Performance Data
Force-Flo cabinet heater performance data is grouped based on performance. Unit performance
is impacted by the unit model and the airflow inlet and outlet configuration. Tab l e 5 summarizes
the performance groups.

Steam Pressure (psig) 2 5 10 15
Saturated Temperature (°F) 219 227 239 250
Latent Heat (Btu/lb) 965 960 952 945
Note: Q/ITD = MBh / (saturated steam temp - entering air temp) When Δ T and gpm remain
constant. To determine heating capacities at a different saturated steam or entering air
temperature, compute the new ITD and multiply it by the new Q/ITD shown.
