The lowest infrared lamp quotation is not automatically the best value. A useful RFQ makes every supplier quote the same electrical, dimensional, optical, testing and delivery requirements. This prevents a low initial price from becoming downtime, modification work or rejected product.
State the process, material, heated area, target temperature, speed or dwell, working distance, environment and current problem. For a replacement, add the equipment model, original part number and failure history.
Include voltage, wattage, tube type, overall and heated lengths, cold ends, reflector coating, termination, leads and mounting references. Mark mandatory values and acceptable alternatives. Give the drawing a revision and date.
| Category | Questions |
|---|---|
| Technical match | Are deviations listed and drawing approved? |
| Verification | Which visual, dimensional and electrical tests are included? |
| Commercial | Price, minimum quantity, tooling and validity? |
| Delivery | Sample and production lead time, packaging and freight? |
| Lifecycle | Traceability, complaint process, spares and engineering support? |
For a new or critical replacement, validate a small sample before committing to production quantity. Check fit, current, response, temperature profile and product quality. Record the accepted construction and do not approve silent substitutions.
Include freight, import costs, inspection, installation, downtime, minimum stock and expected replacement effort. Do not use unverified lamp-life claims as the only lifecycle comparison.
Compare YFR infrared lamp categories and system components.
Include it when validated; otherwise provide the material and process so the emitter choice can be reviewed.
It creates a shared reference for dimensions, terminations, reflector and later change control.
Only when coverage, exclusions, operating conditions and claim handling are clear.
First confirm technical and process compatibility; price comparison is meaningful only after that.
Send YFR the process data and drawing for a documented quotation.
