With a wealth of experience in water piping fittings Gustav Mock and Wilhelm Krumsiek established Mock & Krumsiek in Altenburg on 21 November 1879. The expansion of the product lines from water piping to fittings for vapour, gas, petrol, oil, coffee machines and beer resulted in steady growth. In 1886, this culminated in a new three-storey building with a boiler unit, a steam engine and a metal foundry.

The founders made an effort to use modern housing and seal materials, to build for high flow rates and to ensure 100 percent pressure and tightness testing. The company‘s already strong commitment to customer wishes was underlined by around 10,000 individual part models by 1929.

The second world war led to dispossession in 1948 and a focus on small fittings for refrigeration and air conditioning in VEB Armaturenwerk Altenburg. Its reprivatisation as management buy out by 19 dedicated employees led by the engineer Jürgen Dobmeier and business economist Ursula Kutzke in 1992 was followed by its acquisition by Karl-Fritz Jordan in 2002.

With its focus on fittings and accessories for refrigeration compressors and refrigeration system construction, the 2000s were characterised by a strengthening of customer relations worldwide, product diversification and the integration of the companies FAS from Hamburg and Hans Nobis from Cologne.

AWA moved away from the city to the ‘Am Weißen Berg’ industrial area in 2002 in order to expand its production capacity. It now has a production area of 9,900 metres squared, with its own electroplating shop.

AWA has been part of the Bitzer Group since 2013. This concentration of industrial expertise and close collaboration has produced numerous new developments. The global use of AWA fittings and accessories has since expanded in the international Bitzer network.

Today, 200 employees work in manufacturing, administration and development in a factory which remains deeply rooted in Altenburg in Thuringia. Due to high vertical range, products pass through mechanical production, assembly, soldering and glass furnaces, the welding workshop, the in-house electroplating workshop and strength and tightness tests.

Just like the founders Mr Mock and Mr Krumsiek, everything AWA does remains centred on the success of the customer. International compressor manufacturers as well as global system integrators and wholesalers value AWA's expertise and solutions to meet today's challenges with natural refrigerants such as CO2, NH3, HFOs, flammable refrigerants and refrigerant oils.
