Our Position

We support the ESP you already own.

Aeon Tech Solutions is not a general trading house. Our work starts from the equipment: the field arrangement, the electrode profile, the rapping arrangement, the gas conditions and the emission limit the plant has to hold.

That means a request for collecting electrodes is treated as a question about the field it belongs to — and a rising stack reading is treated as a diagnostic problem before it is treated as a purchase order.

We supply mechanical spares, electrical and control equipment, and the engineering services around them: inspection, performance assessment, troubleshooting, optimisation, retrofit and consultancy.

02 — Electricals

ESP Electricals & Controls

Power supply and control are where the largest performance gains usually sit. Obsolete controllers and ageing TR sets limit the field voltage an ESP can actually hold — and no amount of mechanical work compensates for that.

03 — Services

Engineering services around the equipment.

Available as standalone assignments or alongside a spares supply, during operation or in a planned shutdown window.

Performance not meeting its target? Diagnostic studies, control retrofit, three-phase and high-frequency power upgrades and targeted mechanical refurbishment are covered in full on the retrofit page.
ESP Performance & Retrofit →

ESP Inspection

Internal and external inspection of fields, electrodes, rapping arrangement, hoppers and insulators, with a written condition record.

Performance Assessment

Assessment of field electricals, gas conditions and collection behaviour against the duty the ESP is expected to meet.

Troubleshooting

Fault-finding on tripping fields, low secondary voltage, rapper failures, insulator flashover and control faults.

Performance Optimisation

Tuning of field energisation, rapping cycles and operating parameters to recover collection efficiency.

Maintenance & Commissioning Support

Supervision and support during shutdown maintenance, component replacement and re-commissioning.

Technical Consultancy

Specification review, scope definition, spare part standardisation and retrofit-versus-replacement advice.

04 — Life Extension

Retrofit & Upgradation

Replacing an ESP is rarely the first answer. In most cases the casing and structure are sound and the limitation sits in the internals, the power supply or the control philosophy.

A retrofit scope defined against measured condition — rather than against a catalogue — extends the performance and useful life of the existing installation at a fraction of replacement cost and downtime.

01Control system retrofitReplacement of obsolete controllers with current-generation control, keeping the existing TR sets where they are sound. 02Power supply upgradeHigh frequency or three-phase power supply in place of conventional single-phase energisation. 03Internals replacementField-by-field replacement of collecting and discharge electrodes with corrected alignment and suspension. 04Rapping system modernisationRapping arrangement and cycle revisions where the dust layer is not being released cleanly.

Existing specifications, old quotations, equipment photographs and datasheets are all we usually need to start work on an ESP enquiry.
