The ever stringent pollution standards which limit the kind of solvents to be used and the difficulties of disposing of the spent material has urged heating element manufacturers to find an alternative to the chlorinated solvents used for degreasing the coils after winding.
CSM has put together a water-based system to achieve this. The main problem with the winding of coils was the use of mineral oils to help wrapping the wire around the mandrel. This was solved by using a special lubricant where the main components are soap and a very small amount of a vegetal oil. This lubricant is water soluble and biodegradable.
