About VOC washer development - VOC gas reduction apparatus -

Several years ago, the company which sells the reduction apparatus of the system which makes VOC gas absorb with liquid existed.
But, there was almost no apparatus with which a long-term test and test data are recorded.
It's considered that the following contents are reasons.

The development of liquid which carries out stable absorption for a long period of time with safety is difficult
Liquid has a bad smell
Development of the mechanism in which VOC gas and absorption liquid are stabilized and it is made to contact is difficult

Absorption liquid

The absorption liquid of our company succeeded in development of the epoxy system absorption liquid which is safe and
excellent in absorbency by Negishiken (research institution of our company).
It can be tolerable to use of several years, and is very tough absorption liquid which absorbs mixed solvent gas satisfactorily. (The feature should look at a catalog)

Apparatus

Design development of apparatus spent long experiment time, and developed a structure suitable for absorption liquid.

An initial cost, a running cost, and a maintenance cost are cheap apparatus.
Those interested need to look at thing. (Our test factory)
