EnSolv is the non-flammable solvent designed as a direct replacement for 1, 1, 1-Trichloroethane, HCFC 14 fb as well as other CFC and HCFC based chemicals used for vapor degreasing. EnSoZv’s physical properties closely match those of l,l,l-Trichloroethane. EnSoZv is comparable to or out-performed l,l, 1-Trichloroethane in most cleaning applications including precision vapor degreasing, ultrasonic cleaning, cold hand wipe, and flush cleaning applications.

EnSoZv can be used in most vapor degreasers and ultrasonic cleaning machines. Simply clean and neutralize your existing vapor degreaser, adjust the heater and cooling coil thermostat controls, add EnSoZv and you’re back in business. There is no rinsing or further cleaning required after the target material is removed from the degreaser.

EnSoZv possesses excellent cleaning properties, solvency power, and soil loading capacity for a wide range of material including solder fluxes, waxes, adhesives, metal working lubricants, anti-seize compounds, resins, and oils. EnSoZv’s evaporative rate is moderately fast and leaves behind no measurable residue after cleaning.
