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.
