Table 14 — Fan Performance Data (English) — 50TJ028* (25 Tons)
LEGEND
*Standard drive range for Low-Medium static drive on 50TJ028 is 888 to
1069 rpm. Standard drive range for High static drive on 50TJ028 is 1114 to
1341 rpm. Other rpms require a field-supplied drive.
NOTES:
1. Maximum continuous bhp is 13.3 (400 v) or 11.5 (220 v). The maximum
continuous watts is 11,000 (400 v) or 9600 (220 v). Do not adjust motor
rpm such that motor maximum bhp and/or watts is exceeded at the maxi-
mum operating cfm.
2. Static pressure losses (i.e., EconoMi$er) must be added to external static
pressure before entering fan performance table.
3. Interpolation is permissible. Do not extrapolate.
4. Fan performance is based on wet coils, clean filters, and casing loses. See
Table 16B for accessory/FIOP static pressure information.
5. Extensive motor and drive testing on these units ensures that the full brake
horsepower and watts range of the motor can be utilized with confidence.
Using your fan motors up to the watts or bhp rating shown will not result in
nuisance tripping or premature motor failure. Unit warranty will not be
affected.
6. Use of a field-supplied motor may affect wiring size. Contact your Carrier
representative for details. For additional information on motor performance,
refer to Evaporator-Fan Motor Performance Table 19.

NOTES:
1. The static pressure must be added to external static pressure.
The sum and the evaporator entering-air cfm should then be
used in conjunction with the Fan Performance tables to deter-
mine blower R/s and watts.
2. Heaters are rated at 400 v.
