HNO3+HF Scrubber pickling on stainless steel wiresHorizontal scrubbers are used when size or space availability is of concern. They are very compact, yet all parts are easily accessible and therefore can be installed in confined spaces where there is insufficient headroom for a vertical tower.

Efficiency is generally equivalent to that of a vertical scrubber. Its simple design allows several scrubbers to be connected in series to form a multi-stage scrubber, which is particularly effective for deodorizing and NOx abatement. Its box shape can easily be adapted to customer space requirements and enable installation in areas that were not initially planned for vertical scrubbers.
