Case Studies

Giving aging equipment a second life.

Real examples of Meray evaluating existing industrial equipment, modernizing the controls where it made sense, and working with plant teams to keep valuable machinery productive.

Our Approach

We don’t replace technology just because it’s old.

Every machine is different. Sometimes modernization means a new PLC, HMI and control panel. Sometimes the existing PLC should stay. Sometimes the automation system needs to be rebuilt around a mechanically sound machine. Our job is to determine what the equipment actually needs.

  1. 01UnderstandLearn how the machine is supposed to operate.
  2. 02PreserveKeep the mechanical equipment and controls that still have value.
  3. 03ModernizeUpgrade only what actually needs it.
  4. 04IntegrateConnect the new controls to the existing machine.
  5. 05CommissionTest, verify and hand off a working system.

The Projects

Four machines. Four different modernization decisions.

A corrugated manufacturing line with paper rolls and an operator control station with an HMICorrugated

Corrugated Equipment Controls Modernization

Aging controls → New PLC/HMI panel → Existing machine integration

A new control architecture was designed and integrated with the machine's existing I/O, analog signals and field systems.

Spiral Freezer Controls Modernization

The freezer worked. The PLC worked. We modernized the controls environment around them.
