to be dehumidified, not the substrate.
This graphic shows
the rotor substrate at a 240 magnification before and after the
desiccant is applied to the ceramic. The final product is also shown
at a magnification of 2,000,000X. Notice that there are no desiccant
voids or gaps. No fibers are exposed through the desiccant.
The desiccant for SSCR-M and the SSCR Ultra rotor is a metal silicate
with advanced chemical formulation to achieve a higher number of
adsorption sites per unit area than standard silica gel. The desiccant
is actually made "in the flute" not dipped or glued into
the substrate. The result is that the ceramic fiber provides the
support for the desiccant to form onto. The combination of this
support and the shape of the flute provides for adsorption and reactivation
from the surface of the flute. Further, this construction eliminates
attrition experienced by bulk desiccants, due to thermal stress
and fracture due to high velocity.
SSCR-M Rotor: The industry standard.
- SSCR ceramic substrate and metal silicate desiccant for outstanding
performance.
- The highest water removal capacity per volume ratio among silica
gel rotors.
- High heat resistance, high strength
 SSCR
Ultra Rotor: The new generation in rotor performance.
- SSCR ceramic substrate with advanced metal silicate chemistry.
- More adsorption sites per unit area then even the SSCR-M rotor.
- Requires less reactivation energy per pound of water removal.
- Consumes less energy for the same performance as the SSCR-M
rotor.
- Lower heat capacity resulting in greater energy transfered into
the desiccant and less into the substrate during reactivation.
 SSCR-Z
Rotor: The choice for low dew point performance.
- Capable of producing discharge air dew point temperatures of
minus 100 °F.
- Utilize molecular sieve as the desiccant and the same ceramic
substrate as the SSCR-M and Ultra rotors.
- Molecular sieve desiccant is bonded to the ceramic substrate
by high temperature fusion of a colloidal silica mixture. Result:
the molecular sieve is fused in place and can not separate from
the ceramic substrate.
Rotor Features:
Extremely stable under even the highest reactivation temperatures.
SSCR-M, Ultra and Z rotors are available in many sizes including
thickness of 2, 4, 8 and 16 inch with a range of diameters from
7 to 166 inches for up to 50,000 Scfm.
Life cycle: 10-15 years with proper filter selection and maintenance.
Rotors are washable - the first of their kind when introduced in
1987. Test rotors have been subjected to 27 washings in a 100,000
hour accelerated life cycle testing with a result of less than a
10% change in performance.
