Chlorinated hydrocarbons

Cleaning with chlorinated solvents counts as one of the classical procedures in industrial parts cleaning. Its success is based on the following characteristics:

Very good degreasing action
Low surface tension
Rapid parts drying
No flash point

To avoid risks to health and the environment, the use of chlorinated hydrocarbons is controlled by the 2nd Federal Immission Protection Ordinance (BImSchV). This dictates that cleaning must take place in an enclosed system which ensures that the extraction area is only then released when the solvent concentration is less than <1 gm per cubic centimetre of air.

With the integrated process air volume displacement (PLV), which is without any competition in the market, we provide a particularly efficient and environmentally friendly system for the completely exhaust-air-free operation of chlorinated hydrocarbon cleaning systems without activated carbon filter. It provides the user with various advantages:

Saving of operating costs
Low consumption of stabilisers for the solvent
No interruptions due to the system

The group of chlorinated hydrocarbons includes tetrachloroethylene, trichloroethylene and methylene chloride. In the hazardous materials directive trichloroethylene has been classified as carcinogenic since mid-2002 and must therefore be substituted for.

Thanks to their design for multi-stage processes – cleaning, rinsing, vapour degreasing and drying – they also are suitable for the tasks of fine and finest cleaning.
