BITZER is the world’s largest independent manufacturer and specialist for refrigeration compressors. Refrigeration and air conditioning technology are of inestimable value in our world. They allow food to be transported over thousands of miles and then be stored, without loss of freshness and quality. In buildings, air conditioning brings a distinct improvement to living and working conditions. Every day blood banks save the lives of countless people, while many products, such as semiconductors, can only be manufactured with this technology. In all these situations it is essential that the refrigeration and air conditioning systems function reliably. To put it another way: Their heart must beat dependably. This 'heart' is the compressor. For over 80 years now, BITZER has been manufacturing refrigeration compressors, condensing units and pressure vessels for refrigeration and air conditioning. The BITZER Group has sales companies and production sites for reciprocating, screw, and scroll compressors as well as pressure vessels all over the globe. In 2014, 3,400 employees generated sales of €657 million.

BIV represents the enterprises responsible for the design, installation, maintenance and repair of refrigeration and air conditioning equipment. It supports the interests of its members in the skilled crafts of refrigeration plant construction in accordance with the legal requirements.
