1.
Unit resistance based on a wet evaporator coil, clean filters, and unit tested in horizontal configuration.
2.
Available static pressure in IWG to overcome the resistance of the duct system and any accessories added to the unit. Refer to the respective tables
for the resistance of these accessories and for additional motor and drive data.
3.
Motors can be selected to operate into their service factor because they are located in the moving airstream, upstream of any heating device.
4.
kW is based on 6% drive losses and a motor efficiency of 83.1%. Calculate kW by using the following formula:
kW = (746 X BHP X DRIVE
LOSSES) / (1000 X MOTOR EFFICIENCY)
