In 1908 Kemna Bau presented a further development of the compound system: a superheated steam plow locomotive with overpowered steam and two high-pressure cylinders.

At the beginning of the 20th century, Julius Kemna became the "leading steam plow company on the
European continent and entered the monopoly of English companies on the world market". The company developed into a "large industrial enterprise" around the turn of the century. Due to capacity expansions

steam technology with compound or composite design, capable of significantly higher outputs with less consumption of heating material and water. With a keen sense for future developments, Kemna had recognized that the steam engine was not only revolutionary for industry, but also in
