Vapour degreasing is the simplest but most effective industrial solvent cleaning process which, until recently, has been subject to little change since it was first invented in the early part of the 20th century. This is a very mature chemical technology, but legislation changes in recent years has impacted the industry significantly.

Chlorinated hydrocarbons have historically been the solvents of choice for vapour degreasingcompatible with most materials, stable in use, producing a nonflammable saturated vapour heavier than air at a temperature greater than ambient. Traditional solvents such as trichloroethylene exhibited all these characteristics but concerns about its carcinogenic properties and the danger to operators by exposure, led to a continuing search for a safer alternative. 1,1,1 trichloroethane based formulations became popular in the last century as a safer replacement. Although safer for users, it proved to be depleting the Ozone Layer and was subsequently banned. N-Propyl bromide (nPB) based formulations became popular in the last part of the century as a safer replacement, but this was later put in Annex 14 of REACH by the EU and can no longer be used as a vapour degreasing solvent in Europe. Countries around the world are now setting increasingly stringent environmental legislation to control emissions of Ozone Depleting and Global Warming industrial cleaning solvents. This has led to new chemical formulations being developed for industry.

Over 20 years of innovation for industry

EnviroTech Europe Ltd have been supplying vapour degreasing solvent formulations for over 20 years, constantly responding to regulatory requirements for environmental and safety laws and the need for improved standards. Staff and distributors are highly trained to work with customers to advise on the use of industrial cleaning solvents, helping them to navigate through legislative changes and ensure their vapour degreasing and cleaning solutions remain within regulatory boundaries.

Customers may have recently read in the industry press about another major industrial supplier ceasing production of their range of fluorocarbon containing metal degreasing and vapour degreasing solvents. They may be concerned that other major suppliers will follow suit. Envirotech Europe would like to assure the industry of its intention to continue the manufacture of its ProSolv® range of metal cleaning and vapour degreasing solvents for the foreseeable future.
