Plate Heat Exchanger Cleaning explained

Chemical cleaning in place restores most brazed exchangers at a fraction of replacement cost, with before and after performance figures recorded.

  • Chemical circulation clean: Distinguish a pump fault from air, restrictions or closed valves elsewhere in the circuit.
  • Scale and biofilm removal: Water condition, cleaning and equipment suitability should be checked against the manufacturer’s requirements.
  • Before and after readings: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
  • Passivation and rinse: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.

Interpreting the reported fault

A planned visit should establish condition and identify deterioration. An existing fault may need separate diagnosis and parts. Agree which assets, cleaning tasks, functional checks and records are included, and base the interval on manufacturer guidance and operating conditions.

  • Reported symptom: falling output and rising return temperatures on a scaled unit
  • Record when the problem started and any recent changes
  • Keep fault codes and model details for the assessment

Maintenance is not a breakdown repair

A planned visit should establish condition and identify deterioration. An existing fault may need separate diagnosis and parts. Agree which assets, cleaning tasks, functional checks and records are included, and base the interval on manufacturer guidance and operating conditions.

  • Confirm equipment model and access before the visit

Labour and the work to be agreed

Engineer time is £120+VAT per hour with a one hour minimum. The time and materials required depend on the diagnosed fault and access. Ask for the repair scope, any additional parts and the return-to-service checks before proceeding.

Plate Heat Exchanger Cleaning: scope, checks and next steps

Chemical cleaning in place restores most brazed exchangers at a fraction of replacement cost, with before and after performance figures recorded.

What the reported symptom tells us

falling output and rising return temperatures on a scaled unit. Record when this occurs, what changed beforehand and whether other equipment is affected. These observations narrow the investigation; they do not prove which part has failed.

Maintenance is not a breakdown repair

A planned visit should establish condition and identify deterioration. An existing fault may need separate diagnosis and parts. Agree which assets, cleaning tasks, functional checks and records are included, and base the interval on manufacturer guidance and operating conditions.

What each check helps establish

Scale and biofilm removal

Before and after readings
