At Sigma we believe the conceptual design is the most important aspect of a Process Control System as it is the foundation for the plant's future, including the ease of upgrading the systems when next required. A sound approach to system design facilitates a system that is flexible and scalable.

This ultimately leads to significant advantages as future modifications and expansions to the control system are not cost prohibitive due to the ease of implementation. Our systems integration approach is based on total supply and delivery with a single point of responsibility.

The services can include the following, depending upon your requirements and the scope of work:

  • Automation Software Development
