Gord Montgomery of “The Monty Heat Treat News” was fortunate enough to be able to visit two German furnace builders this past week, one of which is family owned ROHDE Schutzgasöfen GmbH located in Hanau, Germany (near Frankfurt). The company was founded in 1979 and it is now a second generation firm with the current owners being Joern & Natasha Rohde. With roughly 30 employees we would consider this to be a mid sized furnace builder, one who specializes in retort style furnaces. One of their many claims to fame is the fact that just a few short years ago the company built what is one of the largest pit carburizing furnaces in Germany, a unit with working dimensions of 17′ X 17′ with a weight capacity of 50,000 pounds which is located at commercial heat treater “Reese” in Bochum, Germany.

In addition to their line of pit furnaces Rohde is also very well known for their Salt Recovery Units, a system designed to reclaim all the salt from wash tanks where the quenching medium is salt. Interestingly enough the company recently announced a partnership with a US furnace builder, McLaughlin Furnace Group of Avilla, Indiana.

These photos show a couple of the furnaces currently under construction.
