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.
