GWS410 Organic Solvent Washing Unit



GWS410 is the world’s first water-based solvent neutralizer designed primarily for spray dryer.  It traps contaminants in solvents by using tap water or alkaline solution at atmospheric pressure and room temperature.

GWS410 is designed with a washing tank — when solvent vapor enters the tank, sprayed water adheres, cleans and neutralizes solvent particles, before returning to the bottom of the chamber.


  • Uses water or alkaline solution
  • Eliminates harsh solvents
  • Minimizes equipment rust and corrosion
  • Simple operation
  • Easy maintenance — only requires monitoring of water’s pH level in the storage tank and condition of molecular sieves
