Strategic partnership
3L Srl and SIEMENS Italy: a partnership of excellence.
Throughout its professional and business growth, 3L Srl has built important partnerships with clients across a wide range of industrial sectors — among which we are proud to count SIEMENS Italy, and in particular the Siemens Competence Center of Milan (CCMilano).
Working with SIEMENS CCMilano gave us the opportunity to demonstrate our expertise, services, and technical knowledge on a large scale, while also developing innovative, high-technology software packages. The goal is to deliver control and regulation solutions that — integrated within SIEMENS industrial automation equipment — make complex problems simple and intuitive to manage.
The software packages developed exclusively for SIEMENS Italy are distributed to SIEMENS clients through CCMilano and the technical-commercial network operating in the Automation and Drive sector.
This nationwide opportunity has allowed us to build a deep collaborative relationship with SIEMENS Italy and its clients, and to continuously enrich our expertise in regulation, automation, and control by successfully addressing the technical challenges presented to us over the years.
