PERFORMANCE DATA (cont)
HYDRONIC HEATING CAPACITIES
LEGEND
*Based on 5 psig steam, 60 F entering-air temperature. All steam coils
are non-freeze type.
†Based on 200 F entering water, 20 F water temperature drop, 60 F
entering-air temperature.
NOTES:
1. Maximum operating limits for heating coils: 20 psig at 260 F.
2. Leaving db = ent db (F) +
3. See Heating Correction Factors table.
HEATING CORRECTION FACTORS
NOTE: Multiply capacity given in the Hydronic Heating Capacities table by the correction factor for conditions at which unit is actually
operating. Correct leaving-air temperature using formula in Note 2 of Hydronic Heating Capacities table.
