Commissioning converts an infrared dryer from installed equipment into a controlled production process. Acceptance should verify mechanical construction, electrical load, airflow, temperature profile, interlocks, product quality and documentation. A warm lamp or dry-looking sample is not a complete acceptance test.
Verify drawings, lamp part numbers, guards, supports, reflector orientation, clearances, terminal torque, earthing, fan rotation and sensor installation. Confirm that tools and packaging have been removed and that the line is safe to energise.
Record supply voltage and zone current at controlled settings. Test local and remote operation, controller signals, overtemperature protection, fan proving, emergency stop and line-stop power reduction. Verify restart behaviour after loss of power.
| Test | Evidence | Acceptance basis |
|---|---|---|
| Electrical load | Voltage and current by zone | Approved design and tolerances |
| Airflow | Direction, setting and exhaust condition | Process and safety requirement |
| Thermal profile | Centre, edge and process-stage temperatures | Validated product window |
| Product result | Dryness, cure and defect tests | Agreed quality method |
| Interlocks | Recorded challenge tests | Functional specification |
Empty-run temperatures do not represent absorption, evaporation or line loading. Run the intended substrate and coating at normal and boundary speeds. Check centre, edges, leading and trailing regions and downstream cooling.
Save zone settings, speed, airflow, sensor configuration and acceptance results. Photograph clean reflectors and record initial electrical readings for future comparison. Review YFR systems and controls and dryer modules.
No. Start under controlled conditions and increase only within equipment and product limits.
No. Use production material because absorption, evaporation and cooling alter the profile.
The defined interlock should reduce or remove heat before stationary product is damaged.
Engineering, production, quality and safety responsibilities should be assigned before acceptance.
Send YFR the dryer layout and acceptance criteria for a commissioning review.
