The story
Martin Bitzer founded what would later become Bitzer in 1934 as Apparatebau für Kältetechnik. The company started out by manufacturing expansion valves and 2-cylinder DC piston compressors. By 1959, Martin Bitzer had expanded his company to 206 employees and was exporting his products to 56 countries.
In 1961, graduate engineer Ulrich Schaufler took over the Bitzer Kühlmaschinenbau GmbH company. He remained as its head until his death in 1979, when he was succeeded by his son, Peter Schaufler. The company had 270 employees and earned sales of 30 million German marks (DM).
