Careful investment – Radiator manufacturer relies on clear modernization concept and solutions from Siemens 

With an output of more than six million radiators, the Stelrad Radiator Group (Stelrad) is one of the largest manufacturers in Europe. As part of production modernization, the existing automation was equipped with the latest Simatic S7-1200 and Simatic S7-1500-control and drive technology from Siemens.

With an output of more than six million radiators, the Stelrad Radiator Group (Stelrad) is one of the largest manufacturers in Europe. As part of production modernization, the existing automation was equipped with the latest Simatic S7-1200 and Simatic S7-1500-control and drive technology from Siemens.

The existing automation system was fitted in the 1990s and was therefore no longer up-to-date. For the modernization, the company had very clear plans: "Our aim was clear from the outset – we wanted a system that offered us the maximum differentiation at a competitive price. At the same time, we wanted to keep product delivery times as short as possible,"recalls Marc Peeters, Production Manager at Stelrad. Product traceability and the energy efficiency of the production line also played a central role: the shorter the lead time for radiator production, the more energy can be saved. For the actual planning, Stelrad turned to Belgian system integrator and Siemens partner CKS Elektrotechnik. 

Seamless customized automation

"The greatest technical challenge was integrating the new automation structure– the switch control cabinet – into the existing system landscape," Peeters explains. The experts had to choose components carefully. These included Simatic S71200 and Simatic S7-1500 PLC controllers, Sirius 3RW44 soft starters, Sinamics G120C drives, and various Simatic comfort panels. All components communicate via the open Industrial Ethernet standard Profinet. To ensure the smooth running of the project within the planned implementation time, all project participants collaborated closely, consulting at regular intervals. In addition, employees were involved at an early stage so that they could become familiar with the new technology. As a result, the project was completed within the tight time frame of the annual summer shutdown. 

Project success across the board

The close collaboration was worth it. The new system landscape was implemented within 14 days. In addition, Stelrad has since benefited from a 50 percent reduction in lead time, particularly energy-efficient plant operation and short delivery times. The option of storing user know-how in the system means that in future, production will not be adversely affected by employee absence (for example due to illness), since operator knowledge is stored centrally and can be accessed by all.
The Siemens solution, which was implemented in just 14 days, has enabled the company to reduce radiator lead times by 50 percent.

Shorter delivery times and increased energy efficiency – the modernization, as shown in the picture with Simatic S7-1200 plc, Scalance Switch and Sitop USV battery module, has brought numerous advantages for Stelrad and its customers.
For Stelrad, it was important to integrate the new automation structure into the existing system landscape. All components used by Siemens, such as the Simatic S7-1200 or S7-1500, PLC controller, Sinamics G120C drives, Sirius 3RW44 soft starters and the Simatic comfort panels shown here communicate via the open Industrial Ethernet standard Profinet.
