Model 7800 Series -Deionizer Control Systems

• Custom programmable for automatic precision and simplicity.
• Delivers duplex DI water more economically than any other deionizer.
• The most advanced DI control package available.
• No other DI controls offer so much performance at such a low price.

The digital-type meter displays both water quality and regeneration time remaining . . . a unique combination that simplifies system process planning. A third tank polisher can be accommodated under the single control to pick up sodium or silica leakage, allowing you to easily attain higher purity water at less expense. A single set of printed circuit boards control both simultaneous and sequential regeneration. You simply select the desired regeneration mode with DIP switches. All programming features are easily accessible on the front panel, so there`s no need to enter the control box and disrupt operations. Indicator lights show at a glance which phase of the regeneration cycle the system is in. Direct eduction of chemicals through the multiport valves eliminates additional chemical draw valves. Automatic prerinse prior to regeneration prevents false regeneration and preserves chemicals. Monitored final rinse rids the system of residual chemicals before the deionizer returns to service. Convenient test ports allow sampling of decationized and final DI water for quick, easy checks of system performance. Modular construction reduces downtime and simplifies troubleshooting and service. Rugged NEMA 12 electrical enclosures, standard on all controls, meet or exceed NEMA showering arc (ICS 2-230), surge withstand (IEEE 587) and electrostatic discharge (MIL-STD-88380). Automatic shutoff during power failure prevents resins from being exhausted past their quality endpoint. NOVRAM backup saves all data during a power failure, then returns the display to the last data point when power is restored. No batteries are required. A low level sensor can be easily wired into the control to warn of low chemical volumes. Provisions for a remote control panel and auxiliary "START REGENERATION" source allow regeneration to be initiated and controlled from a location remote from the actual installation site. Level controlled shutoff to a product storage tank can be utilized with the addition of a simple float switch in the storage tank.

Relays and fuses on the power printed circuit board provide for the operation of recirculation and supply pumps.
