Troubleshooting
Plate heat exchanger troubleshooting
When a unit isn’t delivering the temperatures it should, is leaking, or is costing more to run, the first job is to find out why.
Overview
Diagnosis before parts
Poor performance can come from the exchanger itself — fouling, damaged plates, incorrect compression — or from the system around it: flows, temperatures and control settings that no longer match the original design.
Troubleshooting separates the two. We look at the unit, its operating data and its original configuration, so the fix addresses the cause rather than the symptom.
Warning signs
When to call us
- Outlet temperature not reaching setpoint
- Pressure drop higher than design
- Leaks that return after tightening
- Capacity lost after a process change
- Rising energy or pumping costs
- Two identical units performing differently
