In 1947 Conrad Naber founded his family business and manufactured pottery kilns for private use with a few employees. He purposefully expanded the business and put the company on an international course. In the meantime, Nabertherm - based in Lilienthal/Bremen - designs and manufactures furnaces and heat treatment systems for a wide variety of industries and delivers the products all over the world.
