All data is for wet coil.
Example:
Reheat coil loss can be determined from the above table. Coil velocity (FPM) = Airflow (CFM) / Face Area (sq. ft.)
1. HKV120 has a face area of 11 sq. ft. (see physical data table).
2. At 4,200 cfm, coil velocity (FPM) = 4,200 / 11 = 380 FPM
3. From above table, ESP is .22.
4. HKV120 (without ClimaDry
®
) A Drive at .5 ESP, 2.5 turns = 4200 CFM
HKV120 (with ClimaDry
®
) A Drive at .72 ESP, 2.5 turns = 3900 CFM
If drop in CFM is not acceptable, adjust turns to 1.5 for 4200 CFM.
Note - Sometimes drive package must be changed.
