ProSolv®5408e is a high-performance solvent cleaner used for sustainable and future proof vapour degreasing. Soft on the environment and safe for users, it offers improved cleaning at lower costs. Low boiling point, economical with energy with low solvent losses, faster production.
Innovation driven by legislation
Vapour degreasing, with or with-out ultrasonics, is the oldest, simplest and most effective solvent degreasing and metal cleaning process used today. It has, until recently, been subject to little change since it was first invented in the early part of the last century. In the UK, Europe, United States and other advanced industrialized economies increasingly stringent legislation to control emissions of VOCs, Global Warming Compounds, Ozone Depleting Compounds, and those compounds associated with human health concerns has led to new formulations for precision cleaning solvents.
Halogenated hydrocarbons are the solvents of choice for vapour degreasing and cleaning. The process is essentially simple. A tank with a sump to contain the solvent, heaters at the base and condensation coils around the top section to control the height of the vapour is all that is needed. When heated in the sump halogenated solvents produce, in most cases, a saturated vapour between 3 and 4 times heavier than air at a temperature greater than the ambient temperature of the parts to be cleaned. This allows the solvent vapour to condense on the surface of the parts. The condensate dissolves the contaminants such as oil, greases, flux, and soils returning the used solvent into the sump of the machine for recycling into vapour which continuously condenses onto the parts until they have achieved vapour temperature when, with no further condensation, the process is complete. Parts removed from the cleaning machines are very clean, warm and dry.
The most common halogenated solvents, in use for commercial purposes, are non-flammable so present no risk in this process. Perchloroethylene, used mainly for dry cleaning, methylene chloride previously used widely in paint strippers, 1,1,1- trichloroethane and trichloroethylene used for vapour degreasing were the original materials used based on chlorine chemistry. However continuing concern about the environmental impact and danger to operators by exposure to chlorine-based solvents, especially trichloroethylene, has led to a continuing search for safer alternatives, such as ProSolv®5408e, a trans-1,2-Dichloroethylene based solvent mixture that is non-flammable. The ProSolv®5408e vapour degreasing process gives the highest levels of economical cleaning with minimum energy usage, low footprint on the factory floor, safety for the operator, and high production rates with low solvent usage or environmental impact. With the new generation of sealed cleaning machines its future as the process of choice is assured.
