The purchase price of an infrared tube is only one part of replacement cost. A mismatched lamp can add downtime, installation work, damaged holders, uneven heating or rejected product. A useful total-cost review starts with compatibility and includes maintenance access, spare strategy and process verification.
Record the original manufacturer and part number where available, plus voltage, wattage, overall length, heated length, tube diameter, terminal style, lead length, reflector coverage and mounting orientation. Photographs help, but critical dimensions should be measured and placed on a drawing.
A lamp that physically fits can still be electrically or optically incompatible.
| Cost category | Questions to record |
|---|---|
| Lamp purchase | Price, freight, minimum quantity and lead time |
| Downtime | Lost production, access time, cooling and restart |
| Installation | Labour, holders, leads, connectors and alignment |
| Process loss | Scrap, slow start, profile adjustment and quality checks |
| Inventory | Critical-spare quantity, storage condition and obsolescence |
| Maintenance | Inspection interval, cleaning and failure analysis |
Check ceramic holders, spring contacts, terminal torque, cable insulation, reflectors, guards and cooling paths. Overheated or loose connections can damage a new lamp quickly. Remove contamination using the approved method and avoid touching quartz with bare hands.
If several lamps fail in the same position, investigate the circuit, airflow, vibration and mounting rather than treating each event as random lamp life.
Prioritise lamps that stop the entire line, have long lead times or use a special termination. Store spares in their protective packaging in a clean, dry area and label them with the equipment location and verified drawing revision. Rotate stock only when the lamp specification is unchanged.
Review YFR infrared replacement lamps and heating modules.
Record zone current, warm-up response and product temperature across the working area. Compare the result with the approved process recipe before returning to full production. For multiple-lamp banks, replace only the number required by the maintenance policy and then confirm profile uniformity.
It depends on the process, lamp condition, access cost and uniformity requirement. Use failure history and temperature-profile data.
No. Voltage, dimensions, heated length, terminals, reflector and mounting are also critical.
Capture the complete lamp, break location, terminals, holder, reflector, wiring and equipment position before cleaning.
Record the installed part number, electrical readings, zone settings, temperature profile, product result and installation date in the equipment history.
Send YFR the lamp photos, drawing and operating data for a replacement review.
