To size a ThermaPhase unit, you must know the
volume of air being compressed, the relative humidity of the air
and the inlet temperature. Table 1 is a chart showing the
SCF/M of compressed air required to produce one gallon per hour of
condensate at various inlet temperatures and relative humidities.
|
Step 1
|
Locate on Table
1 the SCF/M of air factor using the inlet temperature
and relative humidity of the application. |
|
Step 2
|
Divide the SCF/M of air
required by the application of the SCF/M of air factor
obtained from Table 1. This
number is the gallons of condensate per hour required to be
processed by the ThermaPhase. |
|
Step 3
|
Pick a ThermaPhase unit
with capacity to handle the condensate from Table
2. |
500 SCF/M • Air Temp - 70ºF
• Relative Humidity -70%
|
Step 1
|
Refering to Table 1 for
an air temperature of 70ºF and a relative humidity of 70%,
we find an air factor of 174.3 |
|
Step 2
|
Dividing our compressor
capacity of 500 SCF/M by the air factor:
500SCF/M / 174.3 SCF/M/Gal/Hr
= 2.87 Gal/Hr.
|
| Step 3 |
Refering to Table 2, we
find it takes a ThemaPhase TP-12 to handle this application. |
