Salt Bath Technology

Our Salt Bath Technology uses salt melts, ranging from temperatures of 150 and 1300 degrees centigrade. The properties of salt melts are used to transfer heat in chemical reactors in rubber/chemical industries.

Salt melts are used to remove moulding sand, scale, glass and lacquers from parts and is known as thermochemical cleaning. The chemical and thermal actions are also used in improving the properties of materials in the heat treating of nonferrous (NE) / ferrous (Fe).

Test Heat Treating Plant

Environmental concerns have give new views on salt bath technology. We developed effluent-free salt bath heat treating sytems and have enjoyed considerable success over the last 10 years. The system means you can reduce liquid waste to zero and minimize water use utilising cascade techniques.

After the components are treated they are rinsed with a cascade method using very little water, saving you valuable cost and resources. This method is always proferred for new heat treating establishments.

Our waste air cleaning plants will remove salt fumes above the baths conforming to German Regulations protecting workers. Durferrit are specialists in solving your heat treating problems and we have a long history in the process.
