Notes:
1. Air temperature rise = (KW x 3413)/(scfm x 1.085).
2. All heaters on constant volume units provide 2 increments of capacity. All VAV units provide 1 step of heating capacity.
3. Air temperature rise in this table are based on heater operating at 240, 480 or 600 volts.

Note:
1. Second stage is total heating capacity. Second Stage/First Stage.
Notes:
1. KW ranges in this table are based on heater operating at 208, 240, 480, and 600 volts.
2. For other than rated voltage, KW =

x Rated KW.
Rated Voltage
3. Electric heaters up to 54 KW are single element heaters, those above 54 KW are dual element heaters.
