Bitzer Kühlmaschinenbau GmbH, a specialist in refrigeration compressors, took 15th place in a study carried out by German magazine WirschaftsWoche. The independent study, in collaboration with Professor Bernd Venohr, a management consultant and economics professor in Munich, analyzed 1,500 medium-sized companies that play a key role in the global market for their specific industry and achieve an annual turnover between 50 million and 1 billion euros.

The ranking is based on the Birch index, which multiplies growth in turnover over the past 10 years by the corresponding percentage growth, thus compensating for the rapid growth usually associated with younger companies and the much higher growth rates of long-standing companies.
