ADOX™ InLine (ClO2) Generator | International Dioxcide

ADOX™ InLine Generator

The Next Generation In Chlorine Dioxide Production

International Dioxcide’s patent pending design integrates the highest levels of safety, functionality, and industrial robustness in a self-contained modular design that is easy to install and requires a small footprint.

The critical design principle in the ADOX™ InLine generator is the reaction and delivery of chlorine dioxide in a safe, reliable, and easy-to-operate manner. The ADOX™ InLine generator uses sodium hypochlorite (bleach) and hydrochloric acid to react with the precursor sodium chlorite to generate chlorine dioxide.

The ADOX™ InLine chlorine dioxide generator offers:

Robust industrial design — needs minimal maintenance
Precise dosage control — eliminates wasted chemical
Patent pending design includes numerous built-in safety features
Vacuum-based design, chemical feeds are never pumped
Multiple operator modes
Highly efficient reaction
Wide production range
NSF 61 certified

All ADOX™ generators are affordable, safe, and highly efficient systems that can typically be installed and operating in one to two days. A supply of potable quality water, precursor chemical feed lines, a chlorine dioxide application line, and a power feed are the only connections required for most ADOX™ InLine installations.

Generation Reaction Chemistry

The ADOX™ InLine is used in heavy industrial applications. The ADOX™ InLine generator uses sodium hypochlorite (bleach) and hydrochloric acid to react with the precursor sodium chlorite to generate chlorine dioxide as shown below.

2NaClO2 + NaOCl + 2HCl = 2ClO2 + 3NaCl + H2O

This reaction theoretically yields 100% conversion of sodium chlorite to chlorine dioxide and a generator efficiency of greater than 95% of the theoretical yield is achievable. Alternative reaction chemistry using different precursors are also available from International Dioxcide. Capacities can range from 30 pounds per day to 10,000 pounds per day. Alternative reaction chemistry using different precursors are also available from International Dioxcide.

Features and Benefits

The ADOX™ InLine design centers around a safe, reliable, and easy-to-operate chlorine dioxide generator platform. The ADOX™ InLine utilizes an eductor so that the precursor chemicals are drawn from their storage under vacuum and remain under vacuum until the safely diluted reaction is complete. The proper flow of the motive water through International Dioxcide’s eductor-based technology creates a vacuum, which ensures that chemicals are only drawn into the generator when motive water is flowing. This approach minimizes any chance for precursor leakage or unsafe chemical reactions.

The vacuum based ADOX™ InLine design eliminates the need for metering pumps with their inherent need for frequent maintenance, reliability problems, and concerns with high pressure leaks of hazardous chemicals. If the motive water supply water is lost, vacuum is no longer being created and chemicals will stop being pulled into the generator. The ADOX™ InLine chemical reaction takes place in the dilution water to ensure that the chemical concentrations are proportionally maintained at a safe level, whereas, this would not be the case with metering pumps.

Other important features include:

Highest efficiency — 95%+ efficient
Filters on all chemical feeds to ensure reliable feed
Check valves on all chemicals to avoid backflow
ClO₂ produced is immediately diluted
Clear schedule 80 piping at eductor area to monitor the chlorine dioxide generation
Multiple operational modes for greater operational flexibility
- Operator controlled — manual ClO₂ generation
- Flow compensating auto dosing
- Dynamic auto dosing based on feedback sensors
Water monitoring and remote WAN monitoring capable
No “pre-reaction” chamber to flush
No build-up of salt scaling in eductor
Eductor-based design for increased safety (elimination of all chemical pumps)
Increased chemical reaction safety due to 100% of the chemical reaction occurring in water
Wide production range capability (up to 10,000 ppd)
Small footprint ~ 57″ L x 31″ W x 43″ H
Engineered with highest safety standards

Electrical and Controls

The ADOX™ MG Inline utilizes a simple and easy-to-learn operational interaction between the user and the generator equipment making the task of operating the generator effortless. To ensure reliable operation International Dioxcide engineers selected generator components that have met International Dioxcide’s stringent standards for quality and reliability during the company’s 70+ years of operation. If service is needed the user-friendly design layout will make the repair easy for trained staff. All electrical systems are audited to UL 508A standards. Additional items include:
