1,1,1 Trichloroethane (TCA) Replacement

Entron Free Sample

EnTron Non-Flammable Critical Cleaning Solvent has almost exactly the same favorable physical characteristics, cleaning performance, and compatibility with metals, plastics and elastomers as 1,1,1 trichloroethane, without any of the negative effects on the environment associated 1,1,1 trichloroethane. Contact us today for a free sample.

EnTron is United States Environmental Protection Agency (USEPA) Significant New Alternatives Policy (SNAP) Program approved for solvent cleaning applications. Unlike 1,1,1 trichloroethane, EnTron has been reviewed by the USEPA SNAP program and EnTron has been determined to be acceptable to the environment for ozone depletion and global warming.

Seamless Change Over

Switching to EnTron from 1,1,1 trichloroethane in your vapor degreasing system is easy and seamless. The conversion to EnTron requires no equipment modifications, except minor adjustments to the temperature settings. EnTron and 1,1,1 trichloroethane boil at 160°F, therefore all of the standard control settings will match.

Easy to Dispose

Another advantage of switching from 1,1,1 trichloroethane to EnTron is waste disposal. EnTron is not a hazardous material, and as long as hazardous materials are not introduced into the waste stream, the generated waste can be disposed of as non-hazardous. We offer a free spent solvent disposal program in which all of our customers may participate.
