Pre-treated water enters via an inlet solenoid and is then
pumped through the purification pack, an ultrafilter and
temperature and water quality sensors before being
dispensed or re-circulated through a non-return valve back to
the pump inlet.
Ionic and organic impurities are removed by the purification
pack; the ultrafilter removes pyrogens, bacteria and other
microbial impurities as well as particles. Product water
resistivity and temperature are measured before dispense and
will indicate when the purification pack needs to be replaced.
The water within the unit is re-circulated through the
purification technologies to maintain purity. To reduce heat
build up the recirculation is at reduced flow rate and is set to
be intermittent (5 minutes every hour).
An optional POU filter is available if required to protect the
outlet from bacterial contamination.
