Industrial Desiccant Dehumidifier

Industrial Desiccant Dehumidifier

There is moisture everywhere. Damp air in the wrong place can damage products and building or reduce the efficiency of a production process.

When excess moisture is trapped indoors, it causes mold and bacteria growth, metal corrosion and damages to costly electronic and electrical components. Damp air in the wrong place can be damage your products and anything in your store. A dehumidifier is your best means of avoiding such harmful moisture damage.

All DST desiccant dehumidifiers use the Seibu Giken Silica Gen Rotor. In the Seibu Giken rotor the silica gen is chemically bonded to the structure, which means that thee is no desiccant carry0over to the air. It also means an excellent lifetime. After 10 years of operation the Seibu Giken rotor retains more than 90% of its original capacity. Another important feature is that the Seibu Giken rotor can be washed if it becomes contiminated. This is especially important for rotor working under harsh condirions.

Seibu Giken was the first company to develop a silica gel rotor and is still the technology leader. Tests carried out by the well-known Frauenhofer Institute show that no dust is carried over the dry air in a Seibu Giken rotor. Tests on DST dehumidifiers placed in sewage stations have also shown that the rotor is bacteriostatic.

The adsorption rotor is manufactured from alternate layers of flat and corrugated sheets, impregnated with an active component called desiccant. It is made to form a vast number of axial air channels running parrallel through the structure. As the air passes through the channels it is dried. The rotor is the most important part of the air dehumidifier. It is the rotor determines the capacity and lifetime of the unit. Hence you want a dependable, stable and efficient rotor.

The D-MAX Rotor. D-Max is the next generation of silica gel rotors from Seibu Giken and is a development from the SSCR-U. The silica gel is still chemically bonded to the structure, which means that there is no desiccant carry-over to the air and this also gives an excellent lifetime. The D-Max rotor can be washed if it becomes contiminated. A new feature with the D-Max rotor is that is bacteriostatic and fungistatic which means there will be no growth of bacteria or fungus on a D-Max rotor.

DST’s dehumidifiers are desiccant. The basic principle is that the air to be dehumidified is passed through the rotating rotor which adsorbs moisture. The moisture in the rotor is removed by a hot air stream.

Desiccant rotor principle

The Consorb

DST dehumidifiers dry air by passing it through a unique slowly rotating Seibu Giken desiccant wheel which extracts and retain the water vapor within its honeycomb structure.

The wheels move into a separate sector where fresh air is drawn into the system, heated and forced through the rotor section holding the moisture. This releases the water vapor within the rotor which expelled to ambient. No condensation forms within the rotor greatly reducing the possibility of microbial activity taking place.

Seibu Giken DST rotors are bactericidal, hygienic and high adsorption capacity. Some models are designed with internal heat recovery, 100% silicon free or with zeolite rotor for 1000 dew points.


Recursorb R

Recursorb R operates using integrated heat recycling. During the rotor’s regeneration (green), heat is absorbed , and then recycled in the purge-zone where incoming air is pre-heated and partly dehumidified. Energy consumption falls and the dry air becomes both drier and cooler compared to other sorption dehumidifiers.
