* Foleo is featured with variable refill therefore the salt quantity required is calculated by the controller at each regeneration
start. This maximum amount correspond to cases where 100% of the capacity would have been exhausted or to what a
standard softener without variable refill would consume.
NOTE

This example is calculated for a salt dosage fop 80 g/L
grated the 30°F it may be required to increase the salt dosage to obtain a proper resin bed
regeneration. The same simulation with 120 g/L
saving of 35,5%, while the same simulation done at 160 g/L lead to an estimated salt saving
of 46%.
