President's Letter

Dear CWT client,

Physical water treatment has over the years successfully proven to be an efficient method to improve the quality of our water without adding chemicals or salt. Nowadays, it has become even more important to capitalize on technologies which do not harm our environment but rather try to create an optimal balance between man and nature. Our production is based on such a technology and is the result of thirty years of constant research and improvements in the field of physical water treatment by Christiani Wassertechnik GmbH (CWT). Our latest product generation continues to provide you with reliable German quality combined with an extensive warranty.
I would like to thank you for your trust in this technology and our expertise in the field of physical water treatment. Many satisfied customers worldwide are the measure of the success of Vulcan which will become apparent also to you.

History

History - Since 1948

1948 - 1970: The company was founded in 1948 by Hans Otto Christiani as „Hans Christiani & Co.“ in Cologne, Germany. He developed and manufactured his own water pumps and electronic controls. Driven by the triggering economic force in Germany (the "Wirtschafts-Wunder“) the business rapidly grew in size. In 1959 the production moved to a larger industrial park in Cologne-Weidenpesch.   Scale_Rust_
     
1970 - 1980: After successfully graduating from university as a business engineer, Rolf Christiani joined the company in 1975. He soon identified the growing demand for eco-friendly technologies. Thus, the development of physical water treatment units was added to the portfolio. Two years later in 1977 the first line of anti-scale devices was introduced to the market – the Catronic® Series. The successful products soon also captured the international market such as in France, Italy, Spain, Hungary and Scandinavia.   Scale_Rust_
     
1980 - 1990: In 1980 the founder of the company Hans Otto Christiani passed away. His son was then in charge of the business. He decided to focus on the future market of „physical water treatment“ and expanded the manufacturing and distribution of the products. In 1984 the company was restructured under its current name „Christiani Wassertechnik GmbH“.   Scale_Rust_
     
1990 - 2000: The fall of the iron curtain in 1989 opened up a new market for physical water treatment. In 1991 after a long period of research by Rolf Christiani an improved anti-scaling device was introduced – The Vulcan Line. The market quickly adapted to the new device and more than 150,000 units were sold in Germany alone. In May 1990 CWT moved to the manufacturing location of Eschweiler, Germany.   Scale_Rust_
     
2000 - 2010: In 2005 Cedric Christiani joined the company and started to introduce the Vulcan technology to the international market. Soon larger units for industrial applications were introduced and successfully tested on the field. A fast expansion into Asia, South America and the Middle East called for extended marketing. In 2006 Jessica Christiani, who previously worked as a marketing specialist joined the company as well. In the same year headquarters were moved to the German capital city, Berlin.   Scale_Rust_
     
2012: The third generation in the family business is keeping their vision of  "Water as it should be“.   Scale_Rust_

Corporate Responsibility

Corporate Responsibility

Unfortunately not everybody in the world has access  to clean water. Over 60% of the world’s population suffer from lack of water and have no access to clean, safe drinking water. The situation in third world countries is especially worsened by environmental disasters, drought and long, raging wars.    
     
It is our responsibility to help - We want to help
make a difference.
Since May 2005 we have been supporting the well building project of the charity organisation ‘Plan International Deutschland’. The wells sponsored by CWT provide clean water to over 300 people daily in the African town of Guinea.

Sodis
SODIS (short for Solar Water Disinfection) is an initiative of Eawag, the Swiss Federal Institute of Aquatic Sciences and Technology. For more than 10 years, it has been  providing people in developing countries with access to clean drinking water. The aim is to educate the people on how they can disinfect water themselves in a few hours and thus prevent diarrhoeal diseases.
