1.
Select the model, which has a flow rate that is greater
than the maximum filling rate or discharge rate of the pump,
which empties the tank.
2.
Decide upon the period of time (usually months) you require
between changes of desiccant in the Storage Tank Vent Dryer.
Calculate the volume of liquid, which will be drawn from
the tank during that period. Select a model, which will
give you a capacity greater than the calculated volume.
3.
The unit that should be used will be the larger of the models
from the results of 1 & 2 above.
4.
Atmospheric pressure and temperature changes will affect
desiccant life. A temperature change of 35° F per day
will cause the Storage Tank to breather 7.5% of the free
air space volume.
