(a) For minimum design airflow, see performance table for each unit.
(b) 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).
(c) 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).
