The PEDI-250
Deionized Water System is an integrated
modular complete skid mounted portable system
designed to produce Type II grade deionized
water from any potable water source. The
system is designed to provide deionized water
conveniently and economically to various
applications in the graphics arts, laboratory,
commercial and light industrial applications.
SYSTEM
FUNCTION:
The
PEDI-250 Deionized Water System is a complete
deionized (DI) water system that incorporates
a carbon prefilter, two deionizer (DI) service
exchange type canisters (tanks) with an indicator
light monitor in between and a sediment post
filter. The cartridge type carbon filter first
removes heavy sediments and chlorine from the
feed water to the system . Water then flows through
two (2) Calco, Ltd. SF-50 deionization canisters
(DI tanks) in a series connection. The first
canister is the worker and the second one the
polisher. The polisher tank provides a continuous
back up contingency of the operation. Finally,
the deionized (DI) water flows through a 5-micron
final sediment filter, which protects from fine
sediments entering the intended use of the purified
water. Between the two DI canisters there is
a resistivity indicator light that monitors the
water quality out of the first DI tank and alerts
the user (audible & visual) when the first
tank is nearing exhaustion and requires replacement.
The final product water is stored in the 7-gal
storage tank for use by the processor.
