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 40 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.
