• Ensure safe and compliant operation in an ATEX‑classified environment, requiring explosion‑protected components and reliable motor‑temperature monitoring.
• Implement a stable and integrated drive solution for precise pump control and secure handling of liquids and chemicals.
• Reduce commissioning complexity by using Siemens’ diagnostics, safety functions, and engineering tools for verifiable performance and easier troubleshooting.
• Support the customer’s long‑term shift toward climate‑neutral and safe industrial production, without sacrificing reliability or efficiency.

CTS integrated the SINAMICS G220 variable‑frequency drive to enable precise, safe, and energy‑efficient pump control within the customer’s ATEX‑classified process environment.

ATEX‑approved Siemens modules were used for continuous motor‑temperature monitoring and equipment protection, ensuring safe operation in hazardous zones.
The drive was installed in a compact control cabinet and connected via PROFINET with PROFIsafe, providing high‑performance communication and functional safety. Commissioning was carried out using the integrated SINAMICS G220 Web Server and Startdrive in TIA Portal, enabling fast parameterization, streamlined setup, and clear visibility of ATEX‑related alarms and diagnostics.

Using the SINAMICS G220’s advanced vector control, the system delivered stable and accurate flow regulation across varying load conditions, with Siemens’ Safety Integrated functions (STO, SS1) supporting the required safety levels for chemical handling.
