Chlorine Dioxide Generator CAPITAL CONTROLS МОДЕЛЬ G50

Order

The CAPITAL CONTROLS^® G50 chlorine dioxide generator is a two-chemical system, utilizing chlorine gas and 25 – 31 wt % sodium chlorite in the production of chlorine dioxide. A proven design, durable construction and the use of the best available corrosion-resistant materials assure efficient chlorine dioxide production, precise solution feeding, low maintenance and dependable operation for the life of the equipment.

KEY BENEFITS

All Vacuum System: The reagents are drawn into the generator by a vacuum, produced by an integral ejector. The chlorine dioxide gas produced by the generator is mixed with the ejector motive water and applied as a solution.
Capacities: standard chlorine dioxide generator units are available in a range of capacities from 5 kg/h to 50 kg/h of chlorine dioxide gas.

DESCRIPTION OF OPERATION

The chlorine gas and sodium chlorite reagents are drawn into the generator under a vacuum, produced by an integral ejector. Reagent ﬂow is controlled by Chloromatic™ valves, which are individually sized for each dosage capacity.
The chlorine dioxide gas is drawn out of the reaction chamber under a vacuum produced by the integral ejector where it is mixed with the ejector motive water and applied as a solution. The solution is passed through a sight glass for visual verification of product quality. The entire system is completely under vacuum from reagent draw into the generator to the ejector. If a low vacuum condition exists, valves will shut-off reagent ﬂows to the generator. A low vacuum alarm contact is included. An automatically controlled system utilizes input signals for ﬂow or residual.
