Process Description

Classic DI
Pre-treated water enters via an inlet solenoid and is then
pumped through the purification pack 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. 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.
