EnSolv is the perfect direct replacement for TCE, Perchloroethylene, 1,1,1-Trichloroethane and other hazardous vapor degreasing and general use solvents for critical applications such as oxygen service, precision optics, medical devices, high vacuum components and electronics. EnSolv is a superior cleaner for oxygen service lines and components that leaves virtually no residue and conforms to SAE ARP1176. It is an excellent choice for removal of a wide range of organic soils by vapor degreaser, ultrasonic cavitation, dip tank, flushing or hand wiping. EnSolv is a patented azeotropic mixture that can be distilled and reused through numerous cycles before it needs to be replaced. Although Enviro Tech offers stabilizer booster in 5-gallon pails, the synergistic action of EnSolv’s patented stabilizer package typically precludes the need to ever add stabilizers to maintain the integrity of the solvent through normal use.
MATERIALS COMPATIBILITY
EnSolv is compatible with all metals and many plastics and other materials typically cleaned in vapor degreasers, ultrasonic tanks or manually. For a full list of compatibility recommendations, refer to the “Materials Compatibility” document. Any materials not listed in this document should be tested for compatibility in the conditions of use.
HEALTH & SAFETY
EnSolv is a non-flammable, non-carcinogenic solvent mixture that is safe to use in many applications. Enviro Tech recommends that safe work practices are implemented whenever handling chemicals of any kind to minimize exposure levels and prevent toxic effects. Please refer to the EnSolv Material Safety Data Sheet for more specific information on workplace exposure levels, toxicity and personal safety recommendations.
REGULATORY INFORMATION
EnSolv is classified as non-hazardous for transport by the U.S. DOT. For international shipments, EnSolv is exempt from classification as a flammable material per Special Provision A3 under Sub Section 4.4 in the IATA shipping manual. Spent EnSolv is classified as a non-hazardous waste unless RCRA hazardous contaminants are deposited into the material through a cleaning process. The principal component of EnSolv, n-Propyl Bromide, is currently classified as 100% Volatile Organic Compound (VOC). Enviro Tech has petitioned the U.S. EPA for VOC exempt status based on low atmospheric reactivity derived from independent testing. The U.S. EPA has recommended in June 2003 that n-Propyl Bromide be approved under the Significant New Alternatives Policy (SNAP) as a suitable replacement for ozone depleting chemicals. N-Propyl Bromide has been shown to neither deplete the ozone layer nor contribute significantly to global warming.
PROCESS CONTROLS & MAINTENANCE
Prior to charging a piece of equipment with EnSolv, the equipment should be thoroughly cleaned and neutralized according to the procedure listed in the “Preparing Equipment to Switch to EnSolv” document. After the equipment is up and running with EnSolv, the acid acceptance levels of the solvent should be monitored on a regular basis with an Acid Acceptance Test Kit, available from Enviro Tech. EnSolv can be distilled and reused through numerous cycles before losing its capacity to neutralize acid residues. If acid acceptance levels ever reach 29 drops or greater
VAPOR DEGREASER SETTINGS
The following are recommended settings for temperature and safety sensors on a typical vapor degreaser. Certain features are optional and may not be present on a particular piece of equipment.
