By 2020, a global modernization of production has been carried out. The repair of the central entrance was carried out. An energy center consisting of a block-modular boiler house and two gas-piston power plants has been put into operation.
In 2021, the equipment manufactured by LLC "Termotron-Zavod" received a Conclusion confirming the production of industrial products in the territory of the Russian Federation.
In 2023, the company's specialists implemented the first successful case for replacing the Austrian switch drive for tram translation into Russian.

By 2010, the directions of solar energy received active development.
The company produces autonomous solar stations, as well as autonomous lighting systems.
In 2014, a complete modernization of the foundry began. A modern, more environmentally friendly induction furnace with a capacity of up to two tons of cast iron per melting has been installed. An automatic molding and filling line with the use of a cold-hardening mixture has been introduced.
In 2018-2019, the MPC-T microprocessor centralization system and the first domestic switch drive for SPT tram transfers were developed and mastered.

In 2004, on the basis of the enterprise, a test center for automation, telemechanics and signaling of railway transport was established and accredited (IC ATS ZHT CJSC "Termotron-Zavod").
In 2005, the production of VSP switch drives was mastered and started. Then the production of metal-ceramic elements for absorbing devices of railway cars was started.

In the 1990s, the development of products designed to ensure traffic safety on railways began.
In 1998, the international quality system ISO 9001 was introduced at the plant.
Certificates of conformity for choke transformers DT 1-150, 2DT 1-150, DT 0.6-500, DT 0.6-1000 issued by the Register of Certification on Federal railway transport were obtained.

Since 1977, several types of diagnostic equipment for automotive engines have been developed.
By 1980, the production of ion-beam equipment of the Vesuvius type was mastered.
Six years later, the development of physical and thermal equipment was started.
Since 1989, the development of equipment for the latest technology — X-ray lithography has begun.
The company was entrusted with the development and manufacture of a set of physical equipment for a 600 MeV superconducting composite lithographic storage device.

The construction and commissioning of the plant's production facilities was completed by 1972. An electrical installation shop was created, a site for the manufacture of plastic parts was organized, a technological line of electroplating coatings was introduced, the technological process of cutting stainless steels with plasma was mastered.

Bryansk Plant of Technological Equipment (BZTO) was established on July 1, 1965. The reason for this was the Minister's order No. 95 of June 19, 1965. The construction of the plant, which was supposed to provide special technological equipment to the rapidly developing electronics industry, began in 1962. A plot of land with an area of 14 hectares was allocated for the construction. The construction of the enterprise was headed by its first director Viktor Ivanovich Sokolov.
One of the most important events of that time was the first melting carried out in the foundry on December 27, 1965.
