Techcross ECS neutralisation faults: order dosing and TRO checks together
Updated
Sea Clean can service the Techcross neutralisation chain, source dosing parts and check the TRO measurement used by the controller. Order a linked investigation rather than treating a high residual reading as proof of a failed pump.
Key takeaways
- TRO and dosing trends at matching times
- Pump and chemical identification
- Suction and injection arrangement
- Discharge-test window

Follow the measurement-to-dosing chain
Collect the TRO trend, dosing command, pump response and discharge flow for the same operating period. Identify the sampling point and chemical stock used. A command with no delivery calls for a different investigation from a high indicated residual with normal dosing. Retain alarm timestamps so the sequence can be reconstructed.
Identify the chemical and pump assembly
Send the pump nameplate, wetted-end details, suction arrangement, injection point and installed chemical label. Select diaphragms, valves, seals and tubing by the installed assembly and chemical service. Include suction restrictions and injection hardware in the scope; replacing a pump alone will not resolve a blocked delivery path.
Verify the completed repair under controlled operation
Request documented delivery checks, instrument observations and the response of the installed control loop. Use the vessel's approved operating limits and procedure for the trial. Sea Clean can quote pump repairs, TRO service and the necessary spares as one coordinated package with a clear completion report.
Illustrative procurement scenario
The vessel reports high residual oxidant despite a dosing command. Procurement sends the trend and pump details, allowing the attendance to check actual delivery and sampling before selecting the failed component.

Frequently asked questions
Should we increase dosing to clear the alarm?
Use the installed operating procedure. For a persistent fault, Sea Clean can check measurement, dosing command and actual delivery together rather than relying on an unverified setting change.
