This year, the THERMOINTECH company was represented at two stands. At the collective exposition of RUSNANO, the model of the Autonomous Thermoelectric Power Source was placed, and within the framework of the specialized exposition "Import substitution in the gas industry", the Thermoelectric generator based on thermoelectric modules and the Autonomous Thermoelectric Power Source ATPS-5000 at full size placed on the open platform of the Forum, were represented at the Gazprom PJSC stand. This installation is intended for powering a complex of radioelectronic equipment (CREE), linear telemechanics and automation, communication systems, cathodic protection and shut-off valves with direct electric current on main gas pipelines where there are no power lines at all, there is no opportunity to connect or connection is not economically feasible, but there is natural (oil associated) gas. ATPS is able to operate reliably and for a long time without maintenance in climatic zones with a moderate and cold climate, at temperatures from -60 to +50 C ° (with 1 category of location). All devices and systems produced by THERMOINTECH LLC company are able to provide equipment for oil and gas industry with electricity for a long time and reliably. And the use of Russian components allowed the company not only to participate in the program "Import substitution in the gas industry" and to support Russian producers, but also to minimize the cost of production. Within the framework of the 6th St. Petersburg International Gas Forum, a meeting was held on the issues of technological development of Gazprom PJSC, where the General Director of THERMOINTECH company Abayev Yakov Semenovich delivered a report on the topic: "Use of Thermoelectric Generators in Autonomous Power Sources". As a result of the 6th International Gas Forum held within the framework of the specialized exposition of Gazprom PJSC, "Import substitution in the gas industry, THERMOINTECH LLC was awarded a diploma.
