The history of T&T Sistemi is one of research and technology. In 1995 T&T was established as a company specialized in the design of software for control systems, capable of working on large-scale projects, highly complex systems and metro-railway-tram systems integration. This know-how comes from the company's experience in producing control panels since the early 1980s; that ability has evolved over the years through investments targeting the improvement of skills and internal procedures. This decision has led to a work process that can put together products and services based on the needs of individual clients. The result is T&T Sistemi: three locations (two in Italy and one in Brazil), nearly 150 employees, of whom 80% hold degrees, and a list of references that includes some of the biggest companies in the Oil & Gas, Power Generation and Transportation industries. The company continues to use the time-honored approach for which it is known: complete control of processes and absolute reliability. T&T Sistemi's head office is located at Levane in the province of Arezzo. This facility is home to the sales and design departments, as well as the entire production line. T&T Sistemi has another Italian operations office in Florence, which is mainly engaged in design and forms part of a network that combines different skills and ensures customers more effective solutions.
