Maintenance That Saves Money: ESP Cells, Carbon & UV‑C Schedules
Set realistic service intervals for pre‑filters, ESP cells, carbon and UV‑C. Lower call‑outs, stable pressure drop and better odour control — without over‑servicing.
Maintenance That Saves Money: ESP Cells, Carbon & UV‑C Schedules
Good maintenance isn’t a grudge purchase — it protects fans, stabilises pressure drop and prevents odour complaints. " "Here’s a pragmatic schedule you can adopt and adapt.
Pre‑filters
Check weekly; wash with warm water and degreaser. Dry fully before refitting. Typical interval: 1–4 weeks depending on load.
ESP collector cells
Clean every 4–8 weeks. Use approved alkaline cleaners; rinse and dry thoroughly. Record works in a logbook.
Activated carbon
Plan change‑outs before breakthrough. If odour rises between services, check upstream ESP performance and airflow.
UV‑C/ozone stages
Replace lamps around 12,000–13,000 hours. Verify door and airflow interlocks after works. Never run ozone without airflow proving.
Why schedules pay back
Lower ΔP = lower fan energy and fewer overheating faults.
Cleaner ducts support TR19 hygiene intervals.
Predictable visits avoid emergency call‑outs at peak trading hours.
