Air Heating Engineering Insights
Air heating requires careful management of Face Velocity. If the airflow is too low, the heating elements may overheat and burn out. If it is too high, you may not achieve the desired temperature rise.
| Application | Typical Temp Rise | Recommended Element |
|---|---|---|
| Comfort Heating | 20°C – 40°C | Finned Strip Heaters |
| Process Drying | 50°C – 150°C | Tubular Duct Heaters |
| Heat Treating | 200°C+ | Stainless/Incoloy Open Coil |
Pro Tip: Always ensure a safety interlock is installed between the fan and the heater to prevent the heater from energizing without airflow.
