Since Co₂ simply dissipates into a gas after impact with the surface, it leaves only the contaminant as waste. Also Co₂ does not abrade the surface as does sandblasting or pressure washing, thus it can clean surfaces such as motor and generator windings. We specialize in detail vacuuming of industrial facilities. We serve a variety of industries with pressure washing. We have heated power washing units that provide unparallel cleaning. Additionally we have a wide range of units for the most demanding projects.
