Critical Cleaning Solvent

high performance vapour degreasing solvent, simple “drop-in” replacement for n-Propyl bromide and trichloroethylene

ProSolv® vapour degreasing solvent is a proprietary tertiary azeotropic formulation developed as a direct “drop In” replacement for n-propyl bromide, trichloroethylene and other chlorinated solvents.

ProSolv® is extremely stable and simple to use meeting all the increasingly stringent legislative demands for safer, non flammable solvents with a low environmental impact in the precision engineering industries.

Precision metal cleaning

ProSolv® Trichloroethylene replacement can be used in most existing vapour degreasing equipment and can be used safely for immersion cleaning using ultrasonics, where it has been optimised with a high specific gravity and very low surface tension.

Unlike other chlorinated solvents ProSolv® can be used for manual cleaning in a suitably ventilated area. Typical applications are where high performance critical cleaning is required at lower cost than other fluorinated solvent cleaners. Vapour degreasing for medical, aerospace, optics, oxygen equipment service, high vacuum components and electronics.

ProSolv® is an excellent choice to replace flammable solvents such as MEK, Acetone, Iso propyl alcohol (IPA) or hydrocarbons where manual wiping or brush cleaning is the preferred cleaning method.

ProSolv® is a stable azeotrope which can be recycled by distillation for reuse through many cycles. It is a very stable mixture with no need for monitoring or the need for additives or stabilisers.

ProSolv® offers a cost effective Trichloroethylene replacement in formulations for dip, spray or aerosol applications and as a fast drying carrier solvent for oil, silicones and other

How does vapour degreasing work? Improvements in equipment technology, driven by legislation

Vapour degreasing is the simplest but most effective degreasing and cleaning process. It has, until recently, been subject to little change since it was first invented in the early part of the last century. The name for the process is a misnomer as the cleaning is actually achieved by solvent vapour condensing on the cooler target parts the hot liquid solvent dissolving oil and removing dirt.

Vapour degreasing is a mature technology on which legislation is now effecting changes so fundamental that the more accurate name for the process “Condensation Cleaning” should be used to reflect the way in which it works. More importantly the alternatives in equipment design and fundamental differences in the technologies which guarantee its continuing use in the future need to be considered and understood.
