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 trouble-shooting and service.
Automatic shut-off during power failure prevents resins from being exhausted past their quality endpoint. No batteries are required. A low level sensor can be easily wired into the control to warn of low chemical volumes. Level controlled shut-off 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.
