High Efficiency
Factory supplied motors, in commercial equipment, are
definite purpose motors, specifically designed and tested to
operate reliably and continuously at all cataloged conditions.
Using the full horsepower range of our fan motors as shown
in our tabular data will not result in nuisance tripping or
premature motor failure. Our product’s warranty will not be
affected.
For Standard Evaporator Fan Speed (RPM), reference Table PD-31.
For Standard Motor & High Static Drive Accessory Fan Speed (RPM), reference Table PD-32.
For Oversized Evaporator Fan Speed (RPM), reference Table PD-33.
Table includes Dehumidification (Hot Gas Reheat Option).
*Unit applications below 4800 CFM
• Electric heaters restricted on applications below 4800 CFM.
• Dehumidification (Hot Gas Reheat) or TXV with Frostat and Crankcase Heaters
are required on applications below 4800 CFM.
Fan motor heat (MBH) = 3.15 x Fan BHP
Data includes pressure drop due to wet coils and filters.
No accessories or options are included in pressure drop data.
Refer to Table PD-35 to determine add’l static pressure drop due to other options accessories.
Note:
1. Field Supplied Fan Sheave BK120 Required. Field Supplied Belt may be necessary. Field
Supplied Belt may be necessary.
2. Field Supplied Fan Sheave BK160 Required. Field Supplied Belt may be necessary. Field
Supplied Belt may be necessary.
