DUE TO n-Propyl bromide now being included in Annex 14 of REACH

EnviroTech Europe Ltd (ETE) continue to publish it as historical information and to record changes occurring in legislation which have affected decisions on formulations and equipment used in vapour degreasing - the most effective, quickest, flexible and cheapest cleaning system used in industry.

EnSolv® invented and patented by EnviroTech has been a market leader all over the world for vapour degreasing. It is based on n-bromopropane (nPB) which now cannot be used as a vapour degreaser within the UK or EU without authorisation.

Archived information about EnSolv®  can be found using the Discontinued Products & Resources navigation menu on this page.

Using experience accumulated over 40 years supplying and supporting users of the vapour degreasing process ETE specialists have developed “drop in” alternatives:
ProSolv®, ProSolv5408e®  and EnSolv CC-A® give the same or improved level of performance and economy as the original EnSolv® products.

EnSolv CC-A

The preferred “drop in” substitute for Trichloroethylene and other chlorinated solvents used for oxygen cleaning

EnSolv® solvents have been used in the oxygen systems industry for many years to clean tubing, components, cylinders and any other parts that may come into contact with liquid or gaseous oxygen. Since its introduction in 1995, EnSolv® has remained the highest quality and most stable nPB solvent in the industry. While at one time 1,1,1-Trichloroethane, HCFC-141b or Freon were the standard cleaning agents for oxygen breathing systems, EnSolv® has since been proven to clean equally as well.

EnSolv® is recognized and used internationally as a preferred cleaning agent for oxygen systems by many of the leading compressed gas supply companies.

NASA has used EnSolv® to clean rocket boosters prior to filling them with highly reactive and explosive hydrogen peroxide fuel.

EnSolv® has been independently tested and found to conform to the SAE ARP1176 cleanliness level standards and is listed in the ‘Compressed Gas Association’s Directory of Cleaning Agents for Oxygen Service’.

EnSolv® conforms to SAE ARP1176 cleanliness level standards.

The original patented n-Propyl Bromide solvent for vapour degreasing

Since its introduction in 1995, EnSolv® vapour degreasing solvent has remained the highest quality and most stable nPB solvent in the industry. EnSolv  patented azeotropic formula provides for superior stability, acid neutralization, white metals reaction prevention, soil lifting and rust inhibition. In most vapor degreasing applications, the addition of extra stabilizer boosters is not required and process control maintenance is very painless.

EnSolv® is widely recognized as the premier general use stabilised n-propyl bromide (npb) solvent for a variety of applications including precision optics, electronic components, high vacuum components, oxygen systems and medical devices.
