6. For minimum design airflow, see performance table for each unit.
7. To calculate the temperature rise in Celsius at different airflow, use the following formula: Temperature rise (C) across electric heater = (kW x 2985)/
(M3 / H).
8. To calculate the temperature rise in Fahrenheit at different airflow, use the following formula: Temperature rise (F) across electric heater = (kW x 3414)/
(1.08 / H).
