2. Overview


Basic process of SOLVENTCLEAN™

Process Zone

①VOC adsorption
The VOC laden air is cleaned as VOCs are adsorbed by the zeolite media as it passes through the rotor.

Desorption Zone

②VOC desorption and rotor desorption
The rotor, which has adsorbed VOCs, is moved into the desorption zone as it is rotated, and the VOCs are desorbed and concentrated by hot air (180 – 200°C). The concentration ratio can be between 3 to 30 times.

Cooling Zone

③Rotor cooling and heat desorption
In order to recover the adsorption capacity of the media after it has been exposed to hot air inside the desorption zone; the media enters the cooling zone where it is cooled down by process air or fresh air. Simultaneously, the cooling air recovers heat energy as it passes through the rotor. This heated air is then used for desorption resulting in an energy efficient system.


  • 1

    Low operating cost

    SOLVENTCLEAN is optimal for a large airflow volume with a low concentration of exhaust gas removal, and can reduce the operation cost for entire system.

  • 2

    High VOC removal efficiency

    99% VOC removal efficiency can be achieved.

  • 3

    High concentration ratio

    VOC concentration ratio between 3 to 30 times is possible. (Normally the concentration limit is 25% of LEL [lower explosion limit].)

  • 4

    Low pressure loss

    Honeycomb-structured adsorbent allows for low pressure loss and removal of large volumes of VOC exhaust gas while minimizing the operation power usded for the process fan.

  • 5

    Continuous removal of VOCs

    By using continuous desoprtion, the removal efficiency of SOLVENTCLEAN is more stable than that of raditional batch type concentration.

  • 6

    Removal of VOCs with high boiling points

    As an option, SOLVENTCLEAN can be equipped with a high temperature desorption system which can remove the solvents with up to 300 ℃ boiling point accumulated in the rotor.

  • 7


    100% of the materials used to construct the rotor are inorganic and non-flammable .

  • 8

    Low maintenance

    Simple construction of the rotor allows easy maintenance.
