The new head office of Bitzer Kiihimaschinenbau GmbH in Roggenburg, Germany, for the production of screw compressors was put into operation at the end of 2003. With a capacity of more than 25,000 compressors per year, this plant has become one of the largest enterprises in the world producing screw compressors for air conditioning and refrigeration systems. The preconditions for the construction of the new plant and the transfer of all production capacities from the old plant in Sindelfingen were the significant expansion of Bitzer over the past years and, in particular, the success of screw compressors. The annual increase in their output was more than 35%, and the old production was bursting at the seams! At the same time, the output of reciprocating compressors also increased significantly. Their production in Europe was completely transferred to the factories of the cities of Schkeuditz (Germany) and Castelo Branco (Portugal). This decision made possible the material and technical separation of the two production technologies, which had a positive effect on the total activity and costs of the companies. In addition to the named European enterprises, Bitzer compressors are manufactured according to around the world. Factories in Brazil and China produce a range of compressors to meet the needs of the local refrigeration and air conditioning markets.
