Description
Covering oils provide different functions when used in wave-soldering machines. Firstly, they protect the metal alloys from oxidation, which prevents the formation of oxide layers around the solder wave. Secondly, they provide a lubricating effect on the pump shaft. During the development of the covering oil EO-COVERFLUID TESU, Emil Otto focused on a good thermal stability and an optimum evaporation rate. Rigid deposits can thus be avoided. Compared to products containing waxes or mineral oil-based oils, the use of EO-COVERFLUID TESU can ensure very long oil lives. It reduces the maintenance and repair efforts of wave-soldering machines to a minimum.
