For minimum design airflow, see airflow performance table for each unit.
To calculate temp rise at different air flow, use following formula:
Temp. Rise across Elect. Htr =
KW x 3413
1.08 x CFM
Notes:
1. Not available on TC*210 model.
2. 27KW heater can be used with TCD181C4, TCD211C4, TCD241C4 andTCD301C4 only. Cannot be used with oversized motor.
