Scrubbers

Scrubbers

We have the ability to produce simple to more complex scrubbers based on our client’s need. Our standard scrubber is comprised of a submerged plenum, which allows fumes to bubble through a water bath. We also have the ability to design automated systems which will monitor scrubbed air and automation for maintaining a neutral PH system. 

  • Used in applications where fumes or odor are problematic
  • Hydrochloric acid, acetic acid and ammonium based products to eliminate toxic fumes 
  • Ferric Chloride to address environmental issues
  • There are many other chemicals this product could be used for.
  • Very cost effective compared to other alternatives.
