MODULE WATER FLOW DATA
FIGURE 3-4
1) In a primary-secondary pumping installation temperature rise thru the module has
no relation to system ∆T. In a parallel pumping installation temperature rise thru
the module equals the temperature drop of the system.
2) In a primary-secondary pumping installation pressure drop thru the module does
not add to system circulator head. In a parallel pumping installation pressure drop
thru the module does add to system circulator head load.
3) 40°F Temperature rise thru module recommended for Primary-Secondary pumping.
