Tank Precharge Settings for use with
PENTEK INTELLIDRIVE™ Variable
Frequency Drives
Set the pressure tank's pre-charge to 70 percent of the
system operating pressure. When using an external set
point as well as an internal set point, pre-charge the
tank to 70 percent of the lower set point of the two.
Some applications may require a different percentage
when figuring the set point. Refer to your PENTEK
INTELLIDRIVE™ operator's manual for additional
information.
