Retrofit legacy equipment with PLC, DSI, recipe-driven controls, and instrumentation.
We retrofit legacy equipment with PLC and DSI control, recipe-driven setpoints, and instrumentation. The work starts with an assessment of the existing system and ends with commissioning against the agreed operating requirements.
Review panels and drawings, trace sensors, and document the existing control scheme before defining the retrofit.
What the line has to make, and what setpoints each product needs. This comes from your operators, not from us.
PLC, DSI, and the instrumentation to see what the equipment is doing. We scope what has to be replaced and what can stay.
Panel built, PLC installed, sensors placed, and the whole thing tied into the equipment that is already running.
Run every recipe. Confirm the setpoints hold and the readings match what the line is actually doing.
Discuss the items your project needs. Final scope is confirmed with your quote.
We assess the equipment as well as its controls, including the burners, drives, and sensors that affect line operation.
We assess which panels, instruments, and controls need replacement and which existing components can remain.
A line that runs blind is a line you cannot optimize. The point of the retrofit is that you can finally see what it is doing.
Service coverage
Usually not. Retrofitting legacy equipment with modern control is the core of this work. We scope what has to go and what can stay.
One recipe per product, with setpoints that hold. You stop relying on which operator is running the line that shift.
The assessment covers both the control system and the equipment it operates. That helps define whether the work belongs in the panel, the mechanical system, or both.
Yes. We audit what is there first, whoever put it there.
Share your drawing, equipment details or the issue on your line. We’ll review the scope with you.
