Both the traditional and the new environment-friendly salt bath processes are firmly anchored in modern manufacturing technology. Durferrit has been a pioneer in this field for 75 years now.

Durferrit has been part of the HEF-Groupe since August 2001 and supplies under the name Durferrit GmbH about 450 different salts and peripherals for use in heat treating. The outstanding performance in this field has been recognized by international environment awards.

Durferrit also supplies plants for carrying out heat treatment and salt bath vulcanizing. In the design, and later operation, of these plants the protection of the environment plays a major role.

The heat treatment processes, plants and consumables constitute a unit. They can be obtained all over the world.

In 1994 work was intensified on the salt bath heat treatment of steel and non-ferrous metals and the large scale transfer of heat for the chemical industry and vulcanizing plants.

The roots, however, go back to the year 1925. At that time, as a department of Degussa AG, and later as an independent company, the company quickly enjoyed world acclamation.

For many decades we have been serving customers from the automotive industry and its sub-suppliers, aviation and aerospace, transmission and engine manufacturers, ball bearing and tool manufacturers, out-sourced heat treating facilities and companies in the chemical and rubber industries.
