IMPORTANT COMMUNICATION

NEXT TECHNOLOGY GROUP sells to Dylog Italia SpA its subsidiary TESAR SpA: the group company dedicated to the development of MES solutions.

_______________

Next Technology Group: leader in technologies for energy, automation, metal sheet working and software, announces the transfer of 100% of share capital of its subsidiary Tesar S.p.A to Dylog Italia S.p.A.

Tesar S.p.A is active in the industrial and services sector; it is leader in software development for data collection, planning, control, production and quality management.

Dylog Italia S.p.A is active in the design, development and commercialization of operational software and services for companies and service providers.

Tesar, to date, employs 60 collaborators with a turnover of more than 5Mln€. The company has become part of Next Technology Group in 2012 with 50% of its shares, ending up being controlled with the totality of its equity in 2015. The acquisition enabled Tesar to become one of the most well-known players on the Italian market, shortly resulting in both turnover and personnel employed doubled in size.

The evolution of the group activities, favoured over time an ever-growing commitment in the world of industrial production of dry type transformers and of metal sheet working, for applications including Marine & Offshore, Oil & Gas, Power Generation, Industry, TractionBuilding & Infrastructure, Renewable Energy.

The following companies, in fact, have become part of the group: TMC Transformers SpA, Ritz Power Transformers GmbH, Marnate Trasformatori, Officine Tironi, and soon, following the opening of a new productive unit, “TMC Transformers Low Voltage”.

This process delineates a precise group strategy, that for this reason, considered necessary to proceed with the transfer of Tesar SpA to Dylog Italia SpA.


TMC: THE FUTURE OF TRANSFORMERS’ WORLD

It’s out now on EASY ENGINEERING our interview concerning TMC company’s activities and news, but also about the current trends of the transformers market.

_______________

Easy Engineering: What are the main areas of activity of the company?

TMC Transformers: TMC Transformers products are realized for distribution and special applications: two very different souls combined together under a single roof, to offer to our customers the most suitable technology and service. The company is mainly working on dry type transformers and reactors for all the applications worldwide. We are talking about industry, simple distribution for building and infrastructures, traction substations, marine and offshore, oil and gas, renewable energy, battery storage, mining, data center, power plants, e-mobility.

For marine and offshore application, TMC supplies marine converter transformers, distribution transformers and reactors, applied to Naval vessels, cruise liners, container vessels, offshore oil & gas vessels down to smaller research vessels.

For Power Generation, products are designed to fulfill the needs of simple distribution or excitation systems.

In Industrial context, every industrial specialty needs transformers and inductors to handle correctly electric power to feed, control and operate machinery. 

In the Oil and Gas sector TMC can fulfill needs in any area, from drilling, onshore and offshore production and transportation with ships or pipelines, all the way through to final processing in the refinery.

In the last couple of years, we developed especially transformers for outdoor installation (so either for mining, battery storage, some industrial plants or plants for energy production), meaning transformers suitable, from IP34 to IP56 or even IP68, for going underwater. We challenge the market of dry type transformers putting our solutions outdoor where there could be a quite harsh environment.

E.E: What about new products?

TMC Transformers: In the last month, following the acquisition of RITZ power transformers, we acquired a new technology, called GlasVac: a new cast technology with a higher level of fiber glass, using casting processing vacuum. This technology has both the benefit of using fiber glass, making transformers more resistant especially from a mechanical point of view, and on the other side the vacuum process guarantees low levels of partial discharge. This technology will be used as alternative to the traditional cast and will be potentially applied to a number of applications where it can be effectively used to give an advantage. 

The most innovative development concerns outdoor transformers where we introduced new ways to protect the transformers and innovative solution to cool it down. We can now deliver a proper solution for any specific ambient challenging the most polluted, humid or aggressive environment. As an example…

MARINE & OFFSHORE SECTOR: A COMPLEX AND SUSTAINABLE WORLD OF TRANSFORMERS

To celebrate our participation at Europort exhibition we have published an article on Marine Link website.

_______________

“Today, in the transformers market and especially in the marine & offshore application, a new trend is gradually establishing: the use of green technology with full ambient compliant transformers that are recyclable and not polluting, which can be used in outdoor application, where typically companies use oil solutions instead.

A very clear tendency in this context is the use of electric ferries. These ferries typically carry batteries that must be charged quickly at the port in order to withstand the entire journey to the port of arrival.

The transformers required are very special, typically with several secondaries, with particular impedances and need to withstand a large load for a short period.

TMC Transformers has been participating in the design and manufacture of the transformers in several of these projects during the last two years, in collaboration with the engineering of several important ship designers. All this must be complemented by a dedicated and expert service department. Repair operations on board are sometimes complex and often urgent, so the personnel dedicated to this task needs to be top-notch. 24/7 availability is required.

Moreover, the marine sector is very demanding, not only technically but also in terms of project management. It is necessary to have professionals with extensive experience in this highly specialized area.

Technically, this market is heavily regulated by several standards and certifications that managers must know perfectly. In addition to the design itself, an analysis of structures by finite element approach helps to verify the feasibility of the proposed solutions.

One of the differentiating features in a marine transformer is the type of cooling. This will influence not only the size and weight of the final solution but also its efficiency and resilience to failure. The most common cooling types are Air Natural (AN), in which the transformer does not require external cooling support, and Air ForcedWater forced (AFWF) where the transformer requires a highly specialized air-water heat exchanger integrated in its enclosure, where water is used to cool down the air inside and consequently, the transformer’s coils.

Another common characteristic is the use of integrated pre-magnetization transformers to help with inrush currents that can damage the main transformer.

Lastly, given the environment where these transformers have to work, a proper corrosion protection (metal treatments and painting) is necessary.”
