PLC-Based PID controller for marine boilers

At Global Boiler Services, we offer advanced PLC-based PID controllers that consolidate multiple control functions into a single, efficient system. This upgrade reduces complexity, simplifies maintenance, and provides an excellent process overview, helping you save time in your day-to-day boiler operation.

One controller – multiple functions
Instead of relying on several separate controllers, our PID controller integrates multiple control operations within one unit. Typical control loops include:

Oil/air ratio

Water level

Steam pressure

By replacing multiple devices with one centralised system, you reduce hardware requirements, spare parts inventory, and potential failure points.

Siemens S71200 CPU at the core
The system is built on the Siemens S71200 CPU, ensuring:

Userfriendly operation via HMI touch screen

Future expansion capability for additional control loops

Worldwide spare parts availability

High reliability and industry-proven performance
