(a) Minimum allowable airflow with a 54 kW heater is
3400 CFM

27.0 2 21.3
36.0 2 28.5
54.0 2 42.7
Notes:
1. For minimum design airflow, see airflow
performance table for each unit.
2. To calculate temp rise at different airflow, use the
following formula:
Temp. rise across Electric Heater = kWx3414/
1.08xCFM.
