(3)Flow of cooling water
●In distillation of boiler water ,cooling water flows and drains from the decompressor, cooling
water solenoid valve to condenser. When distilled water tank is full of water or taking ion-
exchanged water , distillation stops and water flow and drain stops automatically.
(4)Collection of distilled water
● For about 10mim. from the beginning of distillation of boiler water , distilled water condensed in
condenser is stored into distilled water tank through electrode for distilled water, after
initial water is drained by
solenoid valve (to drain the initial distilled water) opened. The unit judges
water full and stops distillation when the highest float switch inside the tank is activated.
Distilled water stored is taken out by pump(to take distilled water) through solenoid valve to
take distilled water, distilled water flow sensor (WG221S only)and distilled water outlet.
