Performance based on 2# steam pressure (13.8 kpa) at heater with air entering @ 60°F (16°C). For Sound Ratings See Pages 28 and 29.

Use conversion table for all metric conversions.

* For the lower output, an optional Speed Controller must be ordered.

†Stated AMP is full load for the standard motors. AMP draw varies by motor manufacturer ± 0.2 AMPS. Please see your unit's motor data plate for exact (FLA) Full Load Amp rating.

B. For capacities calculated in I.B. (above)

 

Output from I.B./1.085 x CFM from Table 20 +

30,960/1.085 x 450 + 40 = 103.4°F.

 

 

 

 

 

 

E.A.T. = Final Air Temp

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

III. FINAL AIR VOLUME

 

 

 

460 + Final Air Temp from Table 20 / 530 x Nom.

460 + 109 / 530 x 450 = 483 CFM

A. For 2 lbs. steam, 60° entering air

 

 

CFM from Table 20 = Final Air Volume

 

 

 

 

 

 

 

 

 

 

B. For final air temperatures calculated in II.B.

460 + Final Air Temp from II.B. / 530 x Nom. CFM

460 + 103.4 / 530 x 450 = 478 CFM

(above)

 

 

 

 

 

from Table 20 = Final Air Volume

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

IV. CONDENSATE PER HOUR

 

 

Read lbs. per hour from Table 20, 24.5 LBS./HR.

 

 

 

 

A. For 2 lbs. steam, 60° entering air

 

 

(Ref., Std. 24).

 

 

 

 

 

 

 

 

 

 

 

 

 

B. For capacities calculated in I.B. (above)

 

Output from I.B. / Latent Heat From Table 23 =

30,960 / 953 = 32.5 LBS./HR.
