AMAR DHS: HE OMPANY he company was established in 1998, under the name of Amarc tecnologie, its aim being to harness the considerable experience gained in the industrial heating and process control industry since 1950, and to consolidate and turn this expertise into reproducible scientific and technological principles. During this time, the company partnered leading Italian and foreign companies in developing research projects, up to the construction and installation of components, machines and plants, which also involved the registration of some international patents. he cover shows an image of New York, where, at the end of 1800, was installed the first district heating network. A tribute to the origins of our industry that our company has greatly contributed to develop in Italy offering reliable products of high quality, technology and design setting the standard in the domestic and foreign markets. More recently, the company became involved, for some applications, in district heating - a technology which was barely known or developed, at least in Italy. After several years of testing and operations, the company decided to invest heavily in this sector, and above all in technical product and production process development, as well as in automatic control and supervision systems. 2 WWW.AMARDHS.I
