The energy (kW) requirement is calculated from the following formula:
KW = |
SCFM x (Texit – Tinlet) |
|
2500 |
SCFM = Air flow in Standard* Cubic Feet per Minute Tinlet = Inlet Air Temperature (°F) (typically 70°F) Texit = Desired Exit Air Temperature (°F) |
|
Example: Heating 10 SCFM from ambient temperature (70°F) to 800°F:
KW = |
10 SCFM x (800°F – 70°F) |
= 2.9 kW |
|
2500 |

Conversion Formulas: (Liters per Minute)/28.3 = Cubic Feet per Minute °C = 5/9 (°F – 32) °F = 9/5°C + 32 |
