QEQI / APPLICATION

Heat exchangers & condensers

Review water-side fouling, pipe layout and maintenance history before selecting an electronic treatment configuration.

01 / THE ASSESSMENT

Begin with the operating context.

Start with deposits and operating conditions.

  • Exchanger type and pipe layout
  • Flow and operating temperatures
  • Deposit analysis and cleaning history
02 / SYSTEM COMPONENTS

Products to assess for this application.

03 / VALIDATION

Agree on what to measure.

Record the baseline and compare equivalent operating conditions over an agreed period.

Treatment boundaries

Compare like-for-like operating periods. Load and temperature changes can affect observed performance.

04 / PROJECT CONTEXT

Start a useful conversation.

  • Exchanger type and pipe layout
  • Flow and operating temperatures
  • Deposit analysis and cleaning history

A useful project record includes equipment configuration, operating baseline and the agreed monitoring period.

05 / APPLICATION FAQ

From configuration to daily operation.

Practical considerations for this application, its existing treatment and performance review.

How can I distinguish scale from other fouling?

Combine deposit inspection, water analysis and maintenance records. Mineral deposits, corrosion products and biological fouling may coexist and require different controls. A pressure-drop change identifies a system change but does not, by itself, identify the material causing it.

Which operating values make comparison useful?

Record inlet and outlet temperatures, flow, pressure drop, duty and cleaning history on the relevant circuits. Compare equivalent operating conditions using the site's engineering method. A temperature change without corresponding load and flow information may be misleading.

Should cleaning and inspection continue?

Keep the established maintenance programme during evaluation. Change cleaning intervals only after reviewing equipment condition and operating records. Preserve pressure limits, process requirements and inspection access; treatment equipment does not replace the exchanger's maintenance instructions.

ENGINEERING INPUT / SELECTION CRITERIA

A specification is only the starting point.

A useful configuration connects product ratings to the actual operating environment.

Assessment areaSite informationEngineering decision
Pipework & connectivityOutside / nominal diameter, material, branches and closed electrical loopsModel fit, clearance and signal conditions

Water & processHardness, suspended solids, temperature and existing treatmentTreatment roles and processes to retain
Operation & maintenanceLoad profile, cleaning history, inspection and discharge accessComparable baseline and practical service access

Electronic scale control, particle separation and water-quality compliance are separate responsibilities. A site may need several coordinated processes. Neither scale control nor filtration universally replaces softening, membrane treatment, disinfection or chemical management.

PERFORMANCE EVALUATION / MEASUREMENT

Make the operating evidence comparable.

01

Establish a baseline

Record equipment, deposits, cleaning intervals and existing water-treatment practice before changes.

02

Track operating conditions

Record load, flow, temperature, water quality and any parallel process changes during the observation period.

03

Review defined indicators

Compare cleaning records, pressure drop, heat-transfer behaviour or solids collection as appropriate to the application.

04

Attribute results carefully

Separate measured results, operator observations and financial estimates. Do not assume every change comes from one device.
