ROTOR types

ULTRA SSCR rotor
Only Seibu Giken DST desiccant dehumidifiers are equipped with the original SSCR rotor as standard. This SSCR rotor type was launched on the world market in 1985 by the Japanese rotor manufacturer Seibu Giken as the very first silica gel drying rotor. Since then, this rotor technology has undergone continuous further development. Discover the advantages:
- High adsorption capacity
- Long service life
- without desiccant discharge
- resists air with saturated moisture
- washable
- bacteriostatic
- non-respirable and non-toxic
- non-corrosive
- non-flammable
D-MAX sorption rotor
The new D-MAX sets another milestone in terms of even more optimized dehumidification performance and energy efficiency, worldwide.
The D-Max technology has been used in all our sorption dehumidification systems since September 2014. Chemists and product development engineers have tuned the already high-performance SSCR-U rotor from Seibu Giken even further.
The new D-MAX with 10-15% more power.

SSCR-H rotor
Bacteriostatic and hygienic design sets new standards in the pharmaceutical and food industries. The SSCR-H rotor is impregnated with a silver component after the actual production process. This active silver component destroys the cell walls of any germs on the rotor surface. The SSCR-H adsorption rotors have the following properties:
- Germicidal rotor surface
- High adsorption capacity
- Long service life
- without desiccant discharge
- resists air with saturated moisture
- non-respirable and non-toxic
- non-corrosive
- non-flammable

SSCR-CI Rotor
The SSCR-CI dehumidification rotor is an adsorption rotor that has been specially developed for the automotive industry. All components of the rotor are absolutely silicone-free. Discover the advantages:
- free from silicone
- High adsorption capacity
- Long service life
- without desiccant discharge
- resists air with saturated moisture
- washable
- bacteriostatic
- non-respirable and non-toxic
- non-corrosive
- non-flammable
SZCR rotor
The SZCR rotor with molecular sieve is used when a residual moisture content of less than -50 °C dew point is required for larger dehumidification systems. The SZCR adsorption rotors have the following properties:
- lowest dew points achievable
- Long service life
- without desiccant discharge
- resists air with saturated moisture
- bacteriostatic
- non-respirable and non-toxic
- non-corrosive
- non-flammable
