The 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.

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.

The 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.

today Amarc DHS (District Heating Substations) engineers, manufactures and installs district heating substations, with a product portfolio of over 300 models, featuring standard district heating substations with a capacity from 10 to 6,000 kW, as well as remote cooling stations with a capacity from 50 to 2,500 kW, plus optionals and accessories, for one of Europe’s most extensive ranges in the industry:

•user Satellites units for central heating systems

•Single living unit wall substations from 10 to 40 kW.

•Wall Substations from 10 to 150 kW.

•Base Substations for hot and superheated water certified CE/PED, from 50 to 6.000 kW.

•Drainage Bag filters for secondary circuit and district

heating network from 15 to 40 m³/h, from PN10 to PN25, for hot and superheated water, max135°C.

•management System to optimize district heating plant, remote setting, telemetering and telecontrol for user substation.

•remote control and hardware tools for communication network specific for district heating plants.

More than 10 years of experience in the industry have created a management and optimisation computer system that can integrate network and substation requirements and functions in one software application, which can make all the difference in terms of profitability for district heating systems.

The functional diagram of the management system so as outlined below represents the consolidation of over 10 years of experience in the design, implementation and managementof district heating plants. Using a standard design and construction facilitates all the operations related to the implementation of district heating systems like the cost of investment and the speed of embodiment, the operating cost and the certification process. It ‘s still possible to integrate existing plants or change functionality based on specific customer needs.
